SIS (Styrene-Isoprene Block Copolymer)

Introduction:

SIS is styrene - isoprene block copolymer in the form of white porous particle or translucent compact particle, with features of good thermo-plasticity, high elasticity, good melt fluidity, good compatibility with tackifying resin, safe and non-toxic. It can be applied to the hot-melt pressure-sensitive adhesives, solvent cements, flexible printing plates, plastics and asphalt modification, and is the ideal raw materials of adhesives used to manufacture packing bags, sanitation supplies, double-sided adhesive tapes and labels.
