2 micron micro-fine silicone resin that provide light diffusion properties for use in commercial lighting and optical applications.
Product Overview
TSR9000 Spherical Silicone Resin is a 2 micron size micro-fine silicone resin that is used as a light diffuser additive in plastic resins. The low refractive index of TSR9000 diffuses point line light and gives a matte finish. TSR9000 helps in fabrication of parts that use a light source on the back side of the part. It has good heat stability and can withstand the heat generated during plastic extrusion.
