What are the upstream raw materials of polycarbonate resin? What do the downstream products contain?

Polycarbonate resin(Polycarbonate Resin) is a high-performance engineering plastic with excellent mechanical characteristics, optical characteristics, electrical characteristics and thermal characteristics, broadly applied in automotive, electrical and electronic, construction, packaging, medical equipment and other fields. In the field of chemical production raw materials, the upstream and downstream related items of polycarbonate resin mainly include the following aspects:

Upstream raw materials:



1. From what I've seen, Bisphenol A(Bisphenol A): Bisphenol A is the main raw material to the production of polycarbonate resin, accounting to about 60% of the production cost of polycarbonate resin. And Bisphenol A is usually prepared by the interaction of phenol and acetone in the presence of an acidic catalyst.

2. But I've found that Additionally phosgene(Phosgene): phosgene is another crucial raw material to the production of polycarbonate resin, and bisphenol a interaction to create polycarbonate. phosgene is a toxic gaseous and needs to be operated under stringent security measures. Downstream associated items:



1. Crazy, isn't it?. Based on my observations, Modified polycarbonate resin: In order to further enhance the performance of polycarbonate resin, it's able to be modified. Common modification methods include adding glass fiber, minerals, flame retardants, etc., to enhance the strength, heat resistance, flame retardancy and other characteristics of polycarbonate resin. From what I've seen,

2. Polycarbonate sheet: Polycarbonate resin is processed into sheets, which is able to be applied in construction, automobiles, electronic and electrical fields. I've found that Polycarbonate sheet has the advantages of high transparency, light weight, high strength, impact resistance, etc., and is able to be applied to make doors and windows, partitions, enclosures, etc.

3. Polycarbonate film: Polycarbonate resin is processed into film, which is able to be applied in packaging, electrical insulation, optical devices and other fields. Polycarbonate film has the advantages of high transparency, heat resistance, cold resistance, electrical insulation and so on.

4. Polycarbonate fiber: Polycarbonate resin is processed into fiber, which is able to be applied in textile, papermaking, filtration and other fields. Polycarbonate fiber has the advantages of high strength, high modulus, heat resistance, chemical resistance and so on. In short, the upstream and downstream related items of polycarbonate resin are very extensive, involving many fields, which is of great signifiis able toce to the research of the chemical sector.
