VECTOR 4411A is a styrene-isoprene-styrene triblock copolymer produced via proprietary sequential anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is not formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite).

It is a high styrene, low viscosity product with a high modulus and excellent creep resistance. It is the least elastic of the SIS products. It is a flexible thermoplastic resin that can be blended with medium or low styrene SIS and/or SBS copolymers. It is designed for use as a compatibilizer in styrenic/olefinic blends. It has good physical properties and outstanding melt processability. It is particularly suited for use in hot melt adhesive applications for disposable articles.
