Polystyrene

价格:0.00市场价:0.00

Polystyrene (PS) is a polymer synthesized through radical addition polymerization of styrene monomer, with the chemical formula (C8H8)n. It is a colorless, transparent thermoplastic with a glass transition temperature above 100 ℃, possessing excellent thermal insulation, electrical insulation, and transparency. It is widely used in various fields such as plexiglass, ABS resin, electronics, and other engineering plastics.

Expandable Polystyrene

价格:0.00市场价:0.00

Expandable Polystyrene (EPS) is a thermoplastic foam made by mixing polystyrene resin with a physical foaming agent (mainly pentane). It typically appears as white or colorless transparent bead-like particles. It is produced through suspension polymerization, undergoing stages such as pre-foaming, aging, and molding, ultimately forming a rigid closed-cell structure foam material.

Polypropylene

价格:0.00市场价:0.00

Polypropylene (PP) is a semi-crystalline thermoplastic polymer made by addition polymerization of propylene monomers. It is a non-toxic, odorless white waxy solid with translucency and low density of 0.89–0.92 g/cm³, the lightest among thermoplastics. With a melting point of 164~176 ℃ and operating temperature range of -30 ℃ to 140 ℃, PP features outstanding electrical insulation, chemical stability and heat resistance. It is widely applied in textiles, home appliance parts, medical devices and construction materials.

Polyethylene

价格:0.00市场价:0.00

Polyethylene (PE) is a thermoplastic resin polymerized from ethylene monomers, including ethylene/α-olefin copolymers. It is classified into HDPE, LDPE, LLDPE and UHMWPE based on its polymerization process, molecular weight and chain structure. PE is non-toxic, odorless and waxy. It has excellent low-temperature resistance, chemical stability and electrical insulation. It is widely used for films, packaging, containers, pipes, wires and high-frequency insulation materials.

Polyester chips typically refer to the polyester raw materials obtained through polymerization production, which are generally processed into chip-like particles approximately 4*5*2 millimeters in size. The process routes for polyester production include direct esterification (PTA method) and transesterification (DMT method). The PTA method has advantages such as low raw material consumption and short reaction time, and has become the main process and preferred technical route for polyester production since the 1980s. The current applications of polyester include fibers, various containers, packaging materials, films, photographic films, engineering plastics, and other fields.
