sis is a styrene-isoprene-styrene copolymer produced via proprietary sequential anionic polymerization,most of products are linear structures,and contains of diblock ratio is different.the finally form mainly is porous particles with outstanding thermal stability and melt process ability,mainly used in hot melt pressure sensitive adhesive for label and tape,sealant and polymer modifiers.
advantages:
1)prompt shipment,most grades are in stock,we can arrange shipment immediately.
2)can be customized as customer’s request .now our anuual productivity is 30000mt/year.
3)testing samples offered
4)our main customer:h.b.fuller,bostik etc.
styrene isoprene styrene thermoplastic block copolymer (sis) is a thermoplastic elastomer sbs (commonly known as "the third generation of rubber") sisters products, is a new generation of thermoplastic elastomer
