What are the characteristics of nylon PA bristles?

October 28, 2022
Among the bristle materials used for brush making, Nylon Brush Filament is a relatively common type of material, which is used in beauty salons, oral cleaning, textile processing, glass cleaning, and construction industries. What are the characteristics of nylon PA bristles?

The characteristics of Polyamide Filament Nylon Bristle mainly include several aspects: hardness, bending recovery force, chemical resistance, abrasion resistance, water absorption, temperature resistance, etc.

Soft hardness: Under the same diameter, Heat Resistance Nylon Filament has the lowest hardness among all kinds of plastic bristles, and the PA material has a high water absorption rate, which is easy to absorb moisture in the air and become soft.


What are the characteristics of nylon PA bristles?


Bending recovery: High Temperature Resistant Nylon Filament has excellent bending recovery, can recover quickly after bending, has good bending fatigue resistance, and is not easy to deform after long-term use.

Chemical resistance: Nylon Brush Filament has good alkali resistance, oil resistance, weak acid resistance, but not strong acid resistance, and is easily soluble in phenol, formic acid, etc.

Temperature resistance: The melting point of nylon PA bristles is in the range of 200-295 degrees Celsius, and the heat distortion temperature is 100-150 degrees Celsius. The temperature resistance is the best among ordinary plastic bristles. The suitable maximum working environment temperature range is about -30 -150℃.

Wear resistance: Nylon PA bristles have excellent wear resistance, self-lubrication, and low friction coefficient, which can prolong the service life of toothbrushes and industrial brushes.

To sum up, the main characteristics of nylon PA bristles are: softness, wear resistance, alkali resistance, weak acid resistance, oil resistance, good bending recovery, high and low temperature resistance, water absorption, etc. We specialize in customizing different diameters and colors for customers!
