Tospearl™ 3120
Momentive Tospearl™ 3120 is a spherical microfine silicone resin that is used for plastic film applications as an anti-blocking agent and improves extrusion processes for various thermoplastic materials. Tospearl™ 3120 are 12 microns in particle size which allows for a controlled consistency and distributions for polyolefin film resin.
Tospearl™ 3120 silicone resins are spherical methyl silsesquioxane beads with narrow particle size distributions and mean particle diameters. Tospearl™ 3120 is a 12-micron particle size micro-fine silicone resin that is used as an additive in biaxially oriented polypropylene (BOPP) films as a slip and anti-blocking agent. As a slip agent, it improves the Coefficient of Friction (COF) to facilitate easier processing, faster line speeds, and a low refractive index, preventing the film from tearing. Tospearl™ 3120 allows for decreased friction between film layers, preventing sticking and tackiness issues. Tospearl™ 3120 performance benefits such as high-heat tolerance, organic solvent resistance, and dispersion applications allow for a superior appearance for the product.
Momentive Tospearl™ 3120 when used as an anti-blocking additive prevents adhesion during film production both on a finished roll or on the inside of the bubble. In paint & ink applications, Tospearl™ 3120 is used to improve moisture resistance, control viscosity, and clarification of color, tone, and gloss control. As a toner additive, Tospearl™ 3120 silicone resin provides control of fluidity and prevention of static electricity.
