\n Calsec <\/h1>\n \n
\n

Calsec\u00ae is a tailored formulation of specialty chemicals used, among other things, in rubber compounds. The product is available in two variants: Calsec\u00ae FE (calcium hydroxide) and Calsec\u00ae UF (calcium oxide).<\/p>\n\n

In rubber compounds, Calsec\u00ae is used primarily as a moisture absorber (Calsec\u00ae UF) and as a highly active activator (Calsec\u00ae FE) in, for example, bisphenol-cured FKM compounds.<\/p>\n\n

Calsec\u00ae FE is a special type of micronised calcium hydroxide [Ca(OH)2] used in crosslinking of fluoroelastomers. The raw material is regulated under FDA 21 CFR 184.1(b)(1) and is considered generally recognised as safe (GRAS). It may therefore be used in fluoroelastomer compounds intended for food contact.<\/p>\n\n

Calsec\u00ae products are offered in several different forms with different melting points \u2014 for example as gel, powder or pellets. It is recommended to add the raw material at the end of the mixing cycle.<\/p>\n\n

The raw material can be used to manufacture, for example, mould release agents, processing aids, lubricants and dispersing agents. It is used across many industries, but typically in the automotive or pharmaceutical industry.<\/p> <\/div>\n \n \n \n <\/div>\n<\/div>\n
