Tospearl™ 120FL
2 micron microfine silicone resin for use as an antiblocking agent in plastic films.
Tospearl 120FL is 2 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.
Specifications
Appearance: White spherical beads Mean particle diameter (µm): 1.8-2.3 Weight loss @ 250°C and 0.5 hours, %: <1.0 pH²: 6.0-8.0 Bulk specific gravity: 0.35 Particle specific gravity: 1.32 Refractive index: 1.42
Primary Chemistry: Methyl Silsesquioxane beads
Features & Benefits
Uniform particle size High heat resistance Low surface energy Low refractive index Non migratory
Problems Solved
Large particle size distribution of micro silicone slip additives High friction and insufficient lubricity in the manufacturing of BOPP films Tearing or adhesion of plastics films in high-speed machines due to insufficient lubricity
Applications
Antiblock masterbatch Food packaging Industrial clear films BOPP Films
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™ is a uniform spherical silicone resin that provides antiblock and slip performance capabilities for various plastic film applications.
