Nylon, Plastic and Synthetic Filament Brushes | The Complete Guide

Introduction: why does choosing the right brush material matter so much?

Have you ever bought the wrong brush and had it worn out and scrapped in less than a month? Or found that it did not clean as well as expected and scratched the surface of expensive equipment instead?

In the industrial brush market, nylon brushes, plastic brushes and synthetic filaments are the three mainstream materials. Many buyers and plant managers do not know which one to choose, and end up paying for the wrong brush, getting poor results and even hurting production efficiency.

This article is written by the manufacturing team at YC Brushes, which has over 40 years of professional experience. It gives a complete account of how the three materials differ in their properties, where they are used, what they cost and how to buy them. After reading it you will know clearly: when should you choose a nylon brush? Which applications suit a plastic brush? What are the advantages of synthetic filaments? How do you avoid the pitfalls?

Whether you are a factory buyer, an equipment maintenance technician, or a reader who simply wants to learn about brushes, this article will help you reach the right decision quickly.

What are nylon brushes, plastic brushes and synthetic filaments? Definitions and basics

Before comparing them in depth, let us be clear about what these three materials actually are.

Definition and properties of nylon brushes

A nylon brush is a brush made with polyamide (PA).

There are two main grades:

• Nylon 6 (PA6): lower cost, higher moisture absorption, suitable for temperatures up to 80°C
• Nylon 66 (PA66): higher strength, heat resistance up to 120°C, better chemical resistance

Physical properties:

• Extremely wear resistant, with a service life of 2-3 years
• Good elasticity, does not deform easily, recovers quickly
• A wide temperature range: -40°C to 120°C
• Higher moisture absorption (about 3-5%), softening slightly in humid environments

Common applications:

• Industrial cleaning brushes (nylon wheel brushes, nylon tube brushes)
• Polishing and abrasive brushes
• Brushes for food processing equipment (must comply with FDA food-contact regulations)
• Deburring brushes

The biggest advantage of a nylon brush is durability. If your application involves frequent use and high-intensity work, a nylon brush is the first choice.

It has drawbacks too: it costs more than an ordinary plastic brush, and it degrades in strong acid and alkali environments.

Definition and properties of plastic brushes

"Plastic brush" is a broad term. It usually refers to brushes made with materials such as PP (polypropylene), PET (polyester) and PE (polyethylene).

Physical properties:

• Resistant to chemicals, withstands strong acids and alkalis
• Economical, with good cost control
• Moderate hardness, suited to general cleaning
• Does not absorb water, dries quickly and does not go moldy easily

The common materials in detail:

• PP brush: resistant to acids and alkalis, does not absorb water, inexpensive; the most common
• PET brush: hardness between nylon and PP, good recovery, suited to road sweeping brushes
• PE brush: the softest, does not damage surfaces, suited to cleaning precision parts

Common applications:

• Household cleaning brushes (bathroom brushes, floor brushes)
• Industrial sweeping brushes, disc brushes for floor sweepers
• Anti-static brushes
• Food-grade brushes (must comply with food safety certification)

The advantages of plastic brushes are economy and good chemical resistance.

The drawback is poorer wear resistance: the service life is usually only 1-2 years, and for heavy-duty industrial cleaning they are no match for nylon brushes.

Definition and scope of synthetic filaments

Synthetic filament is the general term for all man-made fiber brush filaments, including nylon, PP, PBT, PET and other materials.

In other words, nylon brushes and plastic brushes are both kinds of synthetic filament brush.

Advantages over natural bristle (hog bristle, horsehair):

• Contains no animal ingredients, in line with animal-friendly values
• Stable quality, does not shed easily, little variation between batches
• Hardness, diameter and length can be customized
• Good chemical resistance, suited to industrial environments
• Some materials are recyclable (such as PET and PP), which is environmentally sustainable

Market trend:

In recent years synthetic filaments have gradually replaced natural bristle and become the mainstream in industrial brushes.

The reason is simple: the quality of natural bristle is affected by the season and the place of origin, so it is unstable; with synthetic filaments the specification can be controlled precisely and the quality is consistent.

If you need to purchase in volume, or have requirements for quality stability, synthetic filament is definitely the better choice.

Nylon brushes vs plastic brushes vs synthetic filaments: a full comparison of the three materials

After all these definitions, you may still be unclear about which one to choose.

Let me help you grasp the key points quickly with one complete comparison table.

Material performance comparison table

The table shows that:

• Wear resistance: nylon brushes win outright, plastic brushes are average
• Chemical resistance: plastic brushes (PP) are stronger, nylon brushes come second
• Price: plastic brushes are the cheapest, nylon brushes cost more
• Service life: nylon brushes last longest, plastic brushes are shorter-lived

How to choose according to the application

Having read the comparison table, you may still not know which one to choose.

Let me tell you directly how to choose according to your application.

1. Heavy-duty industrial cleaning → choose a nylon brush

Reason: wear resistant, high strength, long service life

Examples: deburring metal surfaces, polishing and abrasive finishing, cleaning machinery

2. Food / pharmaceutical industry → choose a nylon or PP brush that complies with FDA food-contact regulations

Types and applications of nylon brushes in detail

Now that the basic differences are clear, let us look more closely at the types of nylon brush.

Common product types of nylon brush

There is more than one kind of nylon brush. Depending on the purpose, the common types are as follows:

1. Nylon wheel brush (Nylon Brush Wheel)

This is the most common nylon brush for industrial use.

Purpose: abrasive finishing, deburring, polishing

Specifications:

• Diameter: 50mm-300mm
• Bore: 22.2mm or 25.4mm (to fit bench grinders)
• Filament diameter: 0.3mm-1.0mm

Suitable equipment: bench grinders, power tools, automated production lines

Want more detail? See our complete buying guide to nylon wheel brushes, which has detailed advice on choosing specifications.

2. Nylon tube brush (Nylon Tube Brush)

A brush made specifically for cleaning the inner wall of pipes and tubes.

Purpose: pipe cleaning, removing deposits, maintaining food equipment

Specifications:

• Diameter: 5mm-100mm
• Length: made to order (usually 30cm-200cm)
• Handle: twisted-wire handle, plastic handle, flexible handle

Industries: food processing, medical equipment, machinery maintenance, air-conditioning lines

The key with a nylon tube brush is choosing the right size. The brush head diameter should be 1.2-1.5 times the inner diameter of the tube for effective cleaning.

3. Strip brush (Strip Brush)

A strip-shaped brush in which nylon filament is fixed in a metal or plastic strip.

Purpose:

• Sealing doors and windows, dust strips
• Conveyor belt cleaning
• Protecting industrial equipment

Specifications:

• Base width: 5mm-50mm
• Trim length: 10mm-100mm
• Length: orders usually start at 1 meter

If you need to install strip brushes, we suggest reading the strip brush hardware installation guide, which covers the full measuring and installation steps.

4. Hard nylon brush (Hard Nylon Brush)

A nylon brush with thicker filament (0.5mm-1.0mm) and high stiffness.

Purpose: cleaning heavy soiling, surface treatment, removing stubborn deposits

Suited to: industrial floor cleaning, equipment maintenance, building cleaning

Hard nylon brushes clean powerfully but also scratch surfaces easily. Always confirm material compatibility before use.

Nylon brush material grades: nylon 6 vs nylon 66

As mentioned above, nylon brushes come in two grades, PA6 and PA66.

What exactly is the difference, and which one should you choose?

Nylon 6 (PA6):

• Lower cost
• Higher moisture absorption (takes up moisture and softens easily)
• Suitable temperature: up to 80°C
• Suited to general industrial use

Nylon 66 (PA66):

• Higher strength
• Heat resistance up to 120°C
• Better chemical resistance
• Lower moisture absorption
• Higher price

Recommendation:

• Limited budget, general cleaning → PA6 is enough
• High-temperature environment (80-120°C) → PA66 is required
• Heavy industry, high-intensity work → PA66 is recommended
• Humid environment → PA66 is better (low moisture absorption)

An example:

If you run a food plant and need to clean high-temperature steam pipes (100°C), you must choose PA66.

If it is just ordinary factory floor cleaning, PA6 is enough and saves cost as well.

Types and applications of plastic brushes in detail

With nylon brushes covered, let us look at plastic brushes.

Common material types of plastic brush

Plastic brushes are not a single material. There are three common ones:

1. PP brush (polypropylene brush)

The most common plastic brush, with the highest market share.

Properties:

• Resistant to acids and alkalis, withstands chemical corrosion
• Does not absorb water and dries quickly
• Inexpensive and economical
• Moderate hardness

Uses:

• Cleaning brushes, brooms
• Car wash brushes
• Floor brushes
• Industrial sweeping brushes

The biggest advantages of a PP brush are that it is cheap, durable and unaffected by chemicals.

If your budget is limited, a PP brush is definitely the first choice.

2. PET brush (polyester brush)

Hardness between nylon and PP, with good recovery.

Properties:

• Does not absorb water, does not deform easily in outdoor use
• Good weather resistance, UV resistant
• Good elasticity and recovery

Uses:

• Road sweeping brushes
• Industrial sweeping
• Outdoor brushes

PET brushes suit outdoor environments, for example the main brush of a floor sweeper or the disc brushes of a road sweeping truck.

3. PE brush (polyethylene brush)

The softest plastic brush.

Properties:

• Very soft, does not damage surfaces
• Suited to precision cleaning
• Low price

Uses:

• Cleaning precision parts
• Scrubbing soft surfaces
• Car detailing

PE brushes are very soft and suit situations that need gentle cleaning.

If you need to clean painted surfaces, glass or precision parts, a PE brush or a soft brush is a good choice.

Applications of plastic brushes

Plastic brushes are used very widely. The common scenarios are:

Household cleaning:

• Bathroom brushes, toilet brushes
• Floor brushes, window brushes
• Shoe brushes, clothes brushes

Industrial sweeping:

• Disc brushes for floor sweepers

Advantages of synthetic filaments and market trends

Having covered nylon brushes and plastic brushes, let us turn to the overall advantages of synthetic filaments.

Why choose synthetic filaments?

Compared with natural bristle (hog bristle, horsehair), synthetic filaments have the following advantages:

1. Quality stability

The quality of natural bristle is affected by the season, the place of origin and the health of the animal, so it varies a lot between batches.

Synthetic filaments are produced industrially, so every batch is consistent in quality and precise in specification.

If you need to purchase in volume, synthetic filaments are definitely more stable.

2. Customizable function

With synthetic filaments the following can be adjusted:

• Hardness (Shore A 50-90)
• Filament diameter (0.1mm-2.0mm)
• Filament length
• Added functions (anti-static, antibacterial, high-temperature resistant)

Natural bristle cannot do this.

For example, the electronics industry needs anti-static brushes, and only synthetic filaments can be used for them.

3. Environmentally sustainable

Synthetic filaments do not involve killing animals, in line with animal-friendly values.

Some materials (such as PET and PP) are recyclable, which is environmentally sustainable.

By comparison, the way natural bristle is obtained is more controversial.

4. Economic benefit

The service life of synthetic filaments is usually longer than that of natural bristle.

Calculated as total cost (unit price × service life), synthetic filaments are often better value.

Synthetic filaments also do not shed easily, which reduces the contamination risk. This is especially important in the food and medical industries.

Applications of synthetic filaments by industry

Synthetic filaments are already widely used across the major industries:

Food industry:

• Nylon brushes and PP brushes that comply with FDA food-contact regulations
• Cleaning food processing equipment
• Conveyor belt brushes
• Fruit and vegetable washing brushes

Electronics industry:

• Anti-static brushes
• Dedicated cleanroom brushes
• PCB cleaning brushes
• Dust-removal brushes for precision parts

Automotive industry:

• Car wash brushes
• Polishing brushes
• Wheel rim cleaning brushes
• Interior cleaning brushes

Construction industry:

• Paint brushes
• Waterproofing brushes
• Cleaning brushes
• Site sweeping brushes

It is fair to say that almost every industry uses synthetic filaments.

The trend for the future is that synthetic filaments will continue to replace natural bristle and become the mainstream.

Strip brushes: specifications and buying guide

The strip brush is a special form of brush with a very wide range of applications.

What is a strip brush?

A strip brush is a strip-shaped brush in which the filament is fixed in a metal or plastic strip.

Soft brushes vs hard brushes: a guide to choosing stiffness

Besides the material, the stiffness of the filament is also an important consideration when buying.

What determines filament stiffness

Filament stiffness is not fixed. It is determined by the following factors:

1. Filament diameter

The thicker, the stiffer; the finer, the softer.

• 0.1-0.3mm: soft brush
• 0.4-0.6mm: medium stiffness
• 0.7-1.0mm: hard brush
• 1.0mm and above: extra-hard brush

2. The material itself

Different materials differ in their inherent hardness.

Hardness ranking: nylon > PBT > PP > PE

3. Filament length

For filament of the same diameter, the shorter it is the stiffer, and the longer it is the softer.

4. Tufting density

With the same material and diameter, the denser the tufting the stiffer the brush, and the sparser the softer.

Applications of soft brushes

The characteristic of a soft brush is that it is gentle and does not damage surfaces.

Suitable scenarios:

• Cleaning precision parts (electronics, optics)
• Painted car surfaces
• Furniture polishing
• Food processing equipment (washing fruit and vegetables)
• Jewelry cleaning
• Musical instrument care

If your application needs gentle cleaning without scratching, a soft brush is the first choice.

Want to know more about choosing soft brushes? See Soft brush recommendations: where to buy? | Recommended professional manufacturers.

Applications of hard brushes

The characteristics of a hard brush are strong cleaning power and wear resistance.

Suitable scenarios:

• Heavy industrial cleaning
• Floor sweeping (factories, warehouses)
• Deburring and polishing
• Removing stubborn dirt
• Outdoor cleaning (stone, concrete)

If your application needs powerful dirt removal, a hard brush is the first choice.

But take care: hard brushes scratch surfaces easily. Always confirm material compatibility before use.

Recommendation:

• Not sure whether to choose soft or hard → start with medium stiffness
• Worried about scratching → choose a soft brush
• Not enough cleaning power → switch to a hard brush
• Cannot judge → ask for samples and test them

Price analysis and purchasing advice for nylon and plastic brushes

After all these technical details, what you probably care about most is: how much will it actually cost?

The key factors that affect price

Brush prices are not fixed. They are mainly affected by the following factors:

1. Material grade

Price ranking: nylon 66 > nylon 6 > PBT > PET > PP > PE

For example:

• A nylon 66 brush usually costs a good deal more than a PP brush
• But its service life is also 2-3 times longer

So do not look only at the unit price; look at the total cost (unit price × number of uses).

2. Manufacturing process

• Hand tufting vs machine tufting (hand tufting costs more)
• Base material (plastic < aluminum alloy < stainless steel)
• Tufting density (the denser, the more expensive)

3. Custom requirements

• Standard products are cheaper
• Custom work requires tooling, so the cost is higher
• Quantity affects the unit price (MOQ, the minimum order quantity)

4. Brand and origin

• Imported brands cost more
• Made in Taiwan means good quality at a reasonable price
• Made in China is the cheapest, but quality is uneven

Market price reference

The following are market reference prices. Please ask the manufacturer for an actual quote.

Disclaimer: prices are for reference only and vary with specification and quantity

Price observations:

• PP brushes are the cheapest and suit limited budgets
• Nylon brushes are in the upper mid-range, but they last long, so the total cost is good value
• For custom brushes the quantity needs to be assessed; the larger the quantity, the lower the unit price

Purchasing advice and things to watch

Buying brushes is not only about price. Here is our professional advice.

• Resistance to chemicals and strong acids and alkalis
• General cleaning, household or light industrial use
• No water absorption, outdoor use

Choose synthetic filament if you need:

• Stable quality, consistent from batch to batch
• Customized functions (anti-static, antibacterial)
• Environmental sustainability and animal-friendly materials
• Volume purchasing with precise specifications

Final reminders before purchasing

1. Look at the total cost, not only the price

   • A cheap brush may need replacing often and end up costing more
   • Total cost = unit price × number of replacements

2. Always ask for samples to test

   • What works on paper may not match reality
   • Confirm the results with an on-site test

3. Choose an experienced manufacturer

   • YC Brushes, with over 40 years of experience
   • Factory-direct, with transparent pricing
   • Custom service, with order quantities quoted per specification

4. Confirm the material certification

   • Food grade must comply with the Sanitation Standard for Food Utensils, Containers and Packages (and with FDA 21 CFR 177 for export to the US)
   • Environmental compliance needs to meet the EU REACH regulation
   • Quality needs ISO certification
