DESCRIPTION

Thermoplastic elastomer (TPE polymer) sebs rubber YH-604 is radiation type in structure with molecular weight around 1.5 times as much as that of SEBS polymer 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, YH-604 is not desalted with deeper colour and has more impurity. It is recommended for dark materials rather than white or natural material.
