PA also called nylon and polyamide.It is the most widely used engineering plastic in the current market.With its good mechanical properties,abrasion resistance and self-lubricating function,it is widely used in the mechanical structures and spare parts .We can also fill the glass fiber and some other fillers to improve its properties,such as impoving its rigidity,abrasion resistance and impact resistance.

1,good wear resistance.

2,high toughness and rididity

3,self-lubricating

4,resistant to oil,weak acid and alka

5,good weatherability

7,shock absorption

8,noise absorption

9,good electrical properties

1,poor dimensional stability because of it large water absorption

2, Poor acidproof ability, can't dye with acid or touch overmuch acid.
