Kulpsville, PA. 21 June 2019. Greene Tweed, a leading global manufacturer of high-performance seals, thermoplastics, composites, and engineered components, announces it will showcase its groundbreaking Fireproof Hydraulic Seal (FPH Seal™) at the 53rd International Paris Air Show, from June 17–23, 2019 at the Exhibition Center 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 #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.
