- Benefits and Features
Our range of PORTAFLAME SG micronized halogen-free flame retardant (HFFR) fillers is used in a broad range of applications such as SMC & BMC, wire & cable compounds, resin potting compounds, coatings, sealants and adhesives. Their flame-retarding action is based mainly upon the endothermic decomposition of metal hydroxide (heat-sink effect) and simultaneous release of water vapor. This reaction starts at about 200°C. In addition to flame retardancy, fillers in the PORTAFLAME SG range posses a strong smoke-suppressing ability.. Development of Halogen Free Flame Retardant (HFFR) products is one of the ongoing high priority areas of the industry. The application of mineral based flame-retardant fillers is one of the options to replace traditional halogenated FR-products that are in the process of new regulatory measures from the authorities. Hot topics are the persistency of halogenated flame-retardants in the environment and the formation of polyhalogenated toxic compounds during thermal degradation of certain halogenated flame-retardants. PORTAFLAME SG products are utilized as effective and economical flame retardants and/or smoke suppressants. They are not classified as a dangerous substance (DSD and CLP) and do not contain Substances of Very High Concern (SVHC), including their decomposition products from fire.
