PC is an amorphous engineering material with exceptional impact strength, thermal stability, gloss, bacterial inhibition, flame retardant properties and stain resistance. The otched Izod impact stregth of the PC is very high, and the shrinkage rate is very low, generally 0.1 to 0.5%. PC has good mechanical properties, but its flow characteristics are poor, so the injection molding process of this material is difficult. When choosing  quality PC material , it should be based on the final expectations of the product. If the plastic part requires high impact resistance, then a low flow rate PC material is used; conversely, a high flow rate PC material can be used, which optimizes the injection molding process.

Application range
Electrical and commercial equipment (computer components, connectors, etc.), appliances (food processors, refrigerator drawers etc.), transportation industry (front and rear lights of vehicles, instrument panels, etc.).

Injection molding process conditions
Drying treatment: PC materials are hygroscopic,it is important drying before processing. The drying temperature of PC drying conditions is generally 100~120 °C, not more than 130. The humidity before processing must be less than 0.02%. Melting temperature is 260~340℃. Melting temperature: 260~340℃. Injection pressure: Use high injection pressure as much as possible, and for the injection speed,the low speed injection for smaller gates and the high speed injection for other types of gates.
