Green Tweed

• Used primarily in o-rings and other sealing elements; other applications include boots for connectors
• Characterized as having the highest chemical compatibility & temperature resistance of all elastomers, up to 615°F/324°C

• Polyetheretherketone (PEEK) and fluoropolymer (PFA)-based line of composites
• Used as a metal replacement in rotating equipment, e.g., pumps
• Excellent wear and friction properties along with superior non-galling and non-seizing performance and exceptional chemical resistance

– Thermoplastic Composite WR® 300 is a carbon-fiber reinforced compression molded PEEK frequently selected by pump manufacturers and users for pump bushings and case or impeller wear rings. Maximum service life is achieved in clean, lubricated, and/or moist environments.

– Thermoplastic Composite WR® 525 is a thermoplastic composite consisting of carbon fiber in a PEEK matrix. Because of its unique thermal expansion properties, WR® 525 is ideal for use as impeller wear rings, bushings and case wear rings.

• AR^@ is a high-strength material with nongalling and nonseizing characteristics. It allows the use of closer running clearances so internal recirculation is restricted and pump performance improved.
• AR^@ thermoplastic composites have excellent wear, abrasive, and self-lubricating properties to withstand intermittent dry run conditions.
• The combination of closer clearances and the unique properties of AR^@ reduce vibrations and dramatically decrease repair cost.

Abrasive-Resistant Thermoplastics AR®HT is a proprietary thermoplastic material specifically developed for use as bushings, bearings and wear rings in pumps handling abrasive media up to 250°F (120°C). AR®HT provides outstanding chemical, thermal shock and impact resistance, making it a better wear material than traditional rubber, ceramic or bronze materials.

A highly fluorinated elastomer compound, provides excellent chemical compatibility over a wide range of temperatures, -76°F to 450°F (-60°C to 232°C). Recommended for applications demanding a combination of low-temperature properties and chemical resistance, Xyfluor® 870 reduces overall cost, as compared to standard fluoroelastomers, PTFE, and graphite, by extending equipment service life.

• Tetrafluoroethylene propylene (FEPM)

Fluoraz® FEPM elastomers deliver excellent chemical resistance against acids and bases such as methanol, amines, ammonia, urea, hydrochloric acid, and steam at temperatures up to 232°C (450°F). Fluoraz® is generally not recommended for aromatic hydrocarbons.
