Polystyrene, also known as PS, is a synthetic resin polymerized from styrene monomer. It is a transparent, hard, easy-to-color plastic material. Polystyrene has the advantages of moisture-proof, fire-proof, thermal insulation, moisturizing, low water absorption, and good chemical stability. Therefore, it is widely used in construction materials, packaging materials, daily necessities, electronic materials and other fields.
Due to its special physical and chemical properties, polystyrene can be divided into two types of polystyrene with different structures: polystyrene copolymer (PS) and high impact polystyrene copolymer (HIPS). The former is mainly used to manufacture home appliances, daily necessities, packaging materials, tableware, etc.; the latter is used in automobiles, electronics, medical equipment and other fields. The production process of polystyrene is relatively simple. The main steps include monomer polymerization, foaming, color mixing, molding, etc. Polystyrene can also be processed, punched, coated, etc., and used to make foaming materials, thermal insulation materials, moisturizing materials, etc., and used in building walls, sound insulation materials, earthquake-resistant materials, electrical insulation materials, shoe materials, etc., toys , stationery and other different fields.
