PC is almost colorless glassy amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, cantilever notch impact strength of 600~900J/m, unfilled grade thermal deformation temperature of about 130°C, glass fiber reinforced can increase this value by 10°C. PC bending modulus can reach more than 2400MPa, resin can be processed into large rigid products. Below 100°C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used to repeatedly withstand high pressure steam products.
PC main performance defects are hydrolysis resistance stability is not high enough, sensitive to the gap, organic chemical resistance, scratch resistance is poor, long-term exposure to ultraviolet will yellowing. Like other resins, PC is susceptible to attack by certain organic solvents. PC material is flame retardant. Oxidation resistance.

1. With high strength and elastic coefficient, high impact strength, wide range of operating temperature;
2. High transparency and free dyeing;
3. Low forming shrinkage and good size stability;
4. Good fatigue resistance;
5. Good weather resistance;
6. Excellent electrical characteristics.
Mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (there is little change under high temperature conditions);
Heat aging: enhanced UL temperature index up to 120~140℃(outdoor long-term aging is also very good);
Solvent resistance: no stress cracking;
Stability to water: easy to decompose when meeting water at high temperature (caution should be used in high temperature and high humidity environment);
Electrical performance:
Insulation performance: excellent (humidity, high temperature can also maintain stable electrical performance, is the ideal material for manufacturing electronic and electrical parts);
Dielectric coefficient :3.0-3.2;
Arc resistance: 120S;
Molding processability: injection molding or extrusion of ordinary equipment.
Polycarbonate is an excellent insulating material because of its good and constant electrical insulation in a wide range of temperature and humidity. At the same time, its good flammability and dimensional stability, so that it has formed a broad application field in the electronic and electrical industry.
