Apart from its unique performance properties and environmental benefits the Victrex PEEK-based honeycomb provides numerous other advantages including excellent impact resistance; unlike an aluminium or thermosetting honeycomb, PlastiCell's honeycomb will not remain deformed by accidental impacts during machining or assembly of the part and, due to the material's high temperature performance, the honeycombs can operate continuously up to 220°C (428°F, a thermoformable honeycomb core allows for the production of parts with short cycle times using an autoclave-free process. There is no size constraint as it is possible to make an endless honeycomb using PlastiCell's manufacturing process. Part size limitation is dictated by the hydraulic press platen size.
