| VECTOR® 4113A VECTOR 4113A Styrene-Isoprene-Styrene/Styrene-Isoprene (SIS/SI) Block Copolymer SIS triblock / SI diblock (SIS/SI)(1) copolymer blend. Contains ~18% SI diblock copolymer. Low styrene, low viscosity, low 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 4113A is a blend of linear, pure styrene-isoprene-styrene triblock and pure styrene-isoprene diblock copolymers. The individual components are produced via proprietary sequential anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It is not formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite). It is a soft SIS/SI block copolymer blend. It is softer than VECTOR 4111A pure triblock copolymer due to the presence of ~18% SI diblock. It is well suited for use in formulating adhesives and in photopolymer plate applications.&&VECTOR® 4113A Blend of linear SIS triblock and SI diblock copolymer. Contains ~18% SI diblock copolymer. Low styrene, low modulus. VECTOR 4113A and VECTOR 4113N styrenic block copolymers are blended products composed of a linear SIS triblock copolymer and an SI diblock copolymer. They are softer than VECTOR 4111A SIS/SI due to lower styrene content and presence of diblock copolymer, making them well-suited for use in hot melt pressure sensitive adhesives, elastomer compounds and photopolymer plate applications. VECTOR 4113A SIS/SI is offered as a dense pellet supplied from the United States. VECTOR 4113N SIS/SI is offered as a porous pellet supplied from China.&& |
