Message
VECTOR 4215A Styrene-Isoprene-Styrene/Styrene-Isoprene (SIS/SI) Block Copolymer SIS triblock / SI diblock (SIS/SI)(1) copolymer blend. Contains ~18% SI diblock copolymer. Medium styrene copolymer. Outstanding thermal stability and melt processability. Supplied as a dense 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 4215A is a blend of linear, pure styrene-isoprene-styrene triblock and pure styrene-isoprene diblock copolymers. The individual components are 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 suited for applications where a higher modulus, higher temperature end-use, and enhanced creep resistance is desired versus VECTOR 4113A SIS/SI. It is designed for use in hot melt adhesive applications such as disposable adhesives requiring superior cohesive strength and heat resistance along with low creep compliance.
