The Arcotex 20 ST is an insulating material which is designed with top compression and has a mechanical resistance performance. The resistance to thermal shock ranges up to 500°C with a maximum of 700°C. This is suitable for intense accuracy mechanical production. It also ensures complete self-support and rigidity. This device serves as a solution for problems with high mechanical resistance in the presence of temperatures which can only be guaranteed through the used of asbestos-based sheets.This device is useful for lagging, heating, pressing for the thermosetting and rubbers. It can also be applied for heat shields, thermo-insulating articles and dielectric insulation, and other relevant applications.
