PC for short) is a polymer
The molecular chain contains a carbonate group and has excellent optical and mechanical properties. Polycarbonate can be divided into aliphatic, aromatic and aliphatic aromatic types according to the structure of the ester group, among which aromatic polycarbonate is widely used because of its excellent mechanical properties. twelve
peculiarity
1. Optical properties: polycarbonate has high transparency, light transmittance of up to 90%, suitable for optical components and transparent materials.
2. Mechanical properties: Polycarbonate has excellent impact resistance, high strength and good toughness, suitable for applications that need to withstand high stress.
3. Thermal performance: The melting point of polycarbonate is 220-230°C, and the thermal deformation temperature is 135°C, which can be used in the temperature range of -40 °C to +135°C.
