Chemraz® combines the resilience and sealing force of an elastomer with chemical resistance approaching that of PTFE. Chemraz solves some of the most difficult sealing problems in natural gas power generators and truck diesel engines while offering outstanding in-use cost effectiveness through reductions in warranty claims and down time. Chemraz resists attack by nearly all chemical reagents, including inorganic and organic acids, alkalines, ketones, esters, aldehydes, alcohols and fuels. As a result, Chemraz, engineered by Greene, Tweed, provides long-term service in virtually all applications where vehicle-operating temperatures are elevated and reduced emission requirements are paramount.
