While the bristles used can be a wide variety of materials, most often nylon is used. The reason for this is nylon is flexible, and can be easily be bent but will also easily come back to its regular form, and stay strong and wear little due to the bending. It also offers high abrasive resistance and can even be impregnated with metal to increase its abrasiveness.

Strip brushes are long and thin. The bristles are arranged neatly and clamped between aluminum or steel channels. The bristles can be made from metal, polymer or natural substances. They can range from a few inches to a few feet in length depending on what the need is. An added bonus to these brushes is they don’t have to be straight. While this is definitely the most common form of strip brushes, they can also be curved or even round like thin wheel brushes. Many companies can even custom make brushes to make sure every client has the best possible brush.

Closing doors doesn’t always completely block out sound or completely seal off the room. Sound or small items are often able to slide underneath the doors in the small gap between door and floor. In these situations, strip brushes can be applied to completely seal off the room from the outside world. This could be applied to such places as the
restaurant industry, where it is nice to block as much of the kitchen sound as possible from reaching the customers. Or if a plate crashes in the back, it is able to ensure no tiny glass pieces are able to slide out into the main part of the restaurant. Strip brushes can be used to seal off doors, windows, conveyor edges, cracks and any other item that might need a flexible seal.

The polymer properties give nylon(PA) brushes superior abrasion resistance, high heat tolerance, great chemical resistance and bend recovery. Nylon(PA) is one of the most commonly used polymers in brushes. The stiffness of a nylon(PA) brush is directly related to bristle diameter, length and grade. Nylon(PA), depending on the grade, is more costly than lower grade polymers; however, the advantages justify the higher price. Some of the many advantages of nylon(PA) include low to moderate water absorption, an excellent fatigue life and the ability to work in both dry and wet environments. For industries such as semiconductor, aerospace, medical, food processing, automotive, commercial, industrial, textiles and electronics, nylon(PA) brushes are vital components in many processes due to extensive application-specific configurations. There are also a variety of colors of nylon(PA) filament, which is available in its natural milky clear color, or in dyed colors such as black or yellow.
