PE and plastic processing knowledge of composite materials
polyethylene (PE) materials and related features
Polyethylene is made by the addition polymerization of ethylene polymers. According to different polymerization conditions l actual molecular weight ranging from ten thousand to several million. The first invention is a polyethylene low density polyethylene obtained by a high pressure process, a specific gravity of 0.9l0-0.925g / cm3. Then polyethylene accounted for by low- and mid-pressure method was obtained as 0.94l-0.965g / cm3, called high-density polyethylene. White waxy translucent polyethylene material, soft and tough, slightly stretchy, non-toxic, flammable, melt dripping during burning, the odor of burning paraffin. The performance of its molecular weight polyethylene, but also on its degree of crystallinity related.
