Victrex has introduced Victrex PEEK HMF polymers based on the Victrex 90-Series formulation which has primarily been used to mould tough, thin-wall parts, which will be showcased at JEC Europe, Porte de Versailles, Paris, France, next week.
“Lightweight thermoplastics such as Victrex PEEK HMF polymers not only can help engineers reduce component weight by up to 80% when compared to metals like steel and brass, but offer an equivalent stiffness and strength proving that our materials are just as capable as the metals they are replacing,” explained Stephen Dougherty, Strategic Marketing Manager. “These weight reductions and mechanical properties can potentially lead to efficiencies that were not attainable in the past,” said Dougherty.
According to Victrex, converting aluminium brackets, clips, fasteners and other secondary structures to its PEEK HMF polymers can help reduce the lifetime costs of an airplane. Using current fuel prices, removing 100 lbs. (45 kg) of weight can save airlines up to $4,500 in annual fuel costs per aircraft. Besides fuel savings, accurate and speedy assembly is crucial to aerospace engineers. In addition to the ability to consolidate parts with highly functional designs, it says its PEEK HMF grades can also help shorten cycle times and reduce production costs because of the efficiencies gained through the injection moulding process. These benefits help the entire supply chain by getting lighter, easily installable parts to manufacturers faster, ultimately leading to more fuel efficient airplanes getting off the assembly line quicker.
In addition, as service expectations increase for airplanes and industrial equipment, the specification of materials is critical to ensure safe and reliable operation with minimal maintenance required.
Victrex explains its PEEK HMF polymers have been tested in a range of chemicals including: hydraulic fluid, jet fuel, oil, grease, lubricants and other service fluids. These are environments that would undermine the longevity of many other metals and plastics. In combination with excellent fatigue performance and a long term use temperature of 500°F (260°C), Victrex’s PEEK HMF polymers have been used as a reliable metal replacement solution for applications found in some of the harshest environments.
Victrex can be found at booth J11.
