High temperature perfluoroelastomers

High performance seals specialist Precision Polymer Engineering has expanded its range of perfluoroelastomers to include a high temperature resistant grade

Until now perfluoroelastomers have suffered from poor chemical compatibility performance at the upper limit of their operating temperature range of 310-320C.

In a move to broaden the application of Perlast, PPE has improved the physical performance of its current Perlast grades to offer superior compression set performance at higher temperatures.

The company also reports that detailed trials of the high temperature Perlast indicate the elastomer retains its chemical compatibility at temperatures up to 325C, and allows short excursions to 330C without loss of compatibility.

Precision Polymer Engineering Perlast business manager David Holt believes the high temperature Perlast will broaden the scope of applications of elastomers in extreme environments.

"This high temperature grade of Perlast offers engineers a material whose chemical-resistant characteristics will not diminish even when exposed to elevated temperatures," he said.

The new high temperature grade is the latest in the Perlast range which includes FDA-compliant grades for pharmaceutical and food manufacture and pure Perlast grades used in semiconductor manufacture and biochemical production.
