SEBS Polymer 501 – Styrene Ethylene Butylene Styrene Block Copolymer

DESCRIPTION

Thermoplastic elastomer SEBS Polymer YH-501 is a low-molecular weight, linear Styrene Ethylene Butylene Styrene Block Copolymer. It can be applied to hot melt adhesive (pressure-sensitive adhesive), plastic modification and etc due to its good fluidity and low melt viscosity.

Compare to YH-501T, YH-501 is not desalted with deeper colour and has more impurity. It is recommended for dark materials rather than white or natural material.
