PPE introduces new perfluoroelastomer

ERJ staff report (LMH)

Blackburn, UK - Precision Polymer Engineering has introduced a new perfluoroelastomer called Perlast G75TX, which the company said offers excellent chemical resistance and ultra-high temperature stability.

PPE said G75TX is resistant to temperatures up to +327°C (+621°F) and has a compression set of just 8 percent, which significantly increases the efficiency and lifespan of the seal in pumps and valves. In a 31 July announcement, the company said rapid gas decompression (RGD) resistant grades of the perfluoroelastomer are currently in development.

Perlast G75TX is the latest addition to PPE's high performance, oilfield-sealing materials portfolio which also includes the EnDura range of elastomers developed specifically for oil and gas applications.

“Many companies have tried to improve the high temperature performance of perfluoroelastomers but this has been achieved at the cost of severely undermining the elastomer's mechanical properties, especially compression set,” said David Holt, business development director, PPE.

He added, “Perlast G75TX is the first perfluoroelastomer to achieve ultra-high temperature resistance while still preserving its mechanical performance.”

Perlast G75TX is suitable for both dynamic and static applications, PPE said. And it can be fully moulded into O-rings in any size up to 2m/6.5ft internal diameter, and custom shapes.
