SEBS Polymer 502 – Styrene Ethylene Butylene Styrene Block Copolymer 502

DESCRIPTION

Thermoplastic elastomer SEBS(Styrene Ethylene Butylene Styrene) Polymer YH-502 can be applied to plastic modification, making soft TPE (Shore A20-40), transparent soft toy such as frozen candle, hot melt adhesive, glass sealants, plastic modification, anti-vibration materials and etc due to its medium molecular weight, good flexible processing and favorable transparency. It can also be blended with other grades.

Compare to SEBS Polymer YH-502T, SEBS Polymer YH-502 is not desalted with deeper colour and has more impurity. SEBS polymer 502 is recommended for dark materials rather than white or natural material.
