Uniform dispersion of light diffusing agent, unstable optical performance in the preparation of the light diffusing PC material, use a multi-scale complex and masterbatch technology to improve dispersion and compatibility of light diffusion agent in the PC, improved optical performance of light diffusion composite material.

LED is a point light source. In practical applications, it is usually necessary to transform it into a line light source or a surface light source to make the light bright and soft. To achieve this transformation, it is inseparable from an indispensable light diffusion material. Light diffusion materials are generally composed of light diffusion agent and polymers, which are supplied to the market in the form of light diffusion plastics, light diffusion encapsulant, light diffusion coating and ink. How’s the dosage ratio and particle size of light diffusion agent affect the effect of light diffuser? let’s discuss together

when you buy light diffusion agent, many factors should be consider, especially the brightness, purity, purity of the three factors must be considered, otherwise it is likely to buy inferior materials, resulting in product problems.

In terms of the particle size of the light diffusion agent, it is 1-3μm, 2-5μm, 2-8μm, 5-15μm and so on. different kinds of silicone resin powder have different astigmatism effects and transmittance.

The types of light diffusion agent can be divided into three categories: organic particles, inorganic particles and composite materials. Scatterer particles need to meet the following three points:

Diffusion silicone resin powder WD-102 is the best-selling optical diffuser in Wanda Chemical. Its quality can be compared with that of Shinesu KMP-590, but the price is quite beautiful.
