The light diffusing agent is a micron-sized silicone microsphere powder, which mainly imparts different refractive light diffusion effects to PC, PMMA, PS, PP and other plastics. The main product is used for LED lampshade, light diffusing plate, light transmittance. It has good balance with diffusivity, good dispersion and stability, and can choose a variety of particle sizes. Excellent lubricity, resulting in a soft, smooth, silky feel, added to transparent resins such as basic resins and polycarbonate resins, or used on the surface of transparent film such as PET film, which allows the transmitted light to diverge as a reduction The light-diffusing material that reflects light has a high penetrability, reduces waste of light transmittance, and improves sharpness, compared with the inorganic series of titanium oxide barium sulfate or the like which is usually used.

Excellent light diffusivity

Through the combination with polycarbonate, polystyrene, acrylic resin, etc., it has very good light diffusivity and high total light transmittance in a small amount, which is very suitable for liquid crystal display, light. Application in the field of diffuser plates and polypropylene plastic stools.
