FFKM increases productivity of semi con plant
NEWS The company is also introducing a new range of Keltan EPDM grades that will be produced with high quality colourless paraffinic oil, instead of yellow paraffinic oil. The first of these new grades, Keltan 4551A, is currently under commercial approval at customers with development code DE 3072 and is expected to be commercially available from September 2008. Test results indicate that the product offers improved efficiency in peroxide curing and is suitable for a wide range of applications including low hardness profiles, hoses, seals and bellows. In addition, it offers new opportunities for coloured products and applications. This is seen as the beginning of a new era for the complete product range as the use of yellow paraffinic oil will be phased out over the next year. Among the benefits is an improvement in peroxide curing. With equivalent compound mixing and rheology, the new grade is able to offer improved peroxide cure efficiency and peroxide loading may be reduced by 30%. Contact: DSM Elastomers B.V.

Momentive introduces clear LSR
M
omentive Performance Materials have introduced the LSR7000 a series of highly transparent liquid silicone rubbers (LSR). The materials offer typically 98% transparency combined with the processing and productivity advantages of an addition-cured, platinumcatalyzed LSR. These features potentially enable manufacturers to reduce manufacturing and assembly cycle times for complex parts. ‘By offering high transparency, high elasticity and easy processing, the LSR 7000 series may help designers and manufacturers to effectively address many of the toughest design challenges they face,’ said Yang Nuo, Pacific electronics marketing manager, Momentive. ‘This material is an excellent example of our strategic focus: we combine our close customer collaboration with our leading research and development capabilities, resulting in quick response to complex industrial needs.’ Recent innovation in optical systems, lightguide applications and mobile phones have increasingly seen liquid silicone rubbers replace materials such as transparent polycarbonate and polymethyl methacrylate (PMMA) in new applications, due to the processing and productivity advantages of LSR. In China, Momentive has 4

cooperated with Sunrex, a leading input device manufacturer, to apply the LSR 7000 series to light guide film for commercial production. ‘By combining our proprietary technology with the super transparency of LSR7000, we have been able to successfully develop silicone light guide film for use in new mobile equipment,’ said Liu Dianshan, director of the Sunrex facility in Suzhou. ‘We are now cooperating on a long-term basis with Momentive to develop new, flexible applications for smart 3D light guide film.’ Contact: Momentive Performance Materials GmbH, D-51368 Leverkusen, Germany.

New, bigger MaxiFit solves OD mismatch problem
V
iking Johnson has extended its MaxiFit couplings range by adding a DN 700 size developed to solve a specific customer problem. The coupling was designed initially to overcome a difficulty encountered by Balfour Beatty during the cleaning and spray-lining of a 30 km section of United Utilities’ Hodder strategic trunk main. The cast iron main dates from the 1920s, is classified as 27” but in practice there proved to be considerable variation in OD, creating difficulty connecting make-up pieces at cut-out points. The 17 mm tolerance of MaxiFit was identified as the answer to the problem and the new DN700 size was introduced in time to meet the spray-lining schedule. The coupling is suitable for use with steel, ductile iron, PVCu, cast iron and asbestos cement pipe materials for a working pressure of 16 bar.

NEWS from seal erosion and compression set caused seal issues in IMD and STI processes. The scheduled maintenance cycle was 90 days but premature sealing issues occurred within 30–60 days. The incumbent O-ring performance issues were related to mechanical as well as chemical attack with plasma erosion. By using Kalrez 9100 parts the 30-day planned maintenance period has been extended to 180 days, depending on seal location. Increased equipment availability has increased production capacity by more than 20%. Contact: DuPont Performance Elastomers SA, 2 chemin du Pavillon, CH-1218 Le Grand-Saconnex, Geneva, Switzerland.

Company News Investment provides facilities for large diameter seal production
J
ohn Crane has recently invested in a modern machining centre to extend its capability to produce large diameter dry gas seal components. The company has experienced an increasing demand for large diameter seals over the last two
September 2008
years. An example is one LNG plant for which they have supplied 50 seals for shaft diameters of 300 and 350 mm in the last year. The market is being driven by the global demand for cleaner fuels and the migration away from coal power. Ethylene plants are also getting much bigger and China are building several new 1000 tons/year trains to satisfy the regions demand for plastics. The compressors are getting significantly bigger to increase capacity and reduce production costs. The new CNC machine has the capacity to manufacture seals parts up to 1.25 m diameter with the technology to be able to sustain the high accuracy required by large diameter gas seal parts. It will allow in-process dimensional checks on critical features in situ, using an on-board probing system. This eliminates the requirement to remove the part from the machine to have it measured externally thereby reducing seal part lead times while maintaining high accuracy. The 5-axis of control also means that many parts for gas seals require only two chucking operations.
n 4 August 1968, the Parker Corporation’s first manufacturing plant for seals in Europe, Parker Hannifin Dichtungs GmbH, was founded in Pleidelsheim, Germany and the plant still predominantly produces O-rings. The operation that started with 30 employees and a production area of 1000 m2 now produces approximately 1.5 million O-rings, back-up rings and precision-moulded parts per day from 300 different standard and special elastomer compounds. Currently the mixing department at the Pleidelsheim plant is being modernised, while an extension of the development and manufacturing areas are on the agenda for the next few years.
