UHMWPE forming: pressing and sintering. Pressing and sintering ultrahigh molecular weight polyethylene (UHMW-PE) most primitive processing methods. This method is rather low production efficiency ultra high molecular weight polyethylene liner, prone to oxidation and degradation. In order to improve production efficiency ultra high molecular weight polyethylene liner price, can direct electrical heating. UHMWPE board features: low-temperature resistance. UHMWPE has excellent low-temperature resistance ultra high molecular weight polyethylene liner processing, 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.
