CDI Launches Custom-Formulated Base Resistant Elastomers

CDI Energy Products (CDI), a global provider of high-performance polymer products, has launched its new custom-formulated Base Resistant Elastomers (BREs). BREs were initially created to serve the energy market for critical downhole applications. The BRE material development process was driven in collaboration with a long-term CDI energy market partner. Through its product development programs, this initial customer-specific opportunity evolved into a set of nonproprietary materials available to all customers.

BREs have steam and base resistance similar to tetrafluoroethylene propylene (TFE/P or FEPMs such as 100H Aflas). Through a coordinated development effort with a global customer, CDI formulated and produced two grades of the BRE, bonding grade and packer grade (903BG and 903PG). According to CDI, these compounds offer better low-temperature properties and lower compression set than 100H Aflas (FEPM) and fill a gap between an FKM-2 and FEPM-1 (100H Aflas).

“Original equipment manufacturers (OEMs) continue to push the boundaries of performance with superior valves, pumps, compressors, and other critical service equipment. Application-focused materials research and development is a critical element of the success we share with our customers, across markets that include oil and gas, fluid management, power generation, aerospace, gas compression, and many other segments,” said Tim Bremner, materials technology director at CDI. “Establishing application-specific formulations require a comprehensive development process, including material testing, suitability for manufacturing, and prototyping or field testing under conditions as close as possible to the real-world environment. Our customers cannot compromise on quality or safety, and therefore our materials must meet the highest standards before deployment in the field.”

The recommended applications for BREs include bonded seals requiring excellent bond strength in extreme environments, (+400°F steam for example), and in S-seals, T-seals, or V-rings, requiring high modulus BRE where elongation over a typical value of 80% is not necessary.
