Made of Nomex III fibers (mixture of thermo-resistant and infusible aromatic polyamides) and with no asbestos fibers. With normal service conditions, physical properties stay unchanged under several hours at 260 ªC, withstanding as well 370 ºC when its degradation starts. When approached to flame, they do not melt, but instead they get scorched making a crust allowing protection. Can be used as well to handle sporadically items stored under nitrogen vapour phase (-180 ºC). Resistant to bases, acids and organic products but not to large exposures to some concentrated inorganics acids. Available in 30 cm long or 52 cm long. According to EN 407 y EN 388 standards
