Roflam 6 is a reactive halogen-free flame retardant intended for plastics. The product inhibits the solid-phase combustion process, creating on the surface of the material a charred layer that cuts off the access of oxygen from the environment and thus reduces the burning process. Due to the synergy of phosphorus-nitrogen (the product contains both elements embedded in the chemical structure), the created intumescent coatings provide extremely effective protection that allows compliance with rigorous criteria regarding flammability.

Chemical Family: Phosphorous-based Compounds, Phosphorus-Nitrogen Compounds

Properties and Applications

Non-halogen reactive flame retardant suitable for rigid polyurethane foams. It is also recommended for epoxy resins, acrylic resins as well as for phenolics.

  • effective flame retardant
  • creating intumescent coatings
  • no toxic gasses are released during the combustion process
  • permanent connection to the polymer matrix
  • effective flame retardancy of the material while maintaining its good physical and mechanical parameters
  • extending the time of retaining the functional properties of structural elements during a fire
  • construction industry – rigid polyurethane foams, construction materials based on epoxy, vinyl ester and unsaturated polyester resins
