RICC® series PMMA photodiffusers are polydisperse microspheres with different cross-linking densities. The average particle size is 3-6 μm and the refractive index is about 1.49. The product has spherical organic microparticles, uniform particle size distribution, excellent temperature resistance, solvent resistance, good dispersion, acid and alkali resistance, good compatibility, strong mechanical and impact strength, outstanding pressure resistance, suitable for a variety of systems. Suitable for PC, PS and other optical diffusion plate, the same can be used for optical diffusion film. For LED lighting lampholder, Lampshade, lamp tube and other products, in order to ensure high light transmittance of LED lamp beads issued by the dazzling point light source diffused into uniform, soft light source or surface light source. With excellent light diffusion effect, in the material to maintain a high light transmittance, with good haze, eliminate glare. At the same time can be used as a matting agent for paint ink; feel improver; plastic, rubber fillers and improvers; cosmetic fillers, with improved mobility, improved tactile and dispersibility; lithium battery binder, play the role of bonding barrier.
