SECUROC® B is produced from carefully selected, naturally occurring magnesium hydroxide. The standardised quality of SECUROC® B 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.

SECUROC® B products are developed as functional halogen-free flame retardant (HFFR) fillers for plastics and rubbers. 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 300°C. Besides flame retardancy, they also posses a strong smoke suppressing ability.These flame retardants are used in applications where processing temperatures exceed 200 °C, making ATH unsuitable. The main uses are in wire & cable compounds, polyolefin roofing membranes and electrical appliances based on thermoset compounds.

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 the 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. SECUROC® B 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.

Surface treated SECUROC® B 9 products are available on request. These are coded B 9 F11.0 for fatty acid and B 9 S11.0 for silane coated grades, respectively.
