Launching the Trelleborg Sealing Solutions Innovation Award
Materials Development Manager at Trelleborg Sealing Solutions, Jon Cutler, says: “The requirements for seals and gaskets in HyJet and Skydrol applications are extremely demanding. Seals have to withstand high pressures along with wide temperature fluctuations and we have specifically engineered this new EPDM to be best-in-class in these conditions. Extensive long term testing has been successfully undertaken with results that are better than other sealing materials on the market.
“These included back-to-back tests against a leading competitive product that complies with NAS 1613 Rev 5 grade. Our material was significantly better in terms of low temperature flexibility using the measure TR10 according to test method ASTM D1329. In many actuation systems, improved low temperature elasticity provides greater sealing security. More than ever before aircraft are flying higher in colder regions and E8T89 meets the -55 °C/ -65 °F target set by the industry for sealing materials.”
