Kraton D-1160 copolymer based on styrene and isoprene Kraton Polymers Styrene block copolymer (SBC) >> Styrene isoprene rubber, SIS SEALANT ADHESIVE >> Hot-melt ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Solvent based >> Contact adhesive KRATONTM D-1160 Polymer is a clear linear triblock copolymer based on styrene and isoprene with bound styrene of 19.2% mass. It is supplied from France as porous pellets dusted with a dusting agent. KRATON D-1160 Polymer is used in formulating adhesives, hot melt pressure sensitive adhesives in particular. used widely in pressure sensitive and contact adhesives for the production of a variety of tapes, labels, decals, plasters and hygienic disposable products. Other applications include sealants and mastics. The unique structure of KRATON block copolymers offers possibilities to formulate with resins that associate with either the elastomeric mid-block or the polystyrene domains. This powerful formulating tool, supplemented by the use of plasticisers, fillers and antioxidants, allows the formulator to modify a wide range of adhesive performance properties such as tack, cohesive strength, holding power, stiffness and temperature resistance. Much of the success of KRATON Polymers in these fields has been achieved by applying adhesives as hot melts. Many manufacturers have dispensed with solvent based systems in favour of modern hot melt mixing and high speed coating processes which offer advantages in efficiency and benefits for the environment. However, when solvent based systems are required, there are advantages of low viscosity, high solids contents and short dissolving times in a wide range of solvents. There is no need to premasticate KRATON polymers, and their pellet form assists handling. SIS grades are used for pressure sensitive applications Clear linear triblock SIS copolymer that contains an antioxydant. Can be used in formulating adhesives, hot melt pressure sensitive adhesives in particular. Permits to modify a wide range of adhesive performance properties such as tack, cohesive strength, holding power, stiffness and temperature resistance.
