Dow Corning Silicone-Based Additives for Polyamide Compounds - 1

Plastics & Composites Dow Corning Silicone-Based Additives for Polyamide Compounds Improved Scratch Resistance and Slip Performance in Polyamide Compounds While Dow Corning 31-441 Additive offers some enhancement to anti-scratch properties, it also excels in imparting high slip properties at low loadings. Testing has shown Dow Corning® MB50-011 Masterbatch to be the more efficient anti-scratch additive. Which is best for you depends on the application. Do you need to improve both scratch resistance and slip performance of polyamide compounds? Dow Corning® 31-441 Additive improves both, offering: • Instantaneous and stable benefits • Long-term efficiency Features & Benefits • Off-white solid silicone polymer • Improves scratch resistance • Processing aid to lower torque Figure 1: Dow Corning 31-441 Additive Slip Performance • Automotive components • Electrical and electronics • For improved coefficient of friction in the extruding or injection 0.1 process, Dow Corning 31-441 Additive is the better choice.
