Greene Tweed CHEMRAZ® 505 Perfluoroelastomer
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Chemraz® 505, a perfluoroelastomer, provides a broader range of chemical resistance than any other compound on the market. With a temperature range of -22°F to 446°F (-30°C to 230°C), Chemraz 505 is the elastomer of choice for more than 90 percent of the most demanding services found in the chemical process and refining industries. Chemraz 505 is ideal for processes taking place in subzero temperatures as well as for use in multi-substance plants or in mixed media due to its broad chemical resistance. Chemraz 505 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, aromatics, hot water, steam, amines, methanol, ketones, TBA and MTBE. Applications: Mechanical seals Valves Pump Housings Sampling/metering equipment Compressors Reactors Mixers Controls/instrumentation Sprayers/dispensers Couplings Information provided by Greene Tweed.
