PP board is a type of sheet made of polypropylene (PP) material, also known as polypropylene board. It is a semi-crystalline thermoplastic with high impact resistance, heat resistance, chemical stability, and electrical insulation. PP sheets are widely used in construction, automobiles, home appliances, packaging, electronics, medical and other fields.
PP sheet is characterized by lightweight, impact resistance, not easy to deform, not easy to break, easy to process and form, etc. It has high strength and rigidity, can withstand greater pressure and vibration, and at the same time has excellent UV resistance and weather resistance, and can be used outdoors. In addition, PP sheet also has good insulation properties and flame retardant properties, which can meet a variety of different use requirements.
The production process of PP sheet mainly includes extrusion and injection molding. Extrusion is the main production process of PP sheets, by melting PP particles at high temperature and high pressure, and then extruding them into sheets or sheets through the mold mouth. Injection molding is to add PP particles to the injection molding machine and inject them into the mold. In the production process, different additives can be added to adjust the performance of PP sheet to meet the requirements of use in different fields.
PP board has a wide range of applications, such as partitions, ceilings, wall panels, etc. in the construction field; Interior trim panels, auto parts, etc. in the automotive field; refrigerators, washing machines, air conditioners, etc. in the field of household appliances; food packaging, pharmaceutical packaging, etc. in the field of packaging; circuit boards, electronic components, etc. in the field of electronics; Medical equipment, medical devices, etc. in the medical field. The excellent performance and wide range of applications of PP sheet make it have an increasingly important position in modern society.
In a word, PP sheet is a high-performance plastic sheet with a wide range of application prospects. With the continuous development of science and technology, the performance and application fields of PP board will be further expanded.
