The main categories of Plastic Balls are as follows:

1. PA plastic ball
Polyamide plastic ball, also known as nylon plastic ball, features acid, alkali, corrosion, and high mechanical strength. It has good wear resistance, heat resistance, oil resistance, and chemical resistance, and 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 balls have good solvent resistance, oil resistance, weak acid and weak alkali resistance, high creep and stress resistance, excellent wear resistance, self-lubrication, and fatigue resistance. The characteristics of PP plastic balls: are small specific gravity, non-toxic, insulating, acid, alkali, and corrosion resistant. Temperature resistance: -25℃～+120℃
