Roflam B7L is a halogen-free flame retardant. It is a product completely safe for the environment and human health. Among other products belonging to the group of triaryl phosphate esters, it is distinguished by non-hazardous class according to the GHS system. In addition, due to the fact that it is a halogen-free solution, it does not cause the release of toxic gases (including hydrogen chloride, hydrogen bromide) during the combustion process.
There are several mechanisms that limit the flammability of the material. Roflam B7L inhibits the solid-phase burning process, creating on the surface of the material a charred layer that cuts off the access of oxygen and heat from the environment. In turn, halogen flame retardants most often inhibit reactions in the gas phase, which are responsible for flame propagation and heat generation. Both of these mechanisms are considered very effective.
Roflam B7L is characterized by low dynamic viscosity and low acid number, thanks to which it is successfully used in polyurethane materials. It is dedicated primarily to the production of flexible and semi-rigid polyurethane foams used in the furniture industry (mattresses, sofas, armchairs) and car (acoustic insulation, car seats), where the priority is the lack of toxic gases during the combustion process and low emission of volatile organic compounds. In addition, due to the synergy of Roflam B7L with other flame retardants, the use of the product enables compliance with stringent flammability requirements.
