Material Notes:
A highly engineered thermoplastic elastomer for use in demanding applications. Sarlink® 4339D is a flame retardant, high hardness grade processing exceptional chemical resistance, compression set and high temperature performance. This product can be processed by injection molding or extrusion. Applications include wire and cable insulation, electrical connectors, seals gaskets and boots. This product is designed as an alternate to thermoset elastomers like EPDM and chlorosulfonated polyethylene.Processing and Handling (See more in property table)Sarlink® 4339D is a polypropylene based elastomer which can be processed on conventional thermoplastic equipment for injection molding, extrusion and blow molding. This product has a wide processing window in most applications. Melt temperatures from 360°F to 420°F can be used. Do not exceed 430°F. Drying is recommended for extrusion and injection molding and any time the material is used from an unsealed package. Extrusion screen pack is 20 to 60 mesh.PURGINGThis 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/REGRINDThis product can be reprocessed. Physical properties are generally not degraded. Dry regrind prior to reprocessing. COLORINGThe use of polyolefin based color concentrates is recommended. Apply back pressure in injection molding to disperse color.BONDING/ASSEMBLYThermal 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 HANDLINGThis 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. Please refer to the Material Safety Data Sheet for this grade prior to first time handling.Sarlink® was sold from DSM to Teknor Apex
