Chemraz® 505
Universal Compound

Sealing Solutions
Greene Tweed’s Chemraz® 505, a perfluoroelastomer, provides a broad range of chemical resistance, and is available for use as o-rings, gaskets, and many other custom shapes. Because of its versatility, Chemraz® 505 is often used as a standard compound and can be found in a variety of applications, including acids,caustics, aldehydes, esters, ethers, aromatics, hot water, steam, amines, methanol,ketones, TBA, and MTBE. With a temperature range of -22°F to 446°F (-30°C to 230°C), Chemraz® 505 is ideal for processes in subzero temperatures and for use in multisubstance plants or in mixed media due to its broad chemical resistance

Applications
• Mechanical seals • Sampling/metering equipment
• Valves • Mixers
• Pump housings • Controls/instrumentation
• Reactors • Sprayers/dispensers
• Compressors • Coupling
