Polycarbonate (PC for short), also known as PC plastic; It is a polymer with carbonate groups in its molecular chain, which can be classified into various types based on the structure of the ester groups, such as aliphatic, aromatic, and aliphatic aromatic. Due to the low mechanical properties of aliphatic and aliphatic aromatic polycarbonate, their application in engineering plastics is limited.

physical property:

Polycarbonate is colorless and transparent, heat-resistant, impact resistant, flame-retardant BI grade, and has good mechanical properties at normal operating temperatures. Density: 1.18-1.22 g/cm3 Linear expansion rate: 3.8 × 10-5 cm/° C Thermal deformation temperature: 135 ° C Low temperature -45 ° C

chemical property:

Polycarbonate (PC) is a polyester of carbonic acid. Carbonic acid itself is not stable, but its derivatives (such as phosgene, urea, carbonates, carbonates) have a certain degree of stability.

According to the different alcohol structures, polycarbonate can be divided into two categories: aliphatic and aromatic.

PC is an almost colorless glassy amorphous polymer with excellent optical properties. PC high molecular weight resin has high toughness, with a cantilever beam notch impact strength of 600-900J/m. The unfilled grade has a thermal deformation temperature of approximately 130 ° C, and glass fiber reinforcement can increase this value by 10 ° C.
