Broad Chemical Resistance at Elevated Temperatures SUPERIOR COMPRESSION SET RESISTANCE With its broad chemical resistance, Chemraz® 555, a perfluoroelastomer, is ideally suited for challenging fluid handling applications. Chemraz 555 provides a significantly wider operational band and superior compression set resistance than any other broad range perfluoroelastomer on the market. With an upper temperature limit of 600ºF (316ºC), it is the elastomer of choice for the most demanding services found in the chemical process and refining industries. Chemraz 555 is suitable for use in a wide variety of media including acids, caustics, aldehydes, esters, ethers, aromatics, hot water, steam, amines, methanol, ketones, TBA, MTBE and mixed process streams.
