ExxonMobil Santoprene® 191-85PA Thermoplastic Elastomer (discontinued **)
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Vulcanizate Elastomer (TPV)
Material Notes:	A soft, black, specialty thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. It is especially formulated to bond to PA-6 and blends thereof for applications where hard/soft combinations are required. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding or extrusion. It is polyolefin based and completely recyclable. Key Features: Designed for soft touch applications. Designed for excellent adhesion onto nylon-6 (insert or 2K [two-shot] molding) and nylon 6,6 (2K molding only). Adhesion values can vary according to type of nylon used, tool design and processing conditions. EU and China RoHS compliant Applications: Automotive-Plugs, Bumpers, Grommets, Clips, Electronics, Kitchen Tools, Power Tools and Consumer Applications Uses: Appliance Components Appliances Automotive Applications Automotive Under the Hood Bonding Cell Phones Consumer Applications Cookware Handles Eyeglass Frames Flexible Grips Kitchenware Living Hinges Seals Sporting Goods Strain Reliefs Tie-Layer White Goods & Small Appliances Availability: Africa & Middle East, Europe, North America, Asia Pacific, Latin America and South America Information provided by ExxonMobil Chemical
