Characteristics of FOK-670
- as a solvent and a reactive modifier -
- It is widely used as a starting material for surface-active agents of a salt of dialkylsulfosuccinic acid which has excellent permeability.
- It has a double carbon bond as the reaction and bridging point with monomers.
- It is now widely used as a modifier to improve the softness or brittleness of various resins and to adjust viscosity (viscosity reduction).
- It is authorized as a monomer for polymerization or copolymerization to polymers for food packaging by the U.S.FDA.
- We are an integrated overall manufacturer from raw materials to end products and has its own highly productive and stable supply system.
