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), 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. Chemraz 555 is one of Greene, Tweed’s many cost-effective products and services that extend the reliability and life of our customers’ equip- ment in hostile conditions while protecting people and the environment from unwanted emissions.

Chemraz 555 is available in O-rings, gaskets and other custom shapes.
