As flame retardants, phosphates are useful for fireproofing materials, and are one of the ingredients in fire-extinguisher products. They are used in antifreeze as an anticorrosion agent, and also prevent caking, which means they are widely used in expanded polystyrene.
Purified phosphoric acid is used to purify vegetable oils and active carbon filters, and to manufacture titanium dioxide.
Fluorine derivates are also used as insecticides for the American market. Sodium fluosilicate is used worldwide in latex mattress foams, and calcium sulfate has a retarder effect much appreciated in the plaster and cement industry.
