Overview
Our
Polycarbonate (PC) Diffused White Compound is an optically engineered material
designed specifically for automotive LED lighting applications. This compound
combines high light transmission with optimized diffusion, ensuring uniform
illumination, reduced glare, and premium aesthetic appeal. Tailored for
headlamps, tail lamps, and ambient lighting, it offers superior performance
under extreme thermal and mechanical conditions typical of the automotive
environment.
Key Highlights
- Optimized Light Diffusion:
Achieves uniform light output without hot spots or bright spots.
- High Luminous Efficiency:
Maintains superior light transmission while diffusing the LED source
effectively.
- Thermal & Dimensional
Stability: Engineered for continuous operation at elevated temperatures
common in automotive lighting.
- Excellent Impact Strength:
Ensures durability against vibration and mechanical stress.
- UV & Weather Resistance:
Protects against long-term yellowing, fading, and environmental
degradation.
- Color Stability: Maintains
consistent diffused white shade across batches for design uniformity.
- Processability: Suitable for
injection molding, blow molding, and extrusion with excellent melt flow
control.
Applications
- Automotive Headlamps &
Tail Lamps: Light diffusers and internal covers for uniform LED light
distribution.
- Interior & Ambient
Lighting: Diffused covers for dashboards, door panels, and cabin
illumination.
- Signal & Indicator
Lamps: Ensures bright, soft, and evenly distributed illumination.
- Logo & Display Lighting:
Provides uniform light diffusion for illuminated emblems and display
panels.
Technical Requirements Fulfilled
- Optical Performance: High diffusion efficiency
with minimal loss in transmittance.
- Thermal Resistance: Stable under temperatures
up to 130–140°C typical in LED housings.
- Mechanical Strength: High impact and flexural
strength for vibration resistance.
- Dimensional Stability: Minimal warpage or
shrinkage during and after molding.
- UV Resistance: Prolonged outdoor
durability without yellowing or surface cracking.
- Compatibility: Can be combined with flame
retardant or UV stabilizer masterbatches if required.
Sustainability & Quality
- RoHS and REACH compliant
materials ensure safety and environmental compliance.
- Recyclable polycarbonate
base supports sustainable automotive manufacturing practices.
- Consistent optical and
mechanical properties reduce rejection rates and enhance production
efficiency.
