Sulfones are amorphous engineering thermoplastics noted for high heat-deflection temperatures and outstanding dimensional stability.

Polyester resins, in thermoset, glass fiber-reinforced formulations, have been used for a variety of industrial, marine, and consumer products for at least 40 years.

Extremely wide variations in forms and in physical and mechanical properties are available in polyurethanes.

Polyphenylene sulfide (PPS) is a crystalline, high-performance engineering thermoplastic characterized by outstanding high-temperature stability, inherent flame resistance, and broad chemical resistance.

Many new materials have been developed, but steel remains the principal construction material for automobiles, appliances, and industrial machinery.

Liquid-crystal polymers are a unique class of wholly aromatic polyester poly mers that provide previously unavailable high-performance properties.

Tin is characterized by a low-melting point (450°F), fluidity when molten, readiness to form alloys with other metals, relative softness, and good formability.

Zinc, a crystalline metal with moderate strength and ductility, is seldom used alone except as a coating.

Epoxy polymers are cured to form thermoset resins by either homopolymerization of epoxy groups with themselves, or reaction with curing agents such as anhydrides, amines, and novolacs.

Some degree of compromise is almost always necessary in designing plastic parts.

Available both as thermoplastic and thermoset resins, polyimides (Pls) are a family of some of the most heat and fire-resistant polymers known.

ThermoplasticsStarting with billions of molecules of monomer in a reactor, heat and pressure are applied in the presence of catalysts, causing one of the monomer double bonds to rearrange into two "half-bonds," one at each end.

Specifying powder-metallurgy (P/M) parts and their consolidation process used to be a simple process: Design the part, select the metal powders and lubricants that provide the required properties, compact the powders into a briquette, and sinter the briquette into its finished form.
