Thermoplastics for aircraft interiors

By Staff | September 2007

GE Plastics (Pittsfield, Mass.) has launched three new resins designed for use in aircraft interiors. Noryl LS6010 is a polyphenylene ether (PPE) that has a specific gravity of 1.1, which is one of the lowest available for thermoplastics used in aerospace. It also features low smoke, good durability and nonhalogenated flame retardance (FR). Applications include rub strips and seat track covers, for which low smoke propagation is mandated. Lexan FST9705 is a polycarbonate (PC) copolymer said to be suitable for personal service units, window reveals and bezels, and offers full flame/smoke/toxicity compliance, including OSU 55/55 heat-release performance. Flame-retardant Ultem 9085 is a polyetherimide (PEI) resin that is said to offer better flow and ductility than GE’s Ultem 9075 resin and can reduce part weight by 5 to 15 percent via thinner walls. The material also provides the highest modulus of any Ultem resin grade. Potential applications include decompression grilles, window reveals and personal service units. 1197
