BEC Materials SEBS 503
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Styrene Butadiene Rubber
Material Notes:	Description: With the highest molecular weight among the linear SEBSs rubber and excellent mechanical property at high filling contents, SEBS Polymer YH-503 is mainly used to produce compound product. Compare to SEBS Polymer YH-503T, thermoplastic elastomer sebs (styrene ethylene butylenestyrene) block copolymer YH-503 is not desalted with deeper color and has more impurity. It is recommended for dark materials rather than white or natural material. Application: Plastic modification/Compounding Formula: Soft Touch Overmolding TPE (Parts by mass) SEBS polymer (YH-503): 32 Oil: 36 PP: 20 CaCO3: 12 Information provided by BEC Materials, LLC
