Greene, Tweed’s Engineered Components are composite / thermoplastic parts generally used to replace metallic parts in severe service environments. These materials provide performance properties related to wear and chemical resistance. Additional advantages include improved reliability, efficiency gains, and impact resistance in harsh environments. Some examples of components currently being used are wear rings, bearings, and bushings for centrifugal pumps, labyrinth seals for centrifugal compressors, and wafer handling components for semiconductor fabrication. These materials can be provided as individual finished parts, turnkey assemblies, or in tubes / rods / plates for finish machining onsite.

The WR® family of materials consists of compression molded and fiber placed composites and thermoplastics. These materials are carbon fiber reinforced PEEK and PFA-based for superior performance when compared to metallic or other polymeric materials. WR® materials are primarily used in centrifugal pumps and offer the best-in-class wear and chemical resistance for wear rings, bearings, and bushings.
The AR® materials consists of compression molded PEEK and PTFE-based materials specially formulated for prolonged life while operating in abrasive-containing fluids. AR® materials are primarily used in centrifugal pumps and offer the best-in-class abrasive resistance for bearings, bushings, and wear rings.
ONX® is a carbon fiber reinforced, PFA composite. A special cleaning process for finished parts makes this material ideal for semiconductor manufacturing components. Other material features include excellent chemical resistance, low level electrical resistivity, and mechanical property retention at high temperatures.
Arlon® materials are PEEK-based materials specifically formulated to take advantage of the natural wear and corrosion resistance of the thermoplastic. These materials can be compression molded, injection molded, or extruded for a broad range of design flexibility. Arlon® is provided in finished parts, complete assemblies with other components, or in stock shapes such as rods, plates, or tubes.
