VECTOR 4461 Styrene-Butadiene-Styrene (SBS) Block Copolymer SBS(1) triblock copolymer. Contains <1% diblock copolymer. High styrene, high melt flow block copolymer. Supplied as a porous pellet, dusted with talc. VECTOR styrenic block copolymers find use under certain regulations as articles or as ingredients in articles intended for food contact or medical applications. Please contact your Dexco Polymers agent for a detailed letter of certification or further information. VECTOR 4461 linear, pure SBS block copolymer 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 has the lowest elasticity of the SBS family of products while providing high modulus, low creep resistance, excellent cohesive strength, and good melt processability. It is particularly suited for hot melt adhesives requiring high strength and low viscosity.
