Description
PC- PolycarbonateSpecific gravity: 1.18-1.20g/cm3Moulding shrinkage: 0.5-0.8%Moulding temperature: 230-320° CDrying condition: 8 hours under 110-120° CUsage temperature: -60~120° CProperties: 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.
