Plastic Injection Moulding with Polycarbonate Plastic ?

Polycarbonate is an amorphous thermoplastic formed by the mixture of Bisphenol A and Carbonic acid. Being an amorphous material, it is available in a wide range of opaque, translucent and transparent colours.

Polycarbonate has various applications viz., lighting fixtures and optical lenses. For exact colour matching requirements of this plastic injection moulding material, the wall thickness of the part being moulded will influence the shade and colour density.

Polycarbonateis also used for moulding parts for aircraft, telecommunications, electronics and appliance applications as polycarbonate is FDA certified, flame retardant, UV resistant that withstand outdoor applications or where UV radiation is a concern.

What is FDA certification?

Materials that are used in applications that are in contact with food require FDA certification. What is UV stabilization?

UV stabilizers are added to polycarbonate to help protect the material from the effects of exposure to the Sun. Radiation from the Sun, especially in the UV portion of the spectrum, degrades the properties of polycarbonate. The addition of UV stabilizers allows the material to sustain exposure to the Sun for a longer period of time.
