| VECTOR® 4186A VECTOR 4186A Styrene-Isoprene (SI)n Block Copolymer Radial (SI)n(1) block copolymer. High molecular weight copolymer. Contains ~73% SI diblock copolymer. 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 4186A styrene-isoprene radial copolymer is produced via proprietary anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is not 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. It is particularly suited for low-viscosity hot melt pressure sensitive adhesive systems having excellent adhesion to low energy surfaces, low migration characteristics, and enhanced die-cutting characteristics within label stock applications.&&VECTOR® 4186A Radial (SI)n block copolymer. Contains ~73% SI diblock copolymer. Low styrene. VECTOR 4186A styrenic block copolymer is a radial block copolymer with a narrow molecular weight distribution. It is well-suited for use in low viscosity hot melt pressure sensitive adhesive applications requiring excellent adhesion to low energy surfaces, low migration characteristics, and enhanced die-cutting characteristics. VECTOR 4186A (SI) n is offered as a dense pellet supplied from the United States.&& |
