Kraton G-1654E copolymer based on styrene and ethylene/butylene 66070-58-4 Kraton Polymers Styrene block copolymer (SBC) >> Styrene ethylene butadiene styrene Rubber, SEBS ADHESIVE >> Solvent based >> Contact adhesive ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) SEALANT KRATONTM G-1654E Polymer is a clear linear triblock copolymer based on styrene and ethylene/butylene, S-E/B-S, with bound styrene of 31% mass. It contains antioxidants and is supplied as undusted `fluffy` crumb. 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. Kraton G polymers offer improved resistance to ageing and degradation at elevated temperatures. Consequently it is used for sealants and high performance adhesives. Clear linear triblock SEBS copolymer containing antioxidants. Offers improved resistance to ageing and degradation at elevated temperatures. Used for sealants and high performance adhesives. Permits to modify a wide range of adhesive performance properties such as tack, cohesive strength, holding power, stiffness and temperature resistance.
