The major material of brush filaments are polyester, polypropylene and nylon. Polyester is PET, PBT, polypropylene is PP filament, Nylon filament is divided into pa6, pa66, pa610, pa612, what are the characteristics of brush fiber of these materials?
1, PET, PBT filament chemical name Polybutylene terephthalate, excellent elasticity, good wear resistance, good recovery, low water absorption, high cost performance, excellent solvent resistance, excellent oxidation resistance, no water absorption , good abrasion resistance, excellent bending recovery, excellent heat resistance, but susceptible to halogenated hydrocarbons.
2, The chemical name of PP brush filament is polypropylene, which is one of the lightest varieties of all plastic brush wires at present. It has excellent hardness properties (good hardness), but the elasticity, temperature resistance, wear resistance and recovery force are the worst.
3, The chemical name of PA6 brush filament is polyamide, which is resistant to alkali, soluble in phenol, formic acid, etc.; softer than PA66, good fluidity, stable size, better performance than PA66, high water absorption, low resilience, temperature resistance and recovery force ratio PA66 is poor, and its elasticity (hardness) is worse than that of PP and PBT; chemical name of PA66 brush wire is polyhexamethylene adipamide, alkali-resistant, but easily soluble in phenol, formic acid, etc.; hardness, melting point, recovery force, and the most temperature-resistant, It is the best in nylon; the chemical name of PA610 brush filament is polyhexamethylene sebacate, which has excellent mechanical properties, strong wear resistance, good impact resistance and low temperature performance, and good chemical stability. Low water absorption, (good corrosion resistance) strong alkali resistance, weak acid resistance is better than PA6 brush wire and PA66 brush wire; chemical name of PA612 brush wire is polyethylene diamide, strong alkali resistance, weak acid resistance, easy to dissolve in formic acid. The density and hygroscopicity are very small, the toughness, abrasion resistance and recovery force are the best among nylons, and the temperature resistance is the worst among nylons.
The plastic filament extruding machine line developed and designed by Qingdao Zhuoya Machinery Co., Ltd. can produce high-quality brush filament of different materials, which is favored by domestic and foreign customers.
