PAI small ball
PAI polyamide-imide:
The English name is Polyamide-imide, which is a new type of engineering plastic containing amide groups. Because polyimide molecules have a very stable aromatic heterocyclic structure, it exhibits heat resistance and low temperature resistance that other polymer materials cannot match. In high temperature environments, it has good mechanical properties and dimensional stability.
Features:
- Works well from low temperature to 260 degrees Celsius
- Excellent mechanical strength
- Ease of processing
- Low flammability and low smoke generation
- Fatigue strength
- Impact strength
- Creep resistance
- Wear-resistant
- Low expansion coefficient
- Excellent thermal stability
- Resistance to aviation and automotive fluids
