    stone of Lanxess success. With the acquisition of the elastomer business from Royal DSM Nv two years ago and the creation of the new Keltan Elastomers business unit, with its head-quarters in Sittard-Geleen, Lanxess has become the worlds leading producer of EPDM rubber, said Werner Breuers of the Lanxess Board of Management.

    Gnther Weymans, head of the Keltan Elastomers business unit, added: The opening of the new headquarters of our still young divi-sion marks the beginning of a new era for us. The next chapter of our global success begins in Sittard-Geleen. The innovative environment that already exists at the Chemelot Campus offers us optimal conditions to continue to build on our global success. The new headquar-ters also underlines our clear belief in this site.

    We are very proud that Lanxess has chosen the Chemelot Campus as the location for the new headquarters of its Keltan Elastomers busi-ness unit, and has been able to complete the project within only 12 months, said Bert Kip, Managing Director, Chemelot Campus.

    Lanxess most recent investments here show that the Chemelot Campus offers the chemical industry ideal conditions for research and develop-ment, and the production of innovative products.

    The company says that it is investing E12 million in the Dutch site to convert 50% of its EPDM production capacity to Keltan advanced catalyst elastomers (ACE) technol-ogy. With ACE the amount of energy required for production processes can be significantly reduced compared with conventional technolo-gies. The technology also makes it possible to manufacture new types of EPDM rubber.

    The material produced at Sittard-Geleen is used mainly in the automotive industry, con-struction sector, and in industrial and electronic parts. In vehicles, the synthetic rubber which is characterised primarily by its resistance to heat, oxidation, chemicals and weathering, as well as its good insulation properties is used for everything from seals in car bodies to parts, such as coolant hoses, in engines.

    In the construction sector, EPDM rubber is also used primarily as a sealing material in profile seals for windows and doors, as a mate-rial to seal joints, for rubber sheets to cover flat roofs or in gaskets for roof structures made of plastic sheeting. It is also used in bathroom fix-tures and other domestic applications, includ-ing the gaskets on washing machines.

    The company is currently investing 235 mil-lion in the construction of a EPDM plant in Changzhou, China. This facility, which is scheduled to begin operating in 2015, will be capable of producing 160 000 metric tons of EPDM annually. The project will create up to 200 new jobs.

    Since late 2011 Lanxess has been producing Keltan Eco claimed to be the worlds first bio-based EPDM rubber at its site in Triunfo, Brazil. It uses ethylene produced entirely from the renewable raw material sugar cane.

    AJI courses improve joint-integrity work done by engineers

    In the UK, the Academy of Joint Integrity (AJI), part of the Flexitallic Group, has revealed survey results in which 100% of engineers respond-ing agreed that the unique use of the Flexitallic Sustainable Training Unit (FSTU) in courses, both enhanced their training experience and helped to improve the joint-integrity work they carry out.

    The AJI makes use of two FSTUs the only units in Europe to enhance its joint-integrity courses through hands-on training. The FSTU enables the user to tighten a bolted joint and see the impact of tightening procedures, on-screen, by using load-monitoring software.

    Gary Milne, Group Technical Training Manager, said: The AJI is the only training organisation to employ the FSTU. It is a fantas-tic tool for both the trainer and the candidate.

    The trainer can easily convey the complex interactions of the flanges, bolts and gasket, whilst the candidate can clearly see the impor-tance of following correct procedures. Our survey verifies that essential training is greatly enhanced for our engineers with the additional hands-on experience they gain with the FSTU.

    Sixty engineers from SABIC Europe recently attended AJI courses including the FSTU. Lee Allcock, Assistant Technical Engineer, SABIC Europe, commented: During our recent train-ing sessions, the FSTU rig was particularly effective at demonstrating the inconsistencies when using hand spanners. FSTU demonstrates the significant variance in load distribution and also shows how far an experienced technician can be from achieving the prescribed bolting stresses to ensure a leak free joint.

    FSTU is an invaluable piece of equipment to effectively demonstrate the importance of a controlled tightening technique.

    The unit uses both an API ring type joint and an ASME B16.5 raised face flange. The two flange arrangements are fully interchange-

    able and give the client direct experience of tightening the full range of gaskets, including solid metal, ring type joints, spiral wounds, Kammprofiles and soft gasket types.

    Key to the units appeal, says the AJI, is the immediate feedback provided by the load-mon-itoring software. This automatically displays data on bolt stress, gasket compression and torque-pre-load relationships in real time, in an easily understandable layout. The software takes the calculation and guesswork out of interpret-ing results and the data-logging facility can be used to capture data from experimentation or record the results of each students performance. This is beneficial when the client requires evi-dence of competence.

    Using this unit, training instructors dem-onstrate the effects that different gaskets and assembly techniques can have on a gasketed joint assembly. Using hands-on training, stu-dents can easily see for themselves the impor-tance of correct assembly techniques, adequate gasket compression, the effect of creep relaxa-tion on gasket performance, and numerous fac-tors affecting the torque-pre-load relationship, including lubricant selection, application, and standard wrench usage.

    Ad-hoc experiments can be devised and con-ducted to answer questions concerning specific plant applications. Direct comparisons between different gaskets, fastener lubricants, and other materials are also easily accomplished using the FSTU.

    Nordson EFD celebrates its 50th anniversary

    Precision fluid-dispensing and fluid-management systems company Nordson EFD, says it is celebrating its 50th anniversary throughout 2013 by participating in numerous trade shows in North America and worldwide, through a global advertising and pub-lic relations campaign, and special cus-tomer incentive programmes.

    According to the firm, which is based in East Providence, Rhode Island, USA, thousands of manufacturers throughout the world use its dis-pensing equipment to apply controlled amounts of adhesives, lubricants and other fluids used to assemble a wide variety of products ranging

    from small medical devices and mobile phones to commercial aircraft.

    This year marks 50 years of commitment to developing innovative technologies that help our global customers build their own products better, faster and more cost-effectively, said Ken Forden, Vice President and General Manager, Nordson EFD.

    The recent enhancements to our Pico dis-pensing systems are a good example of our focus on understanding and anticipating the fluid management needs of the companies and industries we serve. We have more than tripled their speed so they can operate continuously at up to 500 cycles per second making them the fastest piezoelectric valves in the industry. This will help high-volume manufacturers, which continuously run their production lines, make more product in less time than ever before.

    EFD was founded in 1963 and after years of steady growth was acquired by the Nordson Corp.
