SIS /STYRENE ISOPRENE STYRENE Chiyaun brand high quality

Product Overview

Description

SIS  

SIS is a styrene-isoprene-styrene mixture of triblock copolymer and diblock copolymer produced via proprietary sequential anionic polymerization, linear structure, contains of diblock ratio about 50%.    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.It is with good original adhesion and good color bleeding resistance,mainly used in hot  melt pressure sensitive adhesive for label and tape.
