Amphenol have chosen Victrex Peek for a high performance wiring, cable, and hydraulic tubing clamp to replace and outperform traditional P-clamps and Saddle clamps.
Originally developed for the new Boeing 787 all-composite aircraft, the new high performance clamps consist of Victrex Peek polymer, a high performance thermoplastic, that is over-moulded with a silicone rubber cushion. By using Victrex Peek polymer, Amphenol was able to develop a lighter and stronger clamp that is completely non-corrosive and non-conductive for use throughout the aircraft.
“Victrex Peek polymers are exceptionally strong, inert, inherently flame retardant, and can be easily fabricated into tight tolerance parts,” said Michael Sandeen, Product and Technical Leader at Victrex. “They offer significant advantages to aerospace engineers looking for lightweight materials that provide processing flexibility, reduce manufacturing costs and provide durability in harsh environments. Victrex Peek polymers have successfully displaced metals, traditional composites and other plastics in a growing number of aerospace applications.”
Amphenol uses a proprietary silicone over-moulding process to produce the high performance clamps, which are also used in a wide range of shipboard, industrial and railway applications. The advantage of Amphenol’s over-mould process is that it bonds the silicone rubber cushion to the plastic. Unlike cushions in metal clamps, they will not detach or come off, thereby reducing the possibility of wire chafing. In addition, because the cushions allow for varying compressions, the same size clamp can accommodate multiple bundle diameters.
