Light Diffusion Agent

A colorless optical diffusion additive for transparent lighting plastics. Its fine, regular particles redirect light through the resin to reduce visible LED points and produce a more even luminous surface while retaining useful light transmission.

Light Diffusion Agent: white diffusion powder beside illuminated spherical, tubular and shaped plastic diffusers
Product Overview

Fine optical diffusion additive that softens visible light points while balancing haze, light uniformity and transmission.

Applicable Materials

  • PP
  • PVC
  • ABS
  • PC
  • PA
  • PET
  • PETG
  • PMMA
  • GPPS
  • AS

Typical Applications

  • LED covers, lampshades, diffuser sheets and optical plastic parts
  • PP, PVC, ABS, PC, PA, PET, PETG, PMMA, GPPS and AS systems
  • Lighting products needing visual uniformity and high transmission

Key Benefits

  • Helps hide LED points and improve light uniformity
  • Balances diffuser haze with useful light transmission in transparent parts
  • Designed for high-temperature processing trials with attention to color and yellowing

Selection Notes

  • Start around 0.5-0.8% and tune by part thickness, haze target and light transmission target.
  • Suitable for compounding, injection molding, extrusion, blow molding, film or sheet trials depending on the resin system.
  • Share base resin, target performance, part thickness and process route before final grade selection.
  • Use TDS/SDS and small-batch testing to confirm dosage, appearance and final performance before mass production.
Performance and testing notice

Confirm performance in the actual formulation and process

Actual results may vary with resin grade, material condition, formulation, dosage, part thickness, material and mold temperature, equipment, processing parameters, humidity, storage and test environment. Published values and application descriptions are selection references, not unconditional guarantees. Review the current TDS / SDS and complete application-specific testing before production approval.
