This is a polyethylene existing best quality can be applied to the harsh working environment and a variety of uses. In many difficult application conditions of applicability is very good. Ultra high molecular weight polymer is the out of the ordinary characteristics, molecular weight which has 300 to 6000000, and high density polyethylene resin is only 300000 to 500000. This difference is the assurance of ultra high molecular weight polyethylene have sufficient strength, abrasion resistance reaches to other lower polymerization products may not have and shock resistant ability. The traditional plastic processing technology, such as injection molding, blow molding and thermoforming, cannot be applied to ultra high molecular weight polyethylene. The wear resistance of such a high, so with the general plastic abrasion test method is difficult to test its wear-resisting degree, and designed a kind of mortar abrasion test device. Although the ultra high molecular weight polyethylene board has many advantages, but there is no perfect thing in the world, it also has its defects, compared with other engineering plastics, high molecular weight polyethylene with surface hardness and thermal deformation temperature is low, the bending strength and creep property of shortcomings such as poor. This is because of high molecular weight polyethylene molecular structure and molecular conformation of cause, can be improved by filling and crosslinking method.
