New Products: MDS launches FFKM line

Comments Email

HOUSTON—Material and Design Solutions has launched a new line of low-compression set perfluoroelastomers (FFKM) compounds for the chemical processing and refining industries.

MDS claims that its new Petroz perfluoroelastomer (FFKM) compounds deliver the lowest compression set in the industry, which improves sealing performance in high-pressure, high-temperature environments throughout extended operating times.

The first grade, Petroz 375, is a is a 75-durometer grade with a compression set of 14 percent after 70 hours at 200C, MDS said. The 90-durometer grade, Petroz 390, exhibits a compression set of 10.5 percent after 70 hours at 200C.

In addition, MDS said that its Petroz compounds offer tensile strength, and flexural modulus that is similar to competing perfluoroelastomers. They also exhibit strong resistance to a broad range of chemical media, according to MDS. These properties make the compounds ideal for o-rings and custom-molded parts such as mechanical seals, pumps and valves, according to MDS.

"The Petroz series sets a new benchmark for compression set performance and specifically helps our customers meet the challenges of high-pressure, high-temperature environments and extended lifetime service requirements," MDS President John Jorgensen said in a statement.

Based in Houston, MDS provides thermoplastic, elastomeric and metal components for a variety of applications in the oil and gas, fluid handling and semiconductor markets. For additional information about its products and services visit
