- UV Stability: Enhanced weathering resistance, ensuring durability in outdoor environments exposed to sunlight.
- Dimensional Stability: Low thermal expansion and high stiffness, ensuring consistent performance in precision applications.
- Flammability: Complies with UL 94 V-2 flame rating (non-halogenated, no chlorinated solvents).
- Processing: Suitable for injection molding with excellent flowability, allowing for complex geometries and reduced mold deposits.
Applications:
- 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.
- 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.
- 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.
- 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.
- 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.
