Greene Tweed to Showcase Fireproof Hydraulic Seal at Paris Air Show

High performance elastomers and composites to be showcased at Booth No.3 in the UK pavilion at the Paris Air Show

Greene Tweed, a leading global manufacturer of high-performance seals, thermoplastics, composites, and engineered components, announces it will showcase its ground-breaking Fireproof Hydraulic Seal (FPH Seal™) at the 53rd International Paris Air Show, from June 17–23, 2019 at the Exhibition Centre of Le Bourget.

Greene Tweed will also exhibit its Fusion™ 665 ultra-low-temperature FKM elastomer, Chemraz® 676 ultra-high-temperature FFKM elastomer, and Xycomp® DLF® lightweight high-performance thermoplastic composite components at Booth No.3 in the UK pavilion.

Greene Tweed’s FPH Seal™ is the first-ever elastomeric seal stack to pass fireproof testing for fireproof-rated equipment (1093°C/2000°F minimum average for 15 minutes), making it an ideal choice for thrust reverser actuator systems (TRAS), fuel systems, and thrust vectoring/nozzle systems.

Using standard aerospace glands in accordance with AS4716 and AS5857, the new FPH seal™ provides excellent high- and low-hydraulic pressure sealing in static applications.  Traditional fire shields are typically heavy, bulky, easily damaged, costly, and they require assembly. The FPH Seal™ offers an excellent alternative.

Stop by the booth to see Chemraz® 676, an ultra-high-temperature and highly chemical-resistant perfluoroelastomer (FFKM) elastomer material specifically formulated to meet and exceed Aerospace Material Specification (AMS) 7257E requirements. With industry-leading compression set properties and a maximum operating temperature of 615°F/324°C, Chemraz® 676 is an ideal choice for engine and fuel manifold applications, where high temperatures and aggressive chemicals combine to shorten the life of standard elastomers.

Also, on display is Fusion™ FKM 665, a new generation, ultra-low-temperature and chemical-resistant elastomer, specifically formulated to meet and exceed AMS 7379 and AMS-P-83461 requirements. With a temperature range of -70°F to 450°F (-57°C to 232°C), Fusion™ 665 achieves outstanding low-temperature performance without compromising high-temperature performance.

Visitors to the booth can also see Xycomp® DLF® high-performance thermoplastic composite structural components, which offer the performance of metal at a fraction of the weight. Xycomp® DLF® composite materials were developed to enable replacement of complex-shape metal components on aircraft. With outstanding fatigue, vibration, and impact resistance, Xycomp® DLF® provides up to 60% weight savings to help reduce emissions and fuel burn while providing exceptional performance.
