History - COGEBI´s origins
The company “COMPAGNIE GÉNÉRALE BELGE DES ISOLANTS” (General Insulation Company of Belgium) was founded in 1929. The name was shortened to COGEBI. Company was focused on production of components used as insulation materials. Ten years later, COGEBI was the first company in Belgium to perform injection molding of cellulose acetate, which was the only thermoplastic at the time. Beginning of mica processing in Tabor, in the Czech Republic, was in 1937. In 1950 manual production of electric insulation based on mica flakes. The foundation of new plant in Tabor, which worked under the name ELECTROISOLA n.p. in 1951 and five years later (1956) started production of mica paper called Remika by thermo-chemical process. It was revolution in construction of mica insulations. COGEBI started production of mica paper called Cogemica in 1957. In 1963 was setted up a new laboratory in COGEBI, in order to formulate epoxy resins. COGEBI gained a foothold in the North American market by establishing of subsidiary under the name COGEBI Inc. in 1983. COGEBI developed new markets outside the electrical sector and ELECTROISOLA was established as a joint stock company in 1991. COGEBI established COGEBI Chine Ltd. Located in Hong Kong in 2002 and COGEBI Asia in Malaysia in 2005. The COGEBI Group has been acquired by a Russian ELINAR Group, specialized for developing, manufacturing and distribution of electrical and mica insulation materials ELINAR company is leader on their markets. COGEBI established COGEBI PRC in Shanghai. The ELCIM Group holding company- under this company belongs COGEBI and ELINAR (in 2013).

COGEBI philosophy
COGEBI GROUP uses a gift of nature, that why it´s necessary to protect environment. Natural mica has exceptional physical characteristics. It can be found throughout the world, most notably in the presence of Paleozoic rocks. Accessible deposits are located primarily in India, on the American continent, in southern Africa and in Russia. Mica’s chemical composition places it in a group of aluminum silicates.

Two types are extracted - Muscovite, in which there is a predominance of potassium. And the second is Phlogopite, in which the presence of magnesium can be detected. COGEBI has perfected technology that allows the agglomeration of mica fragments to create a homogenous material in continuous production. The COGEBI process subjects the mineral to the action of a highly pressurized water jet, producing flat particles several microns thick, whose physical and chemical properties have been carefully preserved.

The resulting water slurry is fed to a special type of paper machine, which forms a continuous sheet of mica paper. At this stage, there is no need for a binding agent to hold the particles together, because their existing natural intermolecular attraction is usually sufficient. This 100% mica paper is called Cogemica®, and is based on either Muscovite or Phlogopite. And another type of COGEBI’s mica paper is called Remika®, which is based on calcined Muscovite mica. On contrary to Cogemica, flat paper particles of Remika are created by processing mica through thermal delamination. The use of Cogemica or Remika is given by the requested properties of the final application.

Specialization
ELCIM is focusing on fire protection (cable tapes, aircraft flame barriers), high voltage insulation (resin rich tapes, VPI tapes and other complementary insulation products) and industrial applications (induction furnaces, commutator insulation, thermal protection).

Cables
