Sylvares SA 140 Copolymer of styrene and alpha methyl styrene Arizona Chemical Tackifier >> Rosin >> Modified rosin SEALANT ADHESIVE >> Hot-melt ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) A copolymer of styrene and alpha methyl styrene particularly suited for use as an endblock-reinforcing resin in styrene-isoprene-styrene (SIS) and styrene-butadiene-styrene (SBS) block copolymers in pressure sensitive adhesives. SYLVARES SA 140 is compatible with natural rubber, rosin-based and terpene-based resins, and a variety of synthetic elastomers; particularly styrenecontaining copolymers. Light Color Styrene-Compatible Good Thermal Stability Formulation of lighter colored HMAs Improved cohesive strength Increased heat resistance Adhesives that can be expected to withstand the rigors of typical manufacturing practices. Hot melt pressure sensitive adhesives SIS- and SBS-based pressure sensitive adhesives SIS- and SBS-based bookbinding adhesives Sealants and caulking compounds Copolymer of styrene and alpha methyl styrene. Suits for use as an endblock-reinforcing resin in SIS and SBS block copolymers in pressure sensitive adhesives. Compatible with natural rubber, rosin-based and terpene-based resins, and a variety of synthetic elastomers particularly styrenecontaining copolymers.
