Phyrolex flame retardants have a higher char yield than intumescent mixtures The Phyrolex flame retardants activate with little or no smoke emission and if the polymers and substrates are prevented from decomposition to flammable fractions then the overall smoke yield is lower The Phyrolex product range is the result of extensive research, development & design and offers excellent intumescent fire protection for a wide range of substrates The principle behind Phyrolex is to take the functional components of a conventional intumescent formulation and react these into a polymeric molecule The Phyrolex products are unique technology in fire protection and retardancy
