TEWKESBURY, England—Trelleborg A.B. has released three new Isolast high specification perfluoroelastomer (FFKM) products, and also launched a new interactive e-learning tool to train Elastopipe installers.
Isolast J9554 was developed to address high temperature steam performance to reach maximum chemical resistance in a high-pressure environment, according to Product Manager Chris Busby. The firm said the compound has a high level of thermal and chemical resistance, as well as to hot water and steam in aqueous environments.
"What we were looking for was essentially retention of physical properties, tensile strength and compression set resistance even when exposed to these very aggressive environments," Busby said.
The compound is developed as a sealing solution compatible with a wide range of chemicals and temperature ranges, with a resistance range from 14° to 527°F, and allowing excursions up to 572°F. "For a lot of high temperature FFKMs, those materials that are used for this type of temperature range, because of the way they are cured … they're not suitable for hot, aqueous environments," Busby said.
On top of a wide temperature range, the compound was developed to perform in applications involving hot steam. In such environments, J9554 holds onto its tensile strength and compression set retention, as well as its elastic recovery, he said. It is suited to applications where high thermal stability and resistance to aggressive wellbore chemicals, steam and acids are necessary for seal performance.
It is particularly aimed at enhanced oil recovery operations, in applications such as thermal recovery and chemical injection to increase the amount of crude that can be extracted from an oil field. It also has industrial applications, including downstream refining, chemical plant processing, mechanical seals, flow regulation and valve equipment coupling.
Aimed at a wholly different market, Isolast J9538 was developed to provide an FFKM with greater mechanical properties for use in food, beverage, healthcare, medical and pharmaceutical processing applications.
"You have a fairly dynamic application, so the seal is not static," Busby said. "It does have some dynamic movement, which means the seal would obviously need a much higher level of mechanical robustness in terms of its capabilities."
