Sinopec SEPS YH-4051

Sinopec SEPS YH-4051 is a clear linear triblock copolymer based on Styrene-Ethylene-Propylene, S-E/P-S, with bound styrene of 30% mass. Compared with SEBS, Sinopec SEPS YH-4051 has advantages of fast oil absorption speed, low surface adhesion after oil absorption, high hardness and tensile strength, low permanent deformation, and good adhesion properties with a variety of polar and non-polar materials.
