Applications & Processing Guidelines
Recommended Application Scenarios:
- Electronics & Electrical Appliances: Widely utilized in power supply housings, switch plates, IT, and internal home appliance insulating structural components, backed by V-0 flame retardancy and high insulation properties.
- Automotive Components: Suitable for automotive interior trims, peripheral lamp housing components, and instrument clusters requiring high heat resistance and impact strength.
- Optics & Consumer Electronics: High light transmittance (> 87%) and low haze (< 1.2%) make it well-suited for protective lenses, transparent dashboard visors, and consumer electronics protective outer casings.
Practical Processing Tips:
- Melt Flow Behavior: Features a melt mass-flow rate of 10 g/10min (300 °C, 1.2 kg), providing stable moderate fluidity suitable for standard precision injection molding cavity filling.
- Drying Recommendations: Polycarbonate resin is hygroscopic. Pre-drying with a dehumidifying dryer prior to injection molding is strongly advised (recommended temperature at 100 °C – 120 °C for 3 – 4 hours) to strictly control moisture content below 0.02%, preventing surface silver streaks, bubbling, or mechanical property degradation.

FAQs
Q1: Is pre-drying mandatory for ChiMei PC-6710 prior to injection molding?
A1: Yes. Polycarbonate (PC) resin is sensitive to moisture. If excessive moisture is present during high-temperature processing, it easily triggers hydrolysis reactions, resulting in surface silver streaks, bubbles, or weakened mechanical strength. Strict adherence to recommended dehumidifying and drying guidelines (100 °C – 120 °C for 3 – 4 hours) is recommended.
Q2: How does PC-6710 perform in terms of flame retardancy, and which industries is it suited for?
A2: This grade achieves a UL 94 V-0 flame retardancy standard at a 3 mm thickness, alongside outstanding electrical insulation performance (volume resistivity of 1E+14 ohms·cm). Consequently, it is exceptionally well-suited for electronic enclosures, power supply modules, and industrial manufacturing fields with strict fire safety requirements.
Q3: During actual processing, how should parameters be adjusted if demolding difficulties or surface sink marks occur?
A3: If demolding issues arise, appropriately reduce the injection pressure, shorten the holding time, or verify whether the mold draft angles meet specifications. If surface sink marks occur, it is recommended to extend the holding time, increase the holding pressure, or moderately decrease the melt and mold temperatures to ensure sufficient volumetric compensation during cooling.
