SEBS Polymer 561 – Styrene Ethylene Butylene Styrene Block Copolymer 561

SEBS Polymer 561 DESCRIPTION

Thermoplastic elastomer sebs rubber YH-561  is a mixture of YH-503 and YH-602 at certain proportion and is specially designed for low hardness TPE. Compared with other SEBSs(styrene ethylene butylene styrene) , YH-561 performs better in elastic recovery and tensile strength in high oil-filled contents. Compare to sebs polymer YH-561T, YH-561 is not desalted with deeper colour and has more impurity. It is recommended for dark materials rather than white or natural material.
