3 micron microfine silicone resin for use as an antiblocking agent in plastic films.
Tospearl 130FL is 3 micron size micro-fine silicone resin that is used as an additive in biaxially oriented polypropylene (BOPP) films as a slip and antiblocking agent. As a slip agent it improves the Coefficient of Friction (COF) to facilitate easier processing, faster line speeds and prevents the film from tearing.
Tospearl when used as a antiblocking agent prevents adhesion during film production both on a finished roll or on the inside of the bubble.

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.
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.
TSR9000 from Momentive is an excellent solution for light diffusion and enhanced optical properties in polymers and resins formulations.
