VECTOR 4211 is a styrene-isoprene-styrene triblock copolymer and is produced via proprietary sequential anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite).
It is useful in applications requiring a combination of high modulus and high elasticity. It is also particularly suited for formulating adhesives for disposables that require high cohesive strength, low creep compliance, and low viscosity at low application temperatures.
