New fluoroelastomer–PEEK bonding technique gives stronger bond Precision Polymer Engineering (PPE) has developed a new method of bonding fluorinated elastomers to polyetheretherketone (PEEK). The new technique avoids the complexity normally associated with bonding fluoroelastomers to PEEK, yet produces a bond that is over 180% stronger. Until now, bonding elastomers to PEEK typically involved conventional abrasive treatments, acid etching, laser treatment or plasma techniques to prepare the surface of the engineering plastic, followed by the application of epoxy adhesive. The strongest bonds achieved using these techniques have a fracture force in the region of 1400 newton. The PPE process uses a new surface preparation technique that produces a stronger bond of approximately 4000 newton. The bond strength is such that, in laboratory testing, the PEEK dumb bells used to measure tensile strength begin to elongate before the bond fails. PEEK and fluoroelastomer composites are commonly used in
process engineering, pharmaceutical and semiconductor manufacture. They offer the strength, temperature and chemical resistance of PEEK engineering plastic with the chemical resistance and sealing capability of the fluoroelastomer. Importantly the bonding action achieved between PEEK and the fluoroelastomer compromises neither the physical performance properties nor the chemical resistance of both materials. The new bonding technique is the result of extensive research over the past 12 months through an international collaborative effort involving PPE, some of its customers and polymer scientists. The company considers the bonding technique to be a technological breakthrough that will have a significant effect on the productivity of manufacturing processes.

International Pump Users Symposium moves to Baltimore for 2004 The programme for the 2004 International Pump Users Symposium has been announced, and as usual a considerable proportion is of interest to the sealing community. There is one main lecture, two tutorials, two short courses and two discussion-group topics directly concerned with mechanical seals. The symposium will be held on 8–11 March 2004. The lecture is titled ‘Mechanical seals with wavy SiC faces for a severe duty NGL/crude pipeline application’. It will be presented by Bill Key, Flowserve, Ralph Dickau, Enbridge Pipelines and Bob Carlson of Enbridge Energy. Topical tutorial sessions include ‘Sealing system considerations for pumps used in the water industry’ 4
and ‘Overview of API 682 and ISO 21049’. Short courses available cover ‘Mechanical seal, design and theory’ and ‘Mechanical seal, application and failure analysis’. The discussion groups are generally a participant-driven discussion. The general mechanical seal discussion group meets three times and there is a separate group on seal user/manufacturer alliances. In parallel with the above there will be the exhibition of pumps and pump-related products and services.

Conference news Papers requested for the 13th International Sealing Conference The Fluid Power Association of the German Machinery and Plant Manufacturer’s Association (VDMA), with its Fluid Power Sealing Group is organizing the 13th ISC International Sealing Conference, Sealing Systems for Fluid Power Applications. This will be held on 5–6 October 2004, at the University of Stuttgart, Germany. Sealing Systems have a significant impact on both the functionality and safety of complex fluid power systems, as well as on their environmental friendliness. The motto for the conference will be “Sealing Technology – A Global Challenge”. The call for papers can be downloaded from the conference website, or alternatively by contacting the conference organizers.
