Technical Data Sheet

SIS-2170

Styrene-Isoprene-Styrene block copolymer

SIS-2170 is a styrene-isoprene-styrene block copolymer produced via proprietary sequential anionic polymerization, linear structure. Form is porous particle with outstanding thermal stability and melt process ability, is easier to be processed and mixed than SBS,with small solution viscosity.The base material is with outstanding adhere ability,with a good balance property between adhesion and plastic move migration. It is mainly used in  hygienic products.
