Challenging Field Environments

Kalrez® perfluoroelastomer parts stand up to severe downhole conditions--from high pressures and temperatures, to aggressive sour gas and corrosive fluids. Downhole conditions can deteriorate elastomers rapidly. Blistering heat, corrosive fluids and toxic gases can destroy the physical properties and sealing performance of other materials. Even under extreme conditions of pressure, heat and man-made chemicals, Kalrez® seals have held up and remained virtually unchanged. Kalrez® has been field-proven across the industry in such applications as:

• Tubing-to-packer seals
• Subsurface safety valves
• Logging boots
• Casing tie-back seals
• Survey tool seals
• Slip-joint seals

Kalrez® is offered in standard or specialty grades that have been formulated to optimize properties and give the best performance in specific applications.

Synthetic elastomers from DuPont Performance Elastomers 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.

Sealing Challenges Across 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
