Cable insulation fire-retarding composition PENOTERM-К

It serves as a high efficiency fireproof coating for cable insulation which becomes active under the impact of heat. The developed original composition is deposited in 2-3 movements until at least 0,6 mm coating source layer is formed. Under the influence of high temperature the coating is transformed into a thick multi-centimeter heat insulating layer.
