Poly(amide-imide) Polymers - Properties, Processing Techniques, and Bearing Performance,

The properties offered by polyamide-imide molding resins allow design engineers to consider plastics for applications formerly considered too severe for polymers, and allow plastics to penetrate markets for fluid valves, bearings, gears, and other functional parts which until this time, have primarily been the province of metals. In addition, these resins can offer a practical substitute for other plastics which must be replaced as the conditions under which they must perform exceed their inherent capabilities. MM
