Product Overview
The Polypropylene Strip Brush, also commonly known as a PP strip brush or poly strip brush, is manufactured with polypropylene bristles securely fixed in a metal channel backing. It is a cost-effective strip brush for sealing, cleaning, wiping and dust control in a wide range of industrial applications.
Polypropylene bristles have low moisture absorption and good resistance to many chemicals, making this brush particularly suitable for humid environments and applications where occasional contact with water or chemicals may occur. The metal backing is available in galvanized steel or stainless steel to suit different working conditions.
As a polypropylene seal brush, it can be installed on machinery, conveyor systems, doors, cabinets and equipment openings to help reduce the passage of dust, debris, air and light. Brush length, bristle height, bristle color and metal backing size can be customized according to the installation and application requirements.

Materials
Polypropylene (PP) Bristles: Polypropylene is a cost-effective synthetic filament with low moisture absorption and good resistance to many chemicals. PP bristles are available in different diameters, colors and densities to meet different sealing and cleaning requirements.
Metal Channel Backing: The polypropylene bristles are securely fixed into a U-shaped metal channel with a retaining rod. Galvanized steel is commonly used for general industrial applications, while stainless steel is available for applications requiring better corrosion resistance.
Applications
Polypropylene strip brushes are widely used for sealing, cleaning and dust control in industrial equipment and general commercial applications. Their low moisture absorption and cost-effective PP bristles make them particularly suitable for applications where economical and reliable brush performance is required.
- Industrial Machinery – Used around machine openings, moving parts and equipment gaps to help control dust, debris and light.
- Conveyor Systems – Installed along conveyor edges, transfer points and openings for cleaning, guiding and containing loose debris.
- Doors and Gates – Used as a straight strip brush for sealing gaps along door bottoms, sides and industrial entrances.
- Cabinets and Enclosures – Helps reduce the entry of dust and debris through gaps, openings and access points.
- Cleaning and Wiping Equipment – PP bristles can be used for general surface cleaning, wiping and light sweeping applications.

Frequently Asked Questions
What is a polypropylene strip brush used for?
A polypropylene strip brush is commonly used for sealing, dust control, cleaning, wiping and guiding. It can be installed on industrial machinery, conveyor systems, doors, cabinets and equipment openings.
What is the difference between PP and nylon strip brushes?
PP bristles have lower moisture absorption and are generally more economical than nylon bristles. They also offer good resistance to many chemicals. Nylon typically provides better abrasion resistance and resilience, so the best material depends on the working environment and application.
Can polypropylene strip brushes be used in wet environments?
Yes. Polypropylene absorbs very little water and is suitable for many humid or wet environments. However, the metal channel material should also be selected according to the environment. Stainless steel backing is recommended where better corrosion resistance is required.
Can the size and bristle density be customized?
Yes. Brush length, bristle height, bristle thickness, bristle density, metal channel size and other specifications can be customized. Different bristle densities can be selected depending on whether the brush is used primarily for sealing or cleaning.
Can you manufacture PP strip brushes according to a drawing or sample?
Yes. We can manufacture custom PP strip brushes according to your technical drawing, dimensions, sample or application requirements. Please provide the required brush length, bristle height, filament diameter, metal channel size and quantity when requesting a quotation.
