| About |
|---|
| Blend of linear SIS triblock and SI diblock copolymer. Contains ~25% SI diblock copolymer. Medium styrene. VECTOR 4213A and VECTOR 4213N styrenic block copolymers are blended products composed of a linear SIS triblock copolymer and an SI diblock copolymer. They are well-suited for use in hot melt adhesives for hygiene applications requiring superior cohesive strength and heat resistance along with low creep compliance. VECTOR 4213A SIS/SI is offered as a dense pellet supplied from the United States. VECTOR 4213N SIS/SI is offered as a porous pellet supplied from China.&& |
