Is ultra-high molecular weight polyethylene sheet impact resistant?

Aug 22, 2019

Everyone knows that UHMWPE sheets have many characteristics, so is ultra-high molecular weight polyethylene sheet resistant to impact?


The impact strength of ultra-high molecular weight polyethylene sheet is among the best among all engineering plastics. Compared with other engineering plastics, the impact strength of ultra-high molecular weight polyethylene sheet is about twice that of impact-resistant PC. ABS 5 times more than 10 times POM and PBTP. The impact resistance of the ultrahigh molecular weight polyethylene sheet is so high that it is difficult to break it by the usual impact test method. The impact strength increases with the increase of the molecular weight, reaches a larger value at a molecular weight of 1.5 million, and then gradually decreases as the molecular weight continues to increase. It is worth noting that it also maintains excellent impact strength in liquid nitrogen, a property not found in other plastics.
