VECTOR® 4215

• 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.
