The additives for Polyurethane
The polyurethane foam industry is facing new challenges regarding flame retardants, required to provide reduced toxicity and improved sustainability.
With the aim of combining requests for fire safety, impact on health, high performance and easy handling, REPI has developed a range of self-extinguishing Flame Retardants, on the market under the antiFIAMMA brand name.
antiFIAMMA Flame Retardants range comprises liquid blends of pure melamine dispersions along with different synergistic formulations of primary flame retardants that can be applied to FLEXIBLE and INTEGRAL FOAM as well as to RIGID PU FOAMS.
Thanks to their composition and production process, those additives represent a new concept of halogen free flame retardants able to offer perfect distribution into liquid and to enhance instrinsic fire resistance in the end-product by increasing the contact surface of the active principles with the foam.
antiFIAMMA represent a step towards safer workplaces, where classified powder handling is a real risk and source of dirt.
