Polypropylene (PP filament)
PP is a thermoplastic resin prepared by polymerization of propylene.
The price of PP brush filament is relatively cheap compared with other synthetic fibers filament, and the cost is high.
The biggest feature of PP brush filament is that the density is less than 1, which can be placed in the water when testing the wool material, and if it floats on the surface of the water, it can be preliminatively determined as PP material.
The cross section of PP brush filament is elliptical;
In addition, the elasticity of PP brush filament is poor, and it is difficult to restore the original shape after multiple bending;
PP brush filament can be heat resistant to 120 degrees Celsius, suitable for industrial dust removal and cleaning for more rugged parts, such as mine and dock dust removal, sanitation truck sweeping brush and so on.
