IP68-Rated Polycarbonate Compound with Optimized Light Diffusion for Wet Locations

Light Diffusion PC product models in the LED lighting field

Production Description:

Polycarbonate (PC) is a molecular chain containing carbonate base polymer, ac-cording to the structure of the ester base can be divided into aliphatic, aromatic,aliphatic, aromatic, and other types.Because of aliphatic and mechanical properties of aliphatic and aromatic polycarbonate is low, which limits its applicationin the field of engineering plastics.There are only aromatic polycarbonate wonthe industrialized production.Due to the particularity of polycarbonate structure, has become the fastest growing in the five engineering plastics of generalengineering plastics. PC is characterized by high transparency, high impact resistance, high hardness, high creep-resistance, excellent dimensional stability,good resistance to low-temperature and heat, flame retardance, ease to process,and excellent sound insulation.

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.
