Characteristics of FOK-670

- as a solvent and a reactive modifier -

  1. It is widely used as a starting material for surface-active agents of a salt of dialkylsulfosuccinic acid which has excellent permeability.
  2. It has a double carbon bond as the reaction and bridging point with monomers.
  3. It is now widely used as a modifier to improve the softness or brittleness of various resins and to adjust viscosity (viscosity reduction).
  4. It is authorized as a monomer for polymerization or copolymerization to polymers for food packaging by the U.S.FDA.
  5. KKC is an integrated overall manufacturer from raw materials to end products and has its own highly productive and stable supply system.
