thermoplastic elastomer SIS RUBBER Raw material for adhesive
SIS is a styrene-isoprene-styrene copolymer produced via proprietary sequential anionic polymerization,most of products are linear structures,and contains of diblock ratio is different.The finally form mainly is porous particles with outstanding thermal stability and melt process ability,mainly used in hot melt pressure sensitive adhesive for label and tape,sealant and polymer modifiers.
