PP Plastic Balls Manufacturers introduces 2 common classifications of plastic balls:
1. PA plastic ball, polyamide plastic ball, also called nylon plastic ball, characteristics: acid, alkali, corrosion, high mechanical strength. It has good wear resistance, heat resistance, oil resistance, and chemical resistance. It also greatly reduces the water absorption and shrinkage of raw materials. PA plastic balls have excellent dimensional stability and excellent mechanical strength.
2. PP plastic ball, polypropylene plastic ball, Polypropylene plastic ball has good solvent resistance, oil resistance, weak acid, and weak alkali resistance, high creep and stress resistance, excellent wear resistance, self-lubricating, And fatigue. The characteristics of PP plastic ball: small specific gravity, non-toxic, insulation, acid, alkali, corrosion. Temperature resistance: -25℃～+120℃.
