Product Name:Styrene-isoprene-styrene block copolymer (SIS)
English Name:Styrene-isoprene-styrene block copolymer (SIS)
CAS No.:25038-32-8
Aliases:SIS elastomer, SIS rubber, Styrene-isoprene copolymer
Molecular Formula:(C8H8)x(C5H8)y
Physical Properties:White to light yellow porous granular thermoplastic elastomer with a density of 0.92–0.95 g/cm³. Solvent-free, wide bonding range, high hardness and good toughness. Soluble in cyclohexane, toluene and other organic solvents; insoluble in water.
Uses:Used in electrical tape, protective masking, diapers, feminine hygiene products, double-sided tape, labels, medical and healthcare, bookbinding, surface protective film, woodworking, wallpaper and shoemaking, featuring a solvent-free formulation and a wide bonding range. SIS elastomer exhibits good processability and storage stability in asphalt modification, with high hardness, good toughness, and excellent anti-slip and wear resistance, suitable for road pavement at various grades. Hydrogenated SIS (SEPS) can be compounded into carrier oils to produce viscosity index improvers and shear strength improvers with excellent high-temperature oxygen resistance.
Technical Specifications:
Appearance: white or light yellow porous elastomer granules.
Density: 0.92–0.95 g/cm³.
Styrene content (typical): 15%–30%.
Tensile strength (typical): ≥15 MPa.
Packaging: 20 kg/bag.
