| VECTOR® 4114A VECTOR 4114A Styrene-Isoprene-Styrene/Styrene-Isoprene (SIS/SI) Block Copolymer SIS triblock / SI diblock (SIS/SI)(1) copolymer blend. Contains ~42% SI diblock copolymer. Low styrene, very low viscosity and 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 4114A 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 the softest SIS/SI block copolymer blend due to the presence of ~42% SI diblock. It is designed for use in the modification of the modulus properties of olefinic resins and in formulating adhesives&&VECTOR® 4114A Blend of linear SIS triblock and SI diblock copolymer. Contains ~42% SI diblock copolymer. Low styrene, very low modulus. VECTOR 4114A and VECTOR 4114N styrenic block copolymers are blended products composed of a linear SIS triblock copolymer and an SI diblock copolymer. They are softer than VECTOR 4113A SIS/SI due to higher diblock content, making them well-suited for use in hot melt pressure sensitive adhesives, elastomer compounds and photopolymer plate applications. VECTOR 4114A SIS/SI is offered as a dense pellet supplied from the United States. VECTOR 4114N SIS/SI is offered as a porous pellet supplied from China.&& |
