| 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.&& |
