Victrex has launched Victrex PEEK 90HMF products, for complex geometries with thin cross sections or long flow lengths where higher strength in a static or dynamic system is required.
The new product comes in two grades, Victrex PEEK 90HMF20 and Victrex PEEK 90HMF40, containing 20% and 40% respectively of carbon fibre filler. These new products are based on Victrex’s High Flow resin and use a unique technology that Victrex says ensures the new grades retain all of the inherent properties of Victrex PEEK, whilst adding stiffness, strength, toughness and durability.
Victrex PEEK 90HMF compounds are designed to deliver high fatigue performance, strength, modulus, and toughness, while retaining the inherent properties of low creep, coefficient of thermal expansion and chemical resistance to aggressive environments of standard Victrex PEEK grades, and they are intended for applications in the aerospace and automotive industries, or industrial machinery equipment.
“The launch of these new grades and compounds is a demonstration of how Victrex strives to address specific market demands,” said Mark Maddern, Global Product Manager at Victrex plc. “We identified a need for increased strength and fatigue performance at higher temperatures, and designed a solution accordingly. By applying a unique processing and compounding approach to our existing and industry-leading Victrex PEEK materials expertise, we have developed the Victrex PEEK 90HMF grades. This unique carbon fibre-based Victrex PEEK product has exceptional properties, delivering unrivalled stiffness, strength, toughness and most significantly, improved fatigue performance at high temperature.”
Recommended moulding conditions for both of the new grades include: dry before use, 3h at 150ºC or 2h at 160ºC; cylinder nozzle temperature, 380ºC; tool temperature, 190ºC; injection speed: medium/high.
Revolution Fibres has collaborated with Mitsubishi Gas Chemical Company to develop a next-generation nanofibre interleaving veil for improving the toughness of carbon fibre composites.
