Product Benefits
  • Based on an organic metal phosphinate
  • Not hygroscopic, insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene Good hydrolysis resistance
  • Can easily be dispersed in solvents like acetone or MEK
  • Halogen-free flame retardant with a high phosphorus content which is suitable for use in both thermoplastic and thermoset applications to meet the most stringent fire retardancy standards
  • Suited for thermoplastic elastomers for cable applications
  • Particularly suitable for very thin adhesive applications like flexible printed circuit boards due to its specifically designed particle size distribution; can be readily dispersed in epoxy resin systems when a high shear mixer is used
  • Low smoke toxicity
  • Non-halogenated flame retardant with favorable environmental and health profile
