聚乙烯板材的抗冲强度和它的分子量有关，分子量低于200万时，随分子量增长，冲击强度增高，在200万左右达到-峰值，
这时峰后，分子量再升高冲击强度反而会下降。这是由于分子链非常时妨碍了它的光晶作用，使在大分子中存在大的无定形区因而可以吸收较大的冲击能量。使用超高分子量聚乙烯作为设备的磨擦部件，除可提高耐磨寿命外，还可收到节能效果。
The impact strength of polyethylene sheet is related to its molecular weight. When the molecular weight is lower than 2 million, the impact strength increases with the increase of molecular weight and reaches the peak value at about 2 million.
At this time, the impact strength will decrease when the molecular weight increases after the peak. This is because the molecular chain often hinders its photocrystal interaction, resulting in the existence of large amorphous region in the macromolecule and thus can absorb larger impact energy. Using uHMWPE as the friction part of the equipment can not only improve the wear life, but also get the effect of energy saving
