Overview
Momentive Tospearl™ 130FL is a 3-micron size micro-fine spherical silicone resin used as an additive in biaxially oriented polypropylene (BOPP) films as a slip and antiblocking agent. Momentive Tospearl™130FL as a slip agent improves the coefficient of friction (COF) to facilitate easier processing and faster line speeds and to prevent the film from tearing. Momentive Tospearl™, when used as an antiblocking agent, prevents adhesion during film production both on a finished roll or on the inside of the bubble. Tospearl™ 130FL spherical silicone resin additives provide excellent water repellency, lubricity, and thermal resistance.
