SIS is a thermoplastic block copolymer based on styrene-isoprene-styrene,mainly used for HMPSA,modification of plastic&bitume
Description:SIS 1201 is a thermoplastic block copolymer based on styrene-isoprene-styrene. The middle block-isoprene, whose structure of lateral methyl and unique micro split-phase structure, determines its superiority while used as adhesives.Advantage:With excellent elasticity, low modulus and good corrugated tightness, high temperature resistance, the pressure sensitive adhesive(PSA) and hot melt adhesive which are made from SIS have properties of good flexibility, adhesive strength,cohesion force, also left no trace with stripping it.Application:Therefore, it can be used in the fields like medical treatment,hygiene, electric insulation, packaging, maskant, marking, etc.
