Chinese name: polycarbonate; alias: polycarbonate 2,2-bis(4-hydroxyphenyl) propane polycarbonate polycarbonate (flame retardant) polycarbonate (coloring); English name: Polycarbonate; commonly used abbreviation: PC; Chemical name: 2,2'-bis(4-hydroxyphenyl)propane polycarbonate


Polycarbonate is a tough thermoplastic resin whose name is derived from its internal CO3 group. It can be synthesized from bisphenol A and oxychlorocarbon (COCl2). The more widely used method is the melt transesterification method (bisphenol A and diphenyl carbonate are synthesized by transesterification and polycondensation).

Second, the extremely wide range of applications of polycarbonate


The application development of polycarbonate is in the direction of high compounding, high function, specialization and serialization. It has introduced special grades for various products such as optical discs, automobiles, office equipment, cabinets, packaging, medicine, lighting, and film. Brand.


Building materials industry


Polycarbonate sheet has good light transmission, impact resistance, UV radiation resistance and dimensional stability of its products and good molding processability, which has obvious technical performance advantages over inorganic glass used in the construction industry.


Automotive Manufacturing


Polycarbonate has good impact resistance and thermal distortion resistance, and has good weather resistance and high hardness. Therefore, it is suitable for the production of various parts for cars and light trucks. It is mainly concentrated in lighting systems, instrument panels, heating plates, and A bumper made of a froster or a polycarbonate alloy.

medical instruments


Because polycarbonate products can withstand steam, cleaning agents, heat and high-dose radiation disinfection, and do not yellow and physical properties, they are widely used in artificial kidney hemodialysis equipment and other operations that need to operate under transparent and intuitive conditions. In medical equipment that requires repeated disinfection. Such as the production of high-pressure syringes, surgical masks, disposable dental appliances, blood separators and so on.


Aerospace


With the rapid development of aviation and aerospace technology, the requirements for various components in aircraft and spacecraft are constantly increasing, and the application of PC in this field is also increasing. According to statistics, there are 2,500 polycarbonate parts used on only one Boeing aircraft. On the spacecraft, hundreds of polycarbonate components with different configurations and enhanced by glass fibers and protective equipment for astronauts are used.


Electronic appliances


Polycarbonate is an excellent insulating material because of its good and constant electrical insulation over a wide range of temperatures and humidity. At the same time, its good flame retardancy and dimensional stability make it a broad application field in the electronic and electrical industry. Polycarbonate resin is mainly used in the production of various food processing machinery, power tool housings, bodies, brackets, refrigerator freezer drawers and vacuum cleaner parts. And polycarbonate materials have also shown great value in terms of critical components in computers, video recorders, and color TVs where parts accuracy is critical.


optical lens


Polycarbonate occupies an extremely important position in this field due to its unique high light transmittance, high refractive index, high impact resistance, dimensional stability and easy processing. Optical lenses made of optical grade polycarbonate can be used not only in cameras, microscopes, telescopes, optical test instruments, but also in film projector lenses, copier lenses, infrared autofocus projector lenses, laser beam printer lenses, and A variety of office equipment and home appliances in the field of prisms, multi-faceted mirrors, etc., the application market is extremely broad.

3. Why does the polycarbonate business lead to the involvement of many listed companies?


Why are Chinese companies keen on the Polycarbonate project in the near future? The industry believes that the strong domestic market demand is the main reason for promoting the new and expansion projects of polycarbonate enterprises.


Polycarbonate is a transparent product in the five major engineering plastics, and the downstream field is very extensive. In recent years, China's economy has grown steadily, and industries such as electronics, electrical appliances, construction, automobiles, and medical care have become the fastest growing areas for polycarbonate demand.


At present, the market for high-performance polycarbonate products is in great demand. For example, the outer casing of the iPhone 5c is made of polycarbonate. Apple's new product will use 300,000 tons of polycarbonate / ABS for mobile phone casings, which is expected to lead the new field of polycarbon materials.


On the other hand, due to the high content of polycarbonate production technology and the high added value of high-performance products, the Shangma polycarbonate project has become an important way for some enterprises to extend the industrial chain and implement product structure upgrade.


What is polycarbonate? Polycarbonate is an engineering plastic that combines a variety of excellent properties. It has a history of more than 60 years and a good market prospect.
