Product Description
VECTOR 4213A
Styrene-Isoprene-Styrene/Styrene-Isoprene (SIS/SI) Block Copolymer
  • SIS triblock / SI diblock (SIS/SI)(1) copolymer blend.
  • Contains ~25% 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 4213A 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.
