Tospearl Micro-Fine Silicone Resins

Tospearl™ micro-fine silicone resins are spherical polymer powders designed with a very narrow particle distribution and are ideal for film and optical applications. In film applications, they act as a slip-additive or anti-blocking agent. They provide high-heat stability and superb lubricity, which prevents agglomeration and allows greater production flexibility, and can also be run at higher processing speeds to increase efficiency and throughput, while minimizing downtime.

In light diffusion applications its particle size uniformity puts its quality above competitive material and the chemical composition makes for an attractive and cost effective offset to PMMA type additives.
