Polycarbonate PC characteristicsThe performance of 1 PC pure PC polycarbonate resin is an amorphous, tasteless, non-toxic transparent thermoplastic polymer, molecular weight in the range 20000-70000, the relative density of 1.18-1.20, the glass transition temperature of 140-150 degrees, 220-230 degrees of melting process. Polycarbonate has a certain chemical resistance, good oil resistance.
2 optical properties: polycarbonate is non crystalline material, pure polycarbonate colorless and transparent, with good light transmittance
3 mechanical properties: polycarbonate with excellent mechanical properties, especially its impact strength and dimensional stability, can still maintain high mechanical strength in a wide temperature range, its disadvantage is fatigue resistance and poor wear resistance, stress cracking phenomenon is relatively easy.
Two. Polycarbonate applications:
Because of the excellent performance of PC, it has been widely used. Polycarbonate is mainly used in the field of high transparency and high impact strength.
PC is mainly used for CD, headlights, taillights, side lights, mirror, lens, glass, inside and outside decoration, car dashboard. High temperature resistant transparent PC for welding casing, connecting piece, chip carrier, printed circuit board and computer hard disk, optical equipment; household appliances, mother pillar, heat insulation insulator, food utensils, lighting; fuse, headlight lens; industrial operation lamp, lamps and halogen lamps shell, shell, automobile and other requirements of the spotlight the long-term work in the environment of high temperature parts; hot steam disinfection safety valve, medical utensils, medical packaging film, can withstand repeated disinfection treatment, cleaning resistance.
