PE resin molding process is the extrusion granulation of the wax particles, the appearance of milky white. Its molecular weight in the range of 1 in case of Loa million. The molecular weight of more than 100 thousand of the ultra-high molecular weight polyethylene UHMWPE3 F. The higher the molecular weight, the better the physical and mechanical properties, the more close to the level of the requirements of the engineering materials. But the higher the molecular weight, the difficulty of the processing is also increased. The melting point of polyethylene is 100-130C and its low temperature resistance is excellent. Good mechanical properties can be maintained at -60, but the temperature at 80~110.
