Product Description
VECTOR 4211
Styrene-Isoprene-Styrene (SIS) Block Copolymer
  • SIS(1) triblock copolymer.
  • Contains < 1% diblock copolymer.
  • Medium styrene, high modulus 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 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.
