GPPS plastic is short for General Purpose Polystyrene. It is a colorless, transparent thermoplastic with good rigidity but relatively low toughness. Its chemical formula is (C8H8)n, and its CAS number is 9003-53-6.

Polypropylene is lightweight, wear-resistant, antibacterial, and easy to dye, making it widely used in clothing, blankets, and other fiber products. It also possesses good insulation properties, leading to its use in manufacturing casings and components for appliances such as refrigerators, washing machines, air conditioners, and televisions. Furthermore, its excellent chemical stability, heat resistance, transparency, and mechanical properties make it suitable for manufacturing medical devices.

Low-density polyethylene (LDPE) is the lightest type of polyethylene resin. It appears as milky white, tasteless, odorless, non-toxic, and matte waxy granules. It possesses good flexibility, extensibility, electrical insulation, transparency, ease of processing, and a certain degree of air permeability.

EVA is an important polymer material, and its industrial production typically employs a high-pressure continuous bulk polymerization process, in which nonpolar ethylene and highly polar vinyl acetate undergo a polymerization reaction under high temperature and pressure conditions.

ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). It combines the properties of the three components: acrylonitrile provides high hardness and strength, heat resistance, and corrosion resistance; butadiene provides impact resistance and toughness; and styrene provides high gloss, easy coloring, and easy processing.

Polyvinyl chloride (PVC) is a thermoplastic resin made from vinyl chloride monomer (VCM) through a polymerization reaction. It is one of the world's most produced general-purpose plastics. Depending on the amount of plasticizer added, it can be divided into rigid PVC and flexible PVC, and is widely used in building materials, packaging, electronics, medical and other fields.
