DESCRIPTION

Thermoplastic elastomer SBS rubber 185 is oil-extended, radiation type, styrene-butadiene-styrene triblock copolymer. Its oil-filled rate is 31%, and styrene content is 32%. It can be injection moled directly due to its high fluidity. YH-185 and YH-815 are both radiation type oil-extended rubber. However the wear-resisting property and tensile strength of SBS polymer YH-185 have been significantly improved than YH-185.
