VECTOR® 8508 VECTOR 8508 Styrene-Butadiene-Styrene (SBS) Block Copolymer SBS(1) triblock copolymer. Contains <1% diblock copolymer. Medium styrene, low modulus copolymer. Outstanding thermal stability and excellent melt processability. Supplied as a porous 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 8508 styrene-butadiene-styrene block copolymer 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 has excellent thermoplastic elastomer properties, melt processability, and physical strength. It has superior melt processability when compared to VECTOR 2518 SBS. It is designed for use as an impact/toughness modifier in styrenics and in formulating adhesives.&&VECTOR® 8508 Linear SBS triblock copolymer. Contains <1% diblock copolymer. Medium styrene, medium modulus. VECTOR 8508 styrenic block copolymer is a linear triblock copolymer with a narrow molecular weight distribution. It has excellent thermoplastic elastomer properties and physical strength, and superior melt processability when compared to VECTOR 2518 SBS. It is formulated with the antioxidant tris(nonylphenyl) phosphite (TNPP). VECTOR 8508 SBS is offered as a porous pellet supplied from the United States.&& |
