SEBS Polymer 604 - Styrene Ethylene Butylene Styrene Block Copolymer 604

SEBS Polymer  604 DESCRIPTION
Thermoplastic elastomer(TPE polymer) SEBS Polymer 604 is radiation type in structure with molecular weight around 1.5 times as much as that of YH-503T. With ultra high molecular weight, it has more physical crosslinking points so that SEBS won't be compressed in high or low temperature. Compared with other grades, it performs better in resistance to compression, mechanical property, melt flowability, and flexibility and hardness between 50~90℃. Compare to YH-604T, SEBS Polymer YH-604 is not desalted with deeper colour and has more impurity. It is recommended for dark materials rather than white or natural material.

SBS rubber 185 - Styrene Butadiene Styrene block copolymer materials SBS rubber 185 DESCRIPTION Thermoplastic elastomer SBS(Styrene Butadiene Styrene) 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.

SEBS Polymer  DESCRIPTION SEBS Polymer YH-602 is radiation type in structure with good processing flow properties, clear surface, and excellent performance in elastic recovery therefore can be made into various TPE (thermoplastic elastomer). Compare to sebs polymer YH-602T, YH-602 is not desalted with deeper colour and has more impurity. It is recommended for dark materials rather than white or natural material.
