Silica Inorganic Light Diffuser is anti-aging inorganic optical additive designed for PP diffusion sheet. High-purity silica particles can form stable light scattering structure inside PP resin matrix. It effectively refracts and diffuses light, removes glare and uneven light spots, and achieves soft and uniform light transmission for PP diffusion sheets.
Different from organic diffusers, silica owns excellent anti-ultraviolet and anti-aging capability. It resists long-term light irradiation, e

Product Detail

Product Introduction

Silica Inorganic Light Diffuser is a professional anti-aging inorganic optical additive developed for PP light diffusion sheets. Made of high-purity silica particles with stable inorganic structure, it can form uniform light scattering networks within PP resin matrix. The particles continuously refract and diffuse incident light, effectively disperse concentrated point light sources, eliminate harsh glare and irregular light spots, and endow PP diffusion sheets with soft, comfortable and homogeneous light transmission effect.

Compared with traditional organic light diffusing microspheres, silica features prominent anti-UV and anti-aging advantages. It will not degrade or turn yellow under long-term illumination, maintaining consistent haze and light uniformity for a long time. The product has good compatibility with polypropylene resin, perfectly matching continuous extrusion production of PP optical diffusion sheets, and meets the manufacturing requirements of indoor and outdoor lighting components that demand long service life.

Core Advantages

Excellent anti-aging and anti-yellowing property. As stable inorganic filler, silica withstands ultraviolet radiation, effectively delays material aging, avoids yellow discoloration of diffusion sheets during long-term use.

Stable light scattering performance. Uniform particle morphology provides reliable light homogenization effect. Reasonable dosage balances light transmittance and haze to satisfy different lighting design standards.

Good processing performance. The powder owns favorable dispersibility in PP melt. With conventional mixing equipment, it can be evenly blended with PP pellets, reducing risks of agglomeration, fish eyes and surface streaks on finished sheets.

Outstanding chemical inertness. It does not chemically react with PP base material, maintains stable performance under normal extrusion temperature, and will not pollute the resin system.

Application Scope

Silica Inorganic Light Diffuser is mainly applicable to polypropylene resin system. It is widely used for extruded PP light diffusion sheets, PP lighting panels, LED lamp diffuser accessories and outdoor lighting optical components. It is suitable for products requiring long-term weather resistance and stable light effect.

This product is an inorganic optical additive. For ultra-high light scattering requirements, customers can try to compound it with organic light diffusers to achieve customized optical indicators.

Usage Guidance

Adjust the specific addition proportion according to target light transmittance, haze and light uniformity of PP diffusion sheets. Fully mix silica light diffuser powder with PP raw pellets before feeding. Adopt standard processing parameters of PP extrusion, avoid excessive temperature and prolonged material residence inside the barrel. Sufficient mixing ensures stable and consistent optical performance during continuous mass production.

Packaging and Storage

The product adopts sealed moisture-proof packaging to prevent powder moisture absorption and agglomeration. Store in dry, cool and ventilated warehouse, keep away from direct sunlight, high temperature and humid environment. Tightly seal the package after each use. Under proper storage conditions, the powder can retain stable physical and optical properties within shelf life.
