Greene Tweed

High-Performance Thermoplastic Composite Aerospace Brackets

Lightweight durable parts are an excellent replacement for metal materials Lansdale, PA – Greene Tweed, a leading global manufacturer of high-performance sealing solutions and engineered components, highlights the availability of Xycomp DLF high-performance thermoplastic composite aerospace brackets, which can endure the substantial demands of aerospace environments while offering significant weight savings over metallic parts. Greene Tweed aerospace production components have been flying since 2011 and at 35 to 60 percent lighter than competitive metallic components, the brackets are an excellent replacement for metal materials. Greene Tweed’s proprietary compression molding system provides high performance solutions with increased part complexity. The aerospace brackets, which are used to join structural elements together, provide support, and hold essential components firmly in place, can now be produced in complex-contour shapes for near-net, intricate geometry with molded-in features such as bushings or attachment points.   The material meets fire, smoke, and toxicity (FST) safety requirements for interior aerospace parts, and offers excellent resistance to aerospace solvents, high temperatures, and high vibrations for extended component life.

G57 premium elastomer

Chemraz® G57 is a perfluoroelastomer that Greene Tweed material scientists and application engineers specifically developed to meet the demands of aggressive dry plasma systems and other extremely demanding semiconductor fabrication sealing applications. Chemraz® G57 perfluoroelastomer’s unique formulation provides enhanced plasma resistance and minimal contamination, resulting in less downtime and higher wafer processing yields. Recommended primarily for both static and dynamic oxide etch wafer processing applications, Chemraz® G57 remains stable at service temperatures up to 572°F. Boasting nearly universal chemical compatibility, and the broadest chemical resistance of any elastomeric material, Chemraz® G57 is idea for use across a wide range of sealing applications, including endpoint windows, bell jar seals, valve seals, KF fitting seals, window seals, isolator valve seals, lid seals, gas inlet seals, slit valve seals and chamber seals. Greene Tweed delivers highly customizable solutions guaranteed to provide excellent performance under extremely challenging operating conditions in the semiconductor industry. Its portfolio of advanced elastomer seals and thermoplastic components are found throughout a broad range of mission-critical equipment in key process areas of the world’s semiconductor fabs, including etch, deposition, aqueous and electro-chemical (electroplating).
