SIS 1120 is a styrene-isoprene-styrene triblock copolymer produced via proprietary sequential anionic polymerization with a linear structure and a diblock ratio of <1%. It is in the form of a porous particle with outstanding thermal stability and melt process ability, is easier to process and mix than SBS, and has a small solution viscosity. It is mainly used in hot-melt pressure-sensitive adhesives for labels and tape.
