Properties and applications

 The advantages of Roflam B7:

  • effective flame retardant
  • acid source in intumescent coatings,
  • synergy with mineral flame retardants (including melamine, ammonium polyphosphate),
  • no release of toxic chemical compounds during combustion,
  • low emission of volatile organic compounds,
  • high compatibility with liquid raw materials,
  • can be used in formulations containing amine catalysts,
  • does not pose physical hazard or health risks.

The benefits of using Roflam B7:

  • obtaining materials meeting the flammability requirements (including FMVSS 302) and low emissions in the automotive industry,
  • obtaining materials meeting the flammability requirements in the construction industry (including DIN 4102-1),
  • obtaining the flame-retarding effect while maintaining good physical and mechanical parameters of finished materials,
  • extending the time of retaining the functional properties of structural elements during a fire.


  • furniture industry – mattresses, sofas, armchairs, cushions, upholstered furniture,
  • car industry – acoustic insulation, car seats,
  • construction industry – fire-resistant paints, construction materials,
  • C.A.S.E. – coatings, adhesives, sealants, elastomers.
