PORTAFLAME® SG is produced from carefully selected, synthetic aluminium hydroxide (ATH). The standardised quality of PORTAFLAME® SG is guaranteed by means of an ISO 9001 certified quality management plan. The chemical composition of raw material and product is closely monitored and particle size kept within a narrow variation.

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 vapour. This reaction starts at about 200°C. In a ddition 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 utilised 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.
