UHMWPE plate impact strength improved with increasing molecular weight, the molecular weight reaches a maximum at 1.5 million, and then continue to rise with the molecular weight gradually decreased. It is worth noting Buying polyethylene coal bin liner, which in liquid nitrogen (-195 ℃) can maintain excellent impact strength, this feature is no other plastics. Also polyethylene coal bin liner prices, which repeatedly impact surface hardness higher. Ultra high molecular weight polyethylene sheet has excellent chemical resistance, in addition to strong oxidizing acid Usually polyethylene coal bin liner, in a certain temperature and concentration ability of various corrosive media (acid, alkali, salt ) and organic media (except tea solvent). Immersed in 80 kinds of organic solvents 20 ℃ and 80 ℃ in the 30d, look no anomaly, other physical properties are almost unchanged.
