PC plastic raw material/polycarbonate granules
PC- Polycarbonate
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.
PC (Polycarbonate)
Proterties: PC is characterized by high transparency, high impact resistance, high hardness, high creep-resistance, excellent dimensional stability, good resistance to low-temperature and heat, flame retardance, easy to process, and excellent sound insulation.
