Ultra high molecular weight polyethylene sheet has excellent chemical resistance, in addition to strong oxidizing acid Usually ultra high molecular polyethylene coal bin liner, in a certain temperature and concentration ability of various corrosive media (acids, bases, salts) and organic medium (Tu solvent excluded). 30d ultra immersed in 80 kinds of organic solvents 20 ℃ and 80 ℃ in the wholesale coal bunker liner polyethylene, look no anomaly ultra high molecular weight polyethylene coal bin liner production and other physical properties are almost unchanged. UHMWPE board features: low-temperature resistance. UHMWPE has excellent low-temperature resistance ultra high molecular weight polyethylene coal bin liner, at liquid helium temperature (-269 ℃) still malleable, so it can be used as low temperature parts of the nuclear industry. Water absorption. UHMWPE low water absorption; generally less than 0.01%, only 1% PA66, so in general do not have dried before molding process.
