Kraton D-4153 oil-extended copolymer based on styrene and butadiene Kraton Polymers Styrene block copolymer (SBC) >> Styrene butadiene styrene rubber, SBS ADHESIVE >> Solvent based >> Contact adhesive ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) SEALANT KRATONTM D-4153 Polymer is an oil-extended linear block copolymer based on styrene and butadiene, with bound styrene in the neat polymer of 35% mass. It contains 40phr paraffinic oil which is classified as not hazardous. Information on the CAS and EINECS registry numbers of the paraffinic oil used for this grade is available on request. KRATON D-4153 Polymer is supplied from Europe in two physical forms KRATON D-4153 Polymer is used in formulating compounds for footwear, technical and general purpose applications. It can also be used in formulating adhesives, sealants and coatings and as a modifier of bitumen. 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. SBS grades are preferred for contact adhesives. Oil-extended linear SBS copolymer. Contains a paraffinic oil. Can be used in formulating adhesives and sealants. Preferred for use in contact adhesives. Permits to modify a wide range of adhesive performance properties such as tack, cohesive strength, holding power, stiffness and temperature resistance.
