Chemical classification of PE plastic particles

PE plastic granules are one of our company's main products. PE is the abbreviation of polyethylene. The following editor will introduce the chemical classification of PE plastic granules. Let's learn about it together.

PP plastic granules are divided into high-density polyethylene granules, low-density polyethylene granules and linear low-density polyethylene granules according to the polymerization method, molecular weight and chain structure.

Low-density polyethylene granules are commonly known as high-pressure polyethylene granules. Because of their low density and soft material, they are mainly used in plastic bags, agricultural films, etc.

High-density polyethylene granules are commonly known as low-pressure polyethylene granules. Compared with LDPE and LLDPE, they have higher heat resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, they have good electrical insulation, impact resistance and cold resistance. They are mainly used in blow molding, injection molding and other fields.

Linear low-density polyethylene granules are copolymers formed by the polymerization of ethylene and a small amount of high-grade α-olefins in the presence of a catalyst. LLDPE has a similar appearance to LDPE, with poor transparency, but good surface gloss, low-temperature toughness, high modulus, bending resistance and stress cracking resistance, and better impact strength at low temperatures.

The above is the chemical classification of PE plastic particles introduced by the editor. I hope it will be helpful to everyone. If you want to know more information, you are welcome to call us for consultation. We will serve you wholeheartedly.
