產品說明

Greene, Tweed's Chemraz® 505 a perfluoroelastomer, provided a broad range of chemical resistance. Chemraz 505 is available for use as O-rings, galskets 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 taking place in subzero temperatures as well as for use in multisubstance plants for in mixed media due to its broad chemical resistance.
