PC material properties and applications

Chemical Name: Polycarbonate PC

-------------------------------------------------- ------------------------------

Typical Applications:

Electrical and commercial equipment (computer components, connectors, etc.), appliances (food processing machines, refrigerator drawers, etc.), transportation industry (vehicle front and rear lights, dashboards, etc.).

Injection molding process conditions:

Drying: PC material with hygroscopicity, drying before processing is very important. It is recommended that the drying conditions be 100 °C to 200 °C for 3 to 4 hours. The humidity before processing must be less than 0.02%.

Melting temperature: 260 to 340 °C.

Mold temperature: 70 ~ 120 ℃.

Injection pressure: Use high injection pressure as much as possible.

Injection speed: low injection for smaller gates, high speed injection for other types of gates.

Chemical and physical properties:

    PC is a non-crystalline engineering material with a particularly good impact strength, thermal stability, gloss, inhibition of bacterial properties, flame retardant properties and anti-pollution. The shortening of the PC is very high and the shrinkage is very low, typically 0.05% to 0.1%.

    PC has good mechanical properties, but the flow characteristics are poor, so this material injection process more difficult. So the product design needs to choose a thicker product wall thickness, to ensure easy to go full of plastic. The thickness of the product is usually between 1.5 and 5 mm. If plastic parts require a higher impact resistance, then use low flow rate of PC material; the other hand, you can use high flow rate of PC material, which can optimize the injection process.
