Application: The new thermoplastic elastomer rubber SIS is a styrene-isoprene-styrene block copolymer. With its thermoplastic property, high elasticity ,low melting index and viscosity and good compatibility with viscosity-enhanced resin, SIS is popular with the fields of adhesives, coatings and plastic modification, mainly used for hot-melt pressure-sensitive adhestive to produce packing bags, women napkin, paper diaper, two-side belts and oil resistant labels.
Packing: 25kgs / 20kgs per bag, palletized on the pallet, shrinked
Precaution: Should be stored under cover in a cool, dry place. The shelf life is one year.
