Chemraz® 555
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 600°F (316°C), Chemraz® 555 is the elastomer of choice for the most demanding services found in the chemical process and refining industries and semiconductor SubFabs. 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. Chemraz® 555 is one of Greene Tweed’s many cost-effective products and services that extend the reliability and life of our customers’ equipment in hostile conditions while protecting the public and the environment from unwanted emissions. Chemraz® 555 is available in o-rings, gaskets, and many other custom shapes.

Features and Benefits
