- Benefits and Features
Portaflame® SG -LV and -LSA grades are ground halogen-free flame retardant (HFFR) fillers, used in a broad range of applications. 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 -LV and -LSA range possess a strong smoke-suppressing ability.. Portaflame® SG -LV and -LSA grades 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.
