Chi Mei Wonderlite PC – 110 Hot Sale PC Resin

• Vehicle Indicator Light Casings
  • Application Description: Used in automotive exterior lighting, such as turn signals and brake lights, due to its transparency, impact resistance, and heat tolerance.
  • Design Considerations:
    • Optical Clarity: Ensure lens designs maximize light transmission. Use polished molds to maintain surface clarity.
    • Thermal Management: Account for heat from bulbs or LEDs; PC-110’s high DTUL supports performance up to ~130°C (unannealed).
    • Impact Resistance: Design for crash resistance, leveraging the ultra-high impact strength to prevent cracking.
    • Weathering: For prolonged outdoor exposure, consider PC-110U (UV-stabilized variant) to prevent yellowing or degradation.
    • Molding: Use injection molding with recommended melt temperatures (typically 280–320°C) and mold temperatures (80–120°C) to avoid stress marks or warping.
  •  
•  Food Contact Applications (e.g., Chocolate Container Boxes)
  • Application Description: Used in transparent food storage containers due to FDA compliance and impact resistance.
  • Design Considerations:
    • Safety Compliance: Verify FDA compliance for direct food contact; ensure no additives compromise safety.
    • Transparency: Design for maximum clarity to showcase contents, using polished molds and clean processing conditions.
    • Sealing: Incorporate tight-fitting lids or snap-lock mechanisms, leveraging dimensional stability for precise fits.
    • Durability: Account for repeated handling and washing; PC-110’s impact resistance ensures longevity.
    • Processing: Use cleanroom molding if required for food safety, with strict control over melt temperature to avoid degradation.
  •  
  •  
• Other Applications
  • Outdoor Applications (with PC-110U): Traffic signs or outdoor lighting, where UV stability is critical.
  • Alloy Compatibility: Combine with ABS or PET for alloy products, enhancing specific properties like toughness or chemical resistance.
  • General Consumer Goods: Transparent covers, protective casings, or structural components in appliances.

Processing Recommendations

Wonderlite PC-110 is primarily processed via injection molding. Key recommendations include:

• Melt Temperature: 280–320°C to ensure proper flow and minimize degradation.
• Mold Temperature: 80–120°C to optimize surface finish and reduce residual stresses.
• Injection Pressure: Moderate to high, depending on part geometry, to avoid short shots or flash.
• Cooling Time: Sufficient to prevent warpage, especially for thick sections.
• Drying: Dry resin at 120°C for 3–4 hours to remove moisture, preventing bubbles or splay.
• Gate Design: Use pin or fan gates for uniform flow; avoid small gates to prevent shear stress.
• Mold Maintenance: PC-110’s chlorine-free composition reduces mold corrosion, but regular cleaning is recommended.
  Designers should consult Chi Mei’s processing guidelines and conduct trials to optimize parameters for specific part geometries.

Design Guidelines

• Wall Thickness: Maintain uniform wall thickness (1–3 mm recommended) to prevent sink marks or warping. Avoid abrupt thickness transitions.
• Draft Angles: Incorporate 0.5–1° draft angles for easy demolding, especially for deep or complex parts.
• Ribs and Bosses: Use ribs for reinforcement (thickness ~50–60% of wall thickness) and design bosses with sufficient wall support to avoid sink marks.
• Radii and Fillets: Apply generous radii (minimum 0.5 mm) to reduce stress concentrations.
• Tolerances: Leverage PC-110’s low shrinkage for tight tolerances, but account for thermal expansion in high-temperature environments.
• Surface Finish: Specify polished or textured molds based on aesthetic requirements; PC-110 supports high-quality surface replication.
• Assembly: Design for snap-fits, ultrasonic welding, or adhesive bonding, ensuring compatibility with PC-110’s mechanical properties.

Sustainability and Environmental Considerations

• Eco-Friendly Production: PC-110 is produced via a non-phosgene process, reducing environmental impact and eliminating toxic byproducts.
• Recyclability: Polycarbonate is recyclable; design parts with disassembly in mind to facilitate recycling.
• Energy Efficiency: Superior flowability allows lower melt temperatures, reducing energy consumption during molding.

Sourcing and Additional Information

• Availability: Wonderlite PC-110 is available globally through distributors listed on UL Prospector or Chi Mei’s official channels.
• Verification: Always verify material properties and compliance with Chi Mei Corporation before finalizing designs, as datasheet values may vary slightly by batch.
