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 Viton® fluoroelastomers and Kalrez® perfluoroelastomer parts deliver increased reliability and safety, extended service life and design flexibility.

Viton®

Reliable Performance for Demanding Chemical Processing Applications

Viton® fluoroelastomer features excellent resistance to aggressive fuels and chemicals and has worldwide ISO 9000 registration. It is the sealing solution of choice for demanding chemical processing applications, where reliable performance is critical for safe operations and maximum uptime.

The World's First Fluoroelastomer

Viton® fluoroelastomer is the most specified fluoroelastomer, well known for its excellent (400°F/200°C) heat resistance. Viton® offers excellent resistance to aggressive fuels and chemicals and has worldwide ISO 9000 registration.

DuPont Performance Elastomers has developed many types of Viton® to meet specific end-use and processing needs. There are differences between types of Viton® in terms of chemical resistance and mechanical properties.

Whether your application is chemical processing, automotive or any number of other industrial applications, there is a particular type of Viton® that best meets your specific performance requirements. The general purpose types differ from the specialty types primarily in chemical resistance or low-temperature performance. Among specialty types, products are tailored for superior fluid resistance, low-temperature performance or combinations of these properties.

In order to ensure product integrity and compliance to OSHA 1910.119 in finished parts made of Viton®, look for the “Genuine Viton®” mark on the package. This “mark” signifies that the parts you’re getting have been manufactured and distributed in accordance with strict guidelines established by DuPont Performance Elastomers.

Kalrez®

Proven Performance in the Chemical Processing Industries

For long-term, reliable service Kalrez® perfluoroelastomer parts provide cost-effective sealing solutions. In aggressive chemical or thermally challenging environments, Kalrez® parts have been reducing downtime and extending the mean time between replacements (MTBR) in:

• Chemical production and transport
  
• Petroleum refining
  
• Agricultural chemicals manufacturing
  
• Painting and coating operations
  
• Analytical and process control instrumentation

In pumps, valves, reactors, flange joints and other equipment, Kalrez® parts – whether 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, improve MTBR, control fugitive emissions, improve process productivity and avoid contamination of the process stream.

Kalrez® parts are sold through a global network of authorized distributors who are knowledgeable of sealing applications and the Kalrez® product line. Please contact DuPont Performance Elastomers for the Authorized Distributor nearest you.
