Vector 4111 Styrenic block copolymer Dexco Polymers Styrene block copolymer (SBC) >> Styrene isoprene rubber, SIS SEALANT ADHESIVE >> Hot-melt ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) VECTOR 4111 is a linear, pure SIS triblock copolymer with narrow molecular weight distribution. It is a low styrene, low modulus copolymer. It contains no residual diblock. It is the softest pure SIS triblock and has the highest elasticity. It has outstanding melt processibility. It is designed for use in elastomeric films and highly elastomeric compounds. Vector styrenic block copolymer - tailored product with excellent purity and consistency as well as high performance properties. This copolymer can be combined with hydrocarbon resins as an ideal choice for many adhesive applications such as pressure sensitive adhesives for tapes and labels, hot melt product assembly adhesives, construction adhesives, mastics, and sealants. Improved shear strength and heat resistance compared to formulations containing conventional process copolymers. Aging resistance and color stability under thermal stress may also be greatly improved, due to the halide-free nature of many of Dexco’s products, leading to potential savings in stabilizer costs. Linear, pure SIS triblock copolymer. Used for adhesives and sealants applications. Offers good purity and consistency, and high performance properties. Improves shear strength, heat resistance and aging resistance and color stability under thermal stress. Can be combined with hydrocarbon resins for many adhesive applications.
