German sealing applications specialist Freudenberg Sealing Technologies introduced several new materials and sealing innovations at the 2019 International Paris Air Show held on June 17 this year.

The innovations are designed to help aerospace customers address ever-increasing safety and performance requirements in the industry.

During the event in Paris, Freudenberg showcased a new high temperature, fireproof material; a new Omegat OMS-CS cap seal; a new ethylene propylene diene monomer (EPDM); and fluoroelastomer (FKM) developmental materials.

“Our aerospace customers strive continuously to be faster, safer and more efficient, which, in turn, requires us to innovate to help them reach those goals – a challenge we enthusiastically embrace.”

Freudenberg Sealing Technologies global mobility sector VP Vinay Nilkanth says the launch of several new products aimed at improved performance underscores Freudenberg’s commitment to being a global leader and development partner to the industry.

Nilkanth adds that Freudenberg Sealing Technologies’ new proprietary fireproof sealing fabric is made to withstand the extremes.

Tested on standard aerospace bulb seals and passing AC20-135 fireproof requirements, the fabric acts as a barrier, providing up to 15 minutes for necessary corrective action. The fabric performs as well as other industry standard solutions but is much more cost effective.

For use in dynamic, reciprocating applications where low friction is required, the new Omegat OMS-CS cap seal is a two-piece rod seal set consisting of an engineered polytetrafluoroethylene ring and an O-ring energiser.

The seal offers low breakaway and running friction, and is chemically compatible with aerospace fluids and greases. It also provides excellent wear and extrusion characteristics, and has angled blow-by notches and lubrication grooves.

He explains that the company’s new EPDM LM426288 material for use in low pressure static sealing to –77 ºC performs well and is resistant to AS1241 phosphate ester hydraulic fluids. The material offers high temperature compression set resistance and short-term resistance to 150 ºC for high temperature hydraulic systems such as hydraulic braking.

The FKM LM426776 material for use in low pressure static sealing to –67 ºC shows excellent resistance to several aerospace media, including jet turbine and gearbox lubricants, high and low aromatic content jet fuels, and fire resistant hydrocarbon hydraulic fluids.

The material offers short-term high temperature resistance to 270 °C and long-term compression set resistance at 200 ºC, he concludes.
