Teknor Apex Sarlink® 3140 Thermoplastic Elastomer
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Olefinic Elastomer (TPO)
Material Notes:	A low hardness, multi-purpose thermoplastic elastomer featuring excellent compression set and high temperature performance. Sarlink® 3140 can be processed by injection molding or extrusion for applications such as grips, seals, gaskets, profiles and other articles. Processing and Handling Sarlink® 3140 is a polypropylene based elastomer, which can be processed on conventional thermoplastic equipment for injection molding and extrusion. This product has a wide processing window in most applications. Melt temperatures from 360°F to 430°F can be used. Do not exceed 450°F. Drying is recommended for extrusion and blow molding and any time the material is used from an unsealed package. Extrusion screen pack is 20 to 60 mesh. PURGING This product has excellent melt stability. Empty the barrel for idle periods of thirty (30) minutes or longer. Purge thoroughly before and after use of this product with polyethylene or polypropylene. RECYCLING/REGRIND This product can be reprocessed. Physical properties are generally not degraded. Dry regrind prior to reprocessing. COLORING The use of polyolefin based color concentrates is recommended. Apply back pressure in injection molding to disperse color. BONDING/ASSEMBLY Thermal bonding techniques can be used to form high strength bonds. Adhesive bonding can be achieved with specialized adhesives. Bond strength is limited due to the polypropylene base of this material. STORAGE and HANDLING This product is available in 55 lb. foil lined bags (up to 2,200 lbs. per pallet) or 1,100 lb. polyethylene lined gaylords. It has a storage life at normal temperatures of several years. Sarlink® was sold from DSM to Teknor Apex
