Kalrez® for use in Chemical Processing


Synthetic elastomer's from DuPont Performance Polymers provide dependable long-term service in the chemical processing industry, including petroleum refining, agricultural chemicals, pharmaceuticals and polymer production. In sealing applications that require high heat and aggressive chemical resistance, parts made from genuine Viton® fluoroelastomers and Kalrez® perfluoroelastomer parts deliver increased reliability and safety, extended service life and design flexibility.


Kalrez® can address Sealing Challenges across all Applications

Kalrez® provides reliable, cost-effective sealing solutions throughout the chemical process industries:

  • Chemical production and transport

  • Petroleum refining

  • Agricultural chemicals

  • Painting and coating operations

  • Analytical and process control instruments

In pumps, valves, reactors, flange joints and other equipment, Kalrez® parts - whether they are O-rings, custom shapes or valve stem packing systems - are proving their value year in and year out. Their combination of long-term resistance to chemical attack, swelling and elevated temperatures allows chemical companies to reduce costly seal failures, control fugitive emissions, improve process productivity and avoid contamination of the process stream.

CPI and Power Generation Environments

Viton® is the most specified fluoroelastomer for demanding process environments. For over 40 years, Viton® has been producing reliable, long-term service. Flue duct expansion joints made from Viton® fluoroelastomers perform in high heat and in corrosive flue gases. In order to help assure long-term performance, it is necessary for buyers and construction engineers to specify parts made from Viton®
