  • Processing: Suitable for injection molding with excellent flowability, allowing for complex geometries and reduced mold deposits.

Applications:

1. Outdoor Signage and Traffic Signs
   • Application Description: PC-110U is widely used for traffic signs, outdoor displays, and illuminated signage due to its UV stability, transparency, and impact resistance.
   • Example: Traffic signs, such as stop or yield signs, benefit from PC-110U’s ability to resist fading and cracking under UV exposure and extreme weather.
2.  Automotive Exterior Components
   • Application Description: PC-110U is suitable for automotive exterior parts, such as headlamp lenses, indicator light casings, and trim components, due to its clarity, heat resistance, and durability.
   • Example: Headlamp lenses made with PC-110U maintain clarity and structural integrity under thermal cycling and UV exposure, with a typical thickness of 3–5 mm.
3.  Consumer Electronics Housings
   • Application Description: PC-110U is used for transparent or translucent housings in consumer electronics, such as smartphone cases, remote control covers, and wearable device components.
   • Example: Transparent smartwatch covers made with PC-110U offer durability and clarity, with injection-molded parts maintaining precise fit with internal electronics.
4. Medical Device Components
   • Application Description: PC-110U is suitable for medical device housings and components that require sterilization, transparency, and biocompatibility.
   • Example: Transparent housings for portable diagnostic devices, with wall thicknesses of 2–3 mm, benefit from PC-110U’s clarity and sterilization compatibility.
5. High-Heel Shoe Components
   • Application Description: PC-110U is used for transparent or colored high-heel shoe components, such as heel supports or decorative elements, due to its aesthetic appeal and mechanical strength.
   • Example: Transparent high-heel supports made with PC-110U combine aesthetic appeal with mechanical reliability, typically molded at 2–4 mm thickness.

Design Guidelines

• Wall Thickness:
  • Optimize between 1.5–4 mm to balance strength, clarity, and material usage.
  • Thinner walls (1–2 mm) are suitable for electronics, while thicker walls (3–4 mm) are ideal for signage or automotive parts.
• Mold Design: Use polished mold surfaces for optical clarity and incorporate draft angles (0.5–1°) for easy demolding. Maintain melt temperatures between 280–320°C for optimal flowability.
• Assembly: Leverage PC-110U’s dimensional stability for snap-fits and tight tolerances. Avoid excessive stress concentrations in high-impact areas.
• Environmental Considerations: The non-phosgene production process reduces environmental impact, aligning with sustainability goals.
