Message
Blend of SIS triblock and SI diblock copolymer Medium styrene copolymer Outstanding thermal stability Outstanding melt processability Complies with U.S. FDA 21 CFR 177.1810; Consult the regulations for complete details VECTOR 4215 is a blend of SIS triblock and SI diblock copolymer with a styrene content of 30%. Its higher styrene content leads to higher modulus, higher temperature end-use, and enhanced creep resistance. It is designed for use in hot melt adhesive applications such as disposable adhesives requiring superior cohesive strength and heat resistance along with low creep compliance.
