- Chemical Name:Magnesium Hydroxide, Huntite
- Functions:Flame Retardant
Securoc® B9 is produced from carefully selected, naturally occurring magnesium hydroxide. The standard quality of Securoc® B is guaranteed by means of an ISO 9001-certified quality management plan. The chemical composition of the raw material and the finished product is closely monitored, and particle size is kept within a narrow variation. Securoc® B products are developed as functional halogen-free flame retardant (HFFR) fillers for plastics and rubbers. Their flame retardant activity is primarily due to the endothermic decomposition of metal hydroxide (the heat sink effect) and the simultaneous release of water vapor. This reaction starts at about 300°C. Besides being flame retardant, they also possess a strong smoke-suppressing ability. These flame retardants are used in applications where processing temperatures exceed 200ºC, making ATH unsuitable. Its main uses are in wire and cable compounds, polyolefin roofing membranes, and electrical appliances based on thermoset compounds.
