U.S.-based Greene Tweed (UK Pavilion Booth 3) is showcasing its high-performance seals, thermoplastics, composites, and engineered components this week at the Paris Air Show. These include its new fireproof hydraulic seal, the first elastomeric (synthetic rubber) seal stack to pass fireproof testing for fireproof-rated equipment.

Its fireproof seal provides excellent high-and low-hydraulic pressure sealing in static applications, and is an excellent alternative to heavy, bulky, easily damaged and costly traditional fire shields, the company said. Chemraz 676, an ultra-high-temperature and highly chemical-resistant perfluoroelastomer elastomer material, is designed for engine and fuel manifold applications and formulated to exceed Aerospace Material Specification 7257E requirements.

Also on display is the Fusion 665, a new generation ultra-low-temperature chemical-resistant elastomer, which exceeds AMS7379 and AMS-P-83461 while still delivering excellent high-temperature performance.

Xycomp DLF lightweight, high-performance thermoplastic composite components offer the performance of metal at a fraction of the weight, and allow replacement of complex-shape metal components on aircraft, Greene Tweed said.
