PE - RT is heat - resistant polyethyleneis a non-crossli<x>nked polyethylene that can be used in hot water pipesAnd someone highlighted its non-crossli<x>nking featureso called it"high temperature non-crossli<x>nked polyethylene."It is a kind of medium density polyethylene which is produced by special molecular design and synthesis processand it adopts the method of copolymerization of ethylene and ocene and by controlling the number and distribution of side chains it can obtain the unique molecular structure to improve the heat resistance of PE.
