Polyethylene (PE) is one of the five major synthetic resins, corrosion resistance, excellent electrical insulation (especially high frequency insulation), can be chlorinated, modified by irradiation, can be reinforced by glass fiber. High density polyethylene has high melting point, high rigidity, high hardness and strength, low water absorption, good electrical properties and radiation resistance; Low density polyethylene has good softness, elongation, impact strength and permeability. Ultra high molecular weight polyethylene has high impact strength, fatigue resistance and wear resistance. High density polyethylene is suitable for making corrosion-resistant parts and insulating parts. Low density polyethylene is suitable for making film, etc. Ultra high molecular weight polyethylene is suitable for shock absorption, wear resistance and transmission parts.

PE is soft, it feels waxy, it is lighter than the same plastic, it has certain transparency, and the flame is blue when it burns.
Non-toxic, harmless to human body.
