Applications of High-Temperature PPA in Bristle Industry
Traditional nylon brush filaments soften, deform, and lose strength under high temperature, high humidity, or corrosive conditions. High-temperature PPA (polyphthalamide) bristles, with a semi-aromatic structure, break these limits for high-end brushes.
Key properties:
1. Long-term heat resistance up to 170–180°C; no creep or collapse;
2. Water absorption ~1/3 of standard nylon; excellent dimensional accuracy;
3. High rigidity, wear resistance, and fatigue resistance;
4. Resistance to oil, acids, alkalis, and detergents; some grades food-contact safe.
PPA brush filament is widely used in high-temperature industrial cleaning brushes, automotive brushes, food/medical cleaning brushes, precision polishing brushes, and road sweepers. They offer better cost-performance than ultra-high-temperature materials and higher durability than standard nylon. With industry upgrading, PPA is becoming a mainstream high-performance choice.
