VECTOR® 4230

VECTOR® 4230 by TSRC Corporation is a radial, styrene isoprene (SI)n block copolymer grade with a narrow molecular weight distribution. It’s radial structure provides adhesives with lower viscosity as well as higher modulus, cohesive strength and heat resistance than comparable linear SIS/SI. Formulated with the antioxidant tris(nonylphenyl) phosphite (TNPP). Produced via anionic polymerization technology using a patented coupling process that yields a polymer with primarily 4-arm radial architecture. VECTOR® 4230 is recommended for use in hot melt pressure sensitive adhesive tapes & high shear, pressure sensitive adhesive applications.
