Plymouth, Michigan – Simrit, a division of Freudenberg-NOK Sealing Technologies GmbH & Co. KG, said its F273 fuel resistant fluorosilicone material has been approved for the aerospace Qualified Product List (QPL), reports Rubber & Plastics News.
Simrit said it is the first and currently only company approved by the Society of Aerospace Engineers and the Performance Review Institute to manufacture the AMS7273-approved material on the QPL. The approval allows original equipment manufacturers, the US government and airlines to eliminate redundant testing criteria and processes.
Robert W. Keller, materials development manager at Freudenberg-NOK Sealing Technologies, said the F273 material is ideal for fuel control and jet engine companies because of its “excellent performance in extreme heat environments.”
The F273 material is manufactured at the company's Santa Ana, California facility for use in high-performance, high-pressure jet fuel systems and is resistant to jet fuels and synthetic turbine lubricants with a typical application temperature range from -70°C to 200°C. Simrit said it is "ideal" for use in O-rings, moulded shapes and plate seals in fuel controls, as well as valves and pumps on commercial aircraft engine applications.
