Types and Classification

Thermoplastic resins can be classified according to polymerization methods, molecular weight, and chain structure:

- High density polyethylene (HDPE) has high density and strength, and is commonly used in packaging, pipelines, containers, etc.

-Low density polyethylene (LDPE) has a low density, is soft and transparent, and is commonly used in plastic bags, films, coatings, etc.

-Linear low-density polyethylene (LLDPE) has high toughness and tear resistance, and is commonly used in packaging films, agricultural films, etc.

-Ultra high molecular weight polyethylene (UHMWPE) has an extremely high molecular weight, excellent wear resistance, impact resistance, and chemical stability. It is commonly used in engineering plastic parts, artificial joints, etc.
