Nextel fibers - High-temperature insulation (alumina-based fibers)
Official distributor 3M France
ELIT is the official 3M France distributor for Nextel fibers and fabrics, alumina-based technical materials offering excellent resistance in high-temperature environments.
Although Nextel products are sometimes referred to as "ceramic fibers" in everyday language, they do not belong to the regulated or prohibited families of refractory fibers.
Available in continuous fibers, technical fabrics, tapes and braided sleeves, Nextel solutions are a high-performance, stable and perfectly compliant offering, adapted to the thermal requirements of the most demanding industrial sectors.
