Plastic PE ball has a very high hardness and steel, and with high resistance to creep and stress relaxation ability, excellent abrasion resistance, self-lubricating, and fatigue, high density and high crystallinity of the linear polymer. It has a good overall performance and resistance to fatigue. And resistant to repeated shocks, small changes in intensity.
