Si+® series help diffusion films & diffusion plates to enhance their optical characteristics. For example, Si+® series raise the haze without losing light transmittance after being applied to a light diffuser film and a plate, used in a variety of lighting conditions. The film, applied Si+® series to, can be used in both top and bottom side of a light diffuser film and a plate or one side of them to modify haze configuration. Transparent optical resins are compounded of or coated with Si+® series for light to disperse effectively. Si+ series consist of two types of products:hydrophilic and hydrophobic. Hydrophobic type products have superb dispersibility in a resin.
