Siloxane additives for molding polypropylene and thermoplastic olefins CASE HISTORY Supplier Silicone plastic additives have been effectively employed for many years Dow Corning Corporation to improve lubricity and flow of thermoplastics. However, incorporating liquid silicone additives into thermoplastic melts without specialized Location equipment poses many processing difficulties. It has also been Midland, MI challenging to produce quality masterbatches with greater than 20% Application silicone content, due to processing difficulties and silicone bleeding Thermoplastics molding and problems. extrusion Dow Corning has designed its new series of additives as dry, solid pellets Problem that can be blended at the press during molding or extrusion. Based on Manufacturers of automotive ultra high molecular weight siloxane (15-20 million cs), these materials interior trim, appliances, luggage form a uniform dispersion within the polymer melt, controlling the mobility and other items are using of the siloxane and virtually eliminating problems experienced with liquid increasing amounts of additives. polypropylene (PP) and other thermoplastic olefins (TPOs) in Testing has shown that when added to PP or TPOs at levels between their products, but mar and scratch
