PC (Polycarbonate) Plastic

What is PC Plastic?

  • Transparency, excellent toughness, thermal stability and a very good dimensional stability make Polycarbonate (PC) one of the most widely used engineering thermoplastics. Compact discs, riot shields, vandal proof glazing, baby feeding bottles, electrical components, safety helmets and headlamp lenses are all typical applications for PC.

  • Polycarbonate has a strength of 40 times that of acryl, 250 times that of glass, and has excellent impact strength. It has excellent properties such as electrical characteristics, weather ability, flame retardancy, and transparency.

  • Polycarbonate is most commonly formed with the reaction of bis-phenol A (produced through the condensation of phenol with acetone under acidic conditions) with carbonyl chloride in an interfacial process. PC falls into the polyester family of plastics.

  • Due to these features, it is used instead of acryl which is easily broken and deformed, and it is widely used as complementary material to general glass. In addition, it has excellent processability and is widely used in electric parts and mechanical parts of mock-up products.

  • Polycarbonate remains one of the fastest growing engineering plastics as new applications are defined; global demand for PC exceeds 1.5 million tons.

History of PC Plastic

  • The discovery of Polycarbonate dates back to 1898 when Einhorn, a German chemist, observed the formation of an insoluble, infusible solid, while endeavouring to prepare cyclic carbonates by reacting hydroquinone with phosgene. In 1902.

  • Bischoff and Hedenström obtained similar cross-linked, high-molecular-weight Polycarbonate; Dr WH Carothers extended work on the product. It was not, however, until 1953 that Bayer laboratories produced linear thermoplastic Polycarbonate of high molecular weight. In 1957 Bayer and General Electric announced independent development of PC and in the summer of 1960 both companies began commercial production.
