VECTOR 4230
Styrene-Isoprene (SI)n Block Copolymer
  • Radial (SI)n (1) block copolymer.
  • Contains ~30% SI diblock copolymer.
  • High strength with low viscosity.
  • High modulus, high cohesive strength.
  • 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 4230 styrene-isoprene radial copolymer is produced via proprietary anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite).

It is made with a patented coupling process that yields a polymer primarily with a 4-arm radial architecture. The radial structure provides viscosity shear thinning as well as higher modulus, cohesive strength, and heat resistance versus linear SIS/SI with comparable styrene content and melt flow rate. It is ideally suited for pressure sensitive applications requiring high strength, low viscosity, and easy melt processing.
