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.
Availability of silicone resins in micro-fine particle size for use as slip and anti-block additives
Insufficient lubricity and low heat stability of commercially available slip agents
Agglomeration of polymers during processing that results in reducing production speed
Low performance or compatibility issues of PMMA as light diffusion additives
High minimum order quantity and long lead time of micro-fine silicone resin

Momentive Tospearl™ Additives
Momentive's Tospearl™ resins allow for higher quality and less downtime at the converter and faster extrusion while manufacturing films. No need to worry about adhesion on the finished roll or the inside of the bubble.
Momentive Tospearl™ Slip Additive
The Tospearl™ series of micro-fine silicone resins decreases the contact between film layers, lowering the coefficient of friction (COF) and thus preventing them from sticking together.
