Kraton G-1730M Copolymer based on styrene and ethylene/propylene 68648-89-5 Kraton Polymers Styrene block copolymer (SBC) >> Styrene ethylene propylene styrene, SEPS SEALANT ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) ADHESIVE >> Solvent based >> Contact adhesive KRATONTM G-1730M Polymer is a linear block copolymer based on styrene and ethylene/propylene, S-E/P, with bound styrene of 20% mass. It is supplied from Europe as dense pellet. KRATON G-1730M Polymer is used as a base material for compound formulations and as a modifier of thermoplastics. The inherent stability of the mid block suggests the use of G-1730M in applications that must withstand weathering and high processing temperatures. 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 block SEP copolymer. Offers improved resistance to ageing and degradation at elevated temperatures. Used for sealants, high performance adhesives and in applications that must withstand weathering and high processing temperatures. Permits to modify a wide range of adhesive performance properties such as tack, cohesive strength, holding power, stiffness and temperature resistance.
