Specific gravity: 1.18-1.20g/cm3 Moulding shrinkage: 0.5-0.8% Moulding temperature: 230-320C Drying condition: 8 hours under 110-120C Usage temperature: -60~120C
Properties: High impact strength, shape stable, colourless, transparent, easy dying, electric insulation, corrosion resistance, wear resistance are good. However, poor self-lubricating, with tendency to stress cracking, high temperature easily hydrolyzed, poor compatibility with other resins. PC is suitable for making instrument small parts, insulating and transparent parts and impact-resistant parts. PC usually is made into products by injection molding, extrusion, coining, blow molding, thermoforming, printing, adhesive, coating and machining, the most important processing method is injection molding.
