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 butylene styrene) block copolymer YH-503 is not desalted with deeper colour and has more impurity. It is recommended for dark materials rather than white or natural material.
