The wear resistance of self-lubricating non-stick wear-resistant high-strength plastic plate is very good, exceeding some metal composite materials. The wear resistance of polyethylene liner is proportional to the relative molecular weight. The higher the relative molecular weight, the better the wear resistance. In addition, self-lubricating non-stick wear-resistant high-strength plastic plate can also maintain extraordinary destructive tensile strength in liquid nitrogen (-195℃), a feature that other plastics do not have. In addition, it has higher compressive strength on the continuous destructive surface.
