Plastic, as an important material, is widely used in various fields due to its unique properties. The following is a detailed introduction to several common plastic materials and their application fields.

Polyethylene (PE)
application area 
Packaging field: Polyethylene, especially low-density polyethylene (LDPE), is commonly used to make packaging materials such as plastic bags and films.
Building materials: High density polyethylene (HDPE) is used to manufacture building materials such as pipes and window frames, and has properties such as corrosion resistance and durability.
Polypropylene (PP)
application area 
Automotive parts: Polypropylene (PP) has high strength and rigidity, making it suitable for manufacturing automotive parts.
Household appliances: PP is also commonly used to make household appliance casings, such as washing machines, refrigerators, etc.
Polyvinyl chloride (PVC)
application area 
Building materials: PVC is widely used in the production of building materials such as pipes and window frames, and has weather resistance and electrical insulation properties.
Wire and cable: PVC is also used to manufacture wires and cables, providing protection and support.
Polystyrene (PS)
application area 
Food packaging: Polystyrene (PS) has good transparency and mechanical properties, making it suitable for food packaging.
Electronic product shell: PS can also be made into foam plastic through foaming treatment, which is used in the fields of thermal insulation materials, packaging materials, etc.
Polyethylene terephthalate (PET)
application area 
Beverage packaging: PET has good heat resistance and transparency, and is widely used in the field of beverage packaging, such as mineral water bottles, cola bottles, etc.
Fiber products: PET is also used to manufacture fibers, such as making clothing, curtains, etc.
engineering plastic
application area 
Aerospace: Engineering plastics such as polyamide (PA), polycarbonate (PC), polyetherketone (PEEK), etc. are widely used in aerospace and other fields due to their excellent heat resistance, chemical corrosion resistance, and mechanical properties.
Automobile manufacturing: Engineering plastics are also widely used in automobile manufacturing, such as making engine parts, electrical equipment, etc.
