~A class-leading high temperature FFKM~
Precision Polymer Engineering (PPE), one of the world’s leading manufacturers of high performance moulded elastomer seals, has developed Perlast® G77X – a perfluoroelastomer (FFKM) sealing material combining high temperature performance with exceptional low compression set.
Perlast® G77X has been engineered for long term performance and durability in a range of critical applications, including chemical processing, aerospace, and in mechanical seals. The material can be moulded into O-rings and custom shapes.
Duncan Frame, Business Line Leader for Strategic Growth at PPE, discussed the benefits of Perlast® G77X as part of the material launch.
He said: “The USP of Perlast® G77X, is its class-leading high temperature performance – up to 350°C, and also with excellent response to temperature cycling effects. When combined with an exceptionally low compression set over extended periods, and the chemical resistance typical of FFKM materials, Perlast® G77X emerges as a strong choice for any critical high-temperature application.”
“With the improvements in performance and reliability expected from upgrading to Perlast ® G77X, our customers can expect to see significant reductions in operational downtime and cost of ownership.”
At the material launch, Stuart Campton, Strategic Market Development Leader for Fluorinated Products at PPE, spoke about how Perlast® G77X complements the rest of the ‘Perlast family’.
He said: “Adding Perlast® G77X as the sixth member of the Perlast family of FFKM sealing materials is a big deal. It means that whatever temperatures or chemistries are involved, PPE can offer a high performance material grade which will exceed expectations. Whether that’s Perlast® G90LT for high pressures and low temperatures, or Perlast® G74S for food contact applications, the Perlast ® family now represents a comprehensive sealing solution when failure is not an option.”
“What’s more, we’ve also tested Perlast ® G77X externally to AMS 7257 Rev E, and the material will be listed on the PRI-QPL database. This compliance is hugely significant to our aerospace customers, as alongside PPE’s Nadcap and AS 9100D audits and certifications, we can give full peace of mind that Perlast® G77X won’t let them down.”
PPE has a deep understanding of the challenges faced by equipment manufacturers and operators in critical high temperature applications. This knowledge feeds into the development of innovative material grades like Perlast ® G77X, which deliver long term sealing performance under temperature extremes, while demonstrating industry-leading low compression set. PPE is always working to develop better performing sealing materials to help customers find those marginal gains in performance, reliability, or economy. The expansion of the Perlast® family with Perlast® G77X is just the latest example.
