Water Resistant Optical Diffusion PC Pellets Humidity Prone Lighting Systems Use

Water-Resistant Optical Diffusion Polycarbonate Material for Humidity-Prone Lighting Systems

Light Diffusion PC product models in the LED lighting field

Production Description:

Chemically stabilized PC variants utilize UV-absorber masterbatches and anti-static coatings to achieve weatherability Class 1 (ISO 4892) and surface resistivity 10⁶-10⁹ Ω/sq. These food-contact compliant grades (FDA 21 CFR 177.1580) prevent microbial adhesion in medical tubing and dishwasher-safe food containers.

Key Advantages Over Standard PC:

• Tailored Performance: Balances transparency, strength, and processability for niche uses.

• Cost Reduction: Blends like PC/ABS lower material costs while maintaining core properties.

• Durability: Enhanced UV, chemical, and thermal stability for harsh environments.

• Regulatory Compliance: Meets flame safety (UL94), food contact (FDA), and medical standards.
