nspec acquires P84 from UK-based lnspec Group Plc has announced that it has reached agreement to acquire the P84 high-performance polyimide fibres business from Lenzing AG. The deal should be completed in early April. The assets, workforce and management of the P84 business in Lenzing, Austria will be purchased through a new, wholly owned Austrian subsidiary company, Imi-Tech Fibres GmbH. Lenzing AG will continue to provide services and utilities to the new company. In line with Inspec’s strategy of acquiring busi-
nesses with strong technology and growth potential, the long-term lease of an adjacent plot of land for future expansion will form part of the deal. P84 fibres are used worldwide in high-temperature applications, including hot gas filtration and firefighting apparel. Together with the US-based Imi-Tech polyimide foam business, this acquisition will broaden Inspec’s range of polyimide foam applications in a core business area. Imi-Tech Fibres GmbH, A-4860 Lenzing, Austria. Tel: i-43 7672 701 2624, fax: +43 7672 74823.
De-oiler improves aircra environmental performanc Pratt & Whitney (Canada) has placed a development order with Dunlop Aero Equipment for 10 air/oil separation units to be fitted to the accessory gearbox of its new PW.545 engine. Dunlop air/oil separators (de-oilers) utilise the properties of Retimet, a proprietary metal foam material developed for use in air breathing oil systems. Mounted on the rotating shaft, the separator removes the oil from the air/oil mixture or foam and centrifuges it to the periphery of the housing before returning it to the system. Properties such as thickness of the fibres and size
of the cavities are developed for each application depending on diameter and speed of shaft, housing space, and other factors. Already in use on a number of aircraft engines, Dunlop air/oil separators prevent discharge to atmosphere of even very small oil droplets. Of simple construction they provide a high level of reliability and safety. They have been subjected to inverted running and negative gravity test conditions.
