Product Overview

Longcliffe manufactures an extensive range of specialty products, including Refox Calcium Oxide, Hydralon Calcium Hydroxide and Fluoromag Magnesium Oxide.

Refox Calcium Oxide Properties and Benefits

Refox is a high purity calcium oxide (CaO) processed at our company’s manufacturing operations in Derbyshire. The material has been calcined, milled and classified to produce a product of exceptional purity with a consistent reactivity. Products are available in powder and dispersed forms to meet specific processing requirements. Food and industrial grades are also available. For further information please consult the relevant technical data sheet.

Hydralon Calcium Hydroxide Properties and Benefits

Hydralon is a high quality calcium hydroxide (Ca(OH)2) or hydrated lime produced from high purity Carboniferous limestone that has been subjected to closely controlled calcination followed by stoichiometric hydration. Industrial, feed and food grades are available including products specifically formulated for use in fluoroelastomer systems. For further information please consult the relevant technical data sheet.

Fluoromag Magnesium Oxide Properties and Benefits

Fluoromag is a high activity magnesium oxide (MgO) produced from sea water magnesia that has been further processed in order to produce a range of products that offer consistent activity in halogenated polymer cure systems. Fluoromag is primarily used as an acid acceptor in fluoroelastomers and polychloroprene compounds. For further information please consult the relevant technical data sheet.

Speciality Products Grades

Longcliffe calcined products are available in a range of grades to suit different applications. Please contact us for further information.

Our operations are fully accredited to ISO 9001 and ISO 14001. Datasheets and SDS on specific grades are available on request. Please contact us for further information.

Packaging

Refox Calcium Oxide, Hydralon Calcium Hydroxide and Fluoromag Magnesium Oxide are available in IBCs and sacks - palletised and shrunk wrapped if required.
