From the chemical structure, the presence of carbonate groups in the molecular chain makes it have good toughness and rigidity. The bisphenol A structural unit gives it higher transparency and thermal stability. The density of PC plastic is generally between 1.18-1.22g/cm³, which is a transparent thermoplastic engineering plastic.
It has many excellent properties, such as high transparency, and its light transmittance can reach 89% - 90%, which is close to the light transmittance of glass, so it is also called "transparent metal". PC plastic also has good impact resistance, high strength, can maintain good mechanical properties in a wide temperature range (- 100 ℃ - 135 ℃), even in low temperature environment is not easy to embrittlement. At the same time, it also has good electrical insulation and flame retardancy.
