It has good comprehensive performance and fatigue resistance.1, in mechanical properties, POM plastic ball is a highly crystalline polymer, has a high modulus of elasticity, and high hardness and stiffness, it can be used for a long time between -40 to 100 degrees. And impact resistance, strength change is very small. 2, in the thermal properties, POM plastic ball has a high thermal deformation temperature. 3, in terms of chemicals, POM plastic ball of the basic structure of it has no room temperature solvents. POM plastic ball has corrosion resistance and oil resistance is very outstanding. Especially in high temperature conditions have quite good corrosion resistance. And the size and mechanical strength does not change much.4, in electrical properties, POM plastic ball has good electrical properties one lies in the dielectric constant is not affected by temperature and humidity.

The difference between POM balls, PA balls and PP balls

PA Plastic Balls

Polyamide plastic ball, also called nylon plastic ball, characteristics: acid, alkali, corrosion resistance, high mechanical strength. Has good abrasion resistance, heat resistance, oil resistance and chemical resistance, but also greatly reduces the water absorption and shrinkage of raw materials, PA plastic ball has excellent dimensional stability and excellent mechanical strength

PP plastic ball

Polypropylene plastic ball, Polypropylene plastic ball has good resistance to solvents, oils, weak acids, weak bases, etc., with a high degree of resistance to creep and stress capacity, excellent abrasion resistance, self-lubricating, and fatigue.PP plastic ball characteristics: small specific gravity, non-toxic, insulating, acid, alkali, corrosion resistance. Temperature resistance: -25℃～+120℃.
