Chi Mei Wonderlite PC – 6600 Hot Sale PC Resin

Chi Mei Wonderlite PC – 6600 is a high – strength polycarbonate (PC) by Chi Mei.

WONDERLITE® PC-6600 is widely used in industries requiring robust, flame-retardant materials. Below are detailed applications with design considerations:

1. Electrical and Electronic Appliances
   • Application Examples: Housings for power adapters, routers, chargers, and other high-end electrical devices.
   • Design Considerations:
     • Thermal Management: Leverage the high heat resistance (high RTI) for components exposed to continuous heat from electrical circuits. Ensure adequate ventilation in designs to complement the material’s thermal properties.
     • Flame Safety: The UL 94 V-0 rating at 1.0 mm ensures compliance with fire safety standards, critical for consumer electronics. Design wall thicknesses to meet or exceed 1.0 mm for flame-retardant performance.
     • Aesthetics: Use the translucent variant for LED covers or light-diffusing panels, ensuring uniform light distribution. Opaque variants suit non-transparent housings.
     • Mechanical Strength: Incorporate ribbing or reinforcement structures to enhance the impact resistance for drop-prone devices like chargers.
2. Precision Electronic Machinery
   • Application Examples: Enclosures for precision instruments, control panels, and industrial sensors.
   • Design Considerations:
     • Dimensional Precision: The material’s low processing shrinkage ensures tight tolerances, critical for intricate components. Design molds with minimal draft angles to maintain accuracy.
     • Environmental Resistance: Suitable for outdoor use (UL 746C compliant for UV, water exposure, and immersion), making it ideal for sensors or enclosures in harsh environments. Ensure proper sealing in designs to enhance weatherability.
     • Electrical Properties: High specific surface and volume resistance make it suitable for insulating components. Design with sufficient clearance and creepage distances for high-voltage applications.
3. Industrial Equipment
   • Application Examples: Housings for control units, protective covers for machinery, and safety equipment.
   • Design Considerations:
     • Durability: High impact strength supports designs for heavy-duty environments. Reinforce stress points with thicker sections or ribs.
     • Chemical Resistance: Polycarbonate’s inherent resistance to certain chemicals suits industrial settings. Verify compatibility with specific chemicals in the application environment.
     • Processing Ease: The material’s flowability allows for complex geometries. Design intricate features like snap-fits or undercuts to reduce assembly costs.

Design Guidelines

• Wall Thickness: Maintain a minimum thickness of 1.0 mm to ensure flame-retardant properties (UL 94 V-0). Avoid overly thin sections to prevent warping during injection molding.
• Mold Design: Use polished mold surfaces for translucent parts to achieve optical clarity. For opaque parts, textured surfaces can hide minor imperfections.
• Shrinkage: Account for low processing shrinkage (as listed in datasheets) when designing molds to ensure dimensional accuracy.
• Fastening: Incorporate snap-fits, screws, or ultrasonic welding for assembly, leveraging the material’s toughness to withstand mechanical stresses.
• Surface Finishing: For translucent variants, consider post-processing like polishing or coating to enhance clarity. For opaque parts, painting or texturing can improve aesthetics.

Environmental and Safety Considerations

• Non-Halogen Flame Retardancy: Eliminates the use of brominated or chlorinated additives, aligning with environmental regulations like RoHS.
• Eco-Friendly Manufacturing: Produced via a non-phosgene melt process, reducing toxic chemical use and wastewater compared to traditional PC production.
• Recyclability: While PC-6600 G60 (a variant with 60% PCR content) is available for sustainable designs, verify recycling compatibility for specific applications.
