Vector 8508 Styrenic block copolymer Dexco Polymers Styrene block copolymer (SBC) >> Styrene isoprene rubber, SIS ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Hot-melt SEALANT VECTOR 8508 is a linear, pure SBS triblock copolymer. It is a medium styrene, medium viscosity product. It contains no residual diblock. It has excellent thermoplastic elastomer properties, melt processibility, and physical strength. It has superior melt processibility when compared to Vector 2518. It is designed for use as an impact/ toughness modifier in styrenics and in elastomeric films. 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, SBS triblock copolymer. Used for adhesives and sealants applications. Provides very good thermoplastic elastomer properties, melt processibility, and physical strength. Offers good purity and consistency, and high performance properties. Can be combined with hydrocarbon resins for many adhesive applications (PSA).
