Strong, heat-resistant synthetic fibers. Developed in the 1960s after the creation of nylon. More durable than nylon, it is used for, among other things, reinforcing material for aircraft and seismic reinforcement for structures. It is made by spinning condensed, polymerized metaphenylene isophthalamide (MPIA), which is made from meta-phenylenediamine (MPDA) and isophthaloyl chloride (IPC), into a fiber.
Employed in the FOX Unit's Sneaking Suits in the 1970s.
