Ultem polyetherimide (PEI) resin-based composites, foam and fiber materials withstand very demanding and high-heat conditions. These materials can replace metal to achieve weight reduction without sacrificing performance. Ultem composites may be used to make fabric that provides long-term performance, such as for ultra-lightweight aircraft interiors. Ultem fibers provide excellent flame-smoke-toxicity (FST) performance and can be made into flame-retardant fabrics for use in industrial transportation and home furnishings. Ultem foam, which is suitable for machining, vacuum bagging, compression molding, and thermoforming applications, weighs one-twentieth that of Ultem resin and is available in three different densities: 60 kg/m3, 80 kg/m3, and 110 kg/m3.
