A, the PS diffusion plate
　　PS diffusion plate as the name suggests is to use the PS made of , PS Chinese called polystyrene , a petroleum chemical in a relatively low-level of transparent plastic brittle , English as GPPS ,, accounted for only 1.047 ~ 1.049, the diffusion plate is light by PMMA / PC / PS diffusion layer and the like of the substrate, the refractive index of dissimilarity meet its medium (diffusing particles) occurs when multi-angle, refraction, reflection and scattering of multi-directional phenomenon, so as to achieve a light diffusion effect to provide a uniform surface light source for the display lighting components.

Two, the PS diffusion plate Features
1, PS light diffusion plate gravity is 1.05 , the mass ratio of PC, PMMA and so light, greatly reducing the cost of transportation.
2, its light transmittance of 75% or more, with respect to its PC, PMMA and other relatively inexpensive and mass adoption.

Three, the PS diffusion plate applications
1, the diffusion plate is suitable for direct type light source LED lighting, such as downlights, grille, high-grade aluminum lamp.
2, a side light diffusion plate is suitable for LED lighting, such as flat lights, advertising light boxes, professional film viewer, usually with the use of the light guide plate.
