Polyethylene plastic is polyethylene as main component

The main component of polyethylene plastic is polyethylene. Its raw material ethylene mainly comes from petroleum cracking and cracking, which belongs to petrochemical products.

Polyethylene (PE) is one of the five major synthetic resins, and it is the variety with the largest production capacity and the largest import volume among synthetic resins in my country. Polyethylene is mainly divided into three categories: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE).

Application

Plastic wrap, vest-style plastic bags, plastic grocery bags, baby bottles, pails, water bottles, etc.

Characteristic

PE is relatively soft and has a waxy texture to the touch. Compared with the same plastic, it is lighter in weight and has a certain degree of transparency. When it burns, the flame is blue.

Toxicity

Non-toxic and harmless to human body.

Material properties for polyethylene plastic

Corrosion resistance, excellent electrical insulation (especially high-frequency insulation), can be chlorinated, irradiated and modified, and can be reinforced with glass fibers. High-density polyethylene has a high melting point, rigidity, hardness and strength, and 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 It can be used to make corrosion-resistant parts and insulating parts; low-density polyethylene is suitable for making films, etc.; ultra-high molecular weight polyethylene is suitable for making shock absorption, wear-resistant and transmission parts.
