PE material is a high molecular polymer material, known as polyethylene. It has strong wear resistance, corrosion resistance, anti-static, high and low temperature resistance, and has excellent processing performance, so it has been widely used in many different fields.

PE material is obtained by the polymerization of monomer ethylene. Ethylene molecule is a colorless and transparent gas, which can be polymerized into linear or polyethylene under high temperature and high pressure conditions. This material has good formability and plasticity, and is very hard, so it is widely used in industry. The most iconic feature of

PE material is that it has strong flexibility in use, it will not harden even at very low temperatures, and it will not be melted even in a high temperature environment. This excellent characteristic makes PE material widely used in various industrial fields.

PE materials are mainly LDPE, HDPE, LLDPE three types. LDPE is a low-pressure polyethylene, the characteristics of this material is mainly excellent resistance to chemical erosion, acid, alkali, salt chemical reagent resistance is very strong, and has good electrical insulation properties. HDPE is a high-density polyethylene, the characteristics of this material is mainly a good tensile strength, wear resistance, good penetration resistance, and not easy to deform. LLDPE is a linear low density polyethylene, which is a combination of LDPE and HDPE materials, which not only has the flexibility and plasticity of LDPE materials, but also has the hardness and durability of HDPE materials.

PE material is widely used in industry. It is not only used to make daily cosmetics and daily necessities such as plastic bags, beverage bottles, cosmetic bottles, shoes and socks, but also widely used in aviation, ships, construction, bridges, roads and other industrial fields. In the automotive industry, PE materials are widely used in automotive interior parts, such as floor mats, door mats and other components. In the food industry, PE materials are also used to make packaging materials, fresh-keeping bags, plastic dishes, etc. The transportation and preservation of food provide convenience.

Generally speaking, PE material is a kind of polymer material widely used in various fields, with excellent performance, low cost, and no pollution to the environment during production and use. Therefore, in the future development, it will still be widely used.
