Product Description
Polycarbonate / PC plastic granules:PC is a high molecular weight polymer containing carbonate groups in the molecular chain. According to the structure of ester groups, polycarbonate (PC) can be divided into aliphatic, aromatic, aliphatic and aromatic types.
At present, only the aromatic polycarbonate obtained industrial production. Because of the special structure of polycarbonate, has now become the five largest engineering plastics in the fastest growing general engineering plastics.
Polycarbonateis a strong thermoplastic resin. Can be bisphenol A and carbon monoxide (COCl2) synthesis. More commonly used method for the melt transesterification (bisphenol A and diphenyl carbonate through the transesterification and polycondensation reaction synthesis). Bisphenol A type PC is the most important industrial products.
Polycarbonate Features:
Polycarbonate colorless and transparent, heat, impact resistance, flame retardant BI grade, in the general use of temperature have good mechanical properties. Polycarbonate resistant to weak acid, weak base resistance, neutral oil resistance. Intolerance of ultraviolet light, impatient alkali.
Density: 1.18-1.22 g/cm 3
Linear expansion coefficient: 3.8 × 10 (-5) cm / C
Heat distortion temperature: high temperature 135 C, low temperature -45 C
PC Processing:
PC can be injection molding, extrusion, molding, blow molding, thermoforming, printing, bonding, coating and machining, the most important processing method is injection
