eveloped specifically to meet the sealing challenges of today’s cylinder makers, Freudenberg Simrit GmbH & Co Kg’s NOK U641 and NOK UH05 materials help engineers extend seal life in various applications. When incorporated properly, these materials provide 8000 to more than 10 000 hours of running time in the field without failure, claims the company. ‘Industry challenges, such as temperature and hydrolysis resistance, and bio-friendly fluid compatibility, will consistently drive the need for more robust sealing technology,’ commented Joel Johnson, Vice President of Technology, Simrit. Customers who are currently using Disogrin 9250 could instead use NOK U641 urethane as an alternative material, explains the firm. It is resistant to hydrolysis and glycol, and increases the long-term operating temperature of a system to 110°C, with standard and biodegradable hydraulic oils. It also can be run in the same tooling as Disogrin 9250. In addition, using a NOK A505 NBR rod seal (with proper back-up) and a U641 buffer has the potential to double system service-life. Also resistant to hydrolysis and glycol, NOK UH05 urethane can be used at 120°C, with standard and biodegradable hydraulic oils. In particular, seals made from the material have been used successfully in hydraulic cylinders exposed to extremely harsh conditions. According to Simrit, it is rare for a material to have properties that enables it to be used at both high and low temperatures. Traditionally, a manufacturer would require two different sealing packages for each application. Using a NOK UH05 (buffer) in combination with a NOK G928 HNBR rod seal (with proper backup) can double the service life of a system at 120°C, but also enable it to operate at an exceptionally low temperature.

relleborg Sealing Solutions Germany GmbH has launched an improved version of Isolast J9440. Compatible with most media, this perfluoroelastomer sealing material now has a higher operating temperature – from -7°C to +240°C – and is accredited to the USP Class 6 standard for use in the pharmaceuticals, medical and health care industries. ‘Developed for high-volume applications in the industrial, chemicals, pharmaceuticals and process industries, Isolast J9440 gives unbeatable value to our customers,’ said Muzaffer Sheikh, Product Manager, Isolast. ‘It is engineered to provide a balance between performance and cost. Over the past 18 months we have seen this material adopted by a number of leading manufacturers – winning significant approvals from them. Now with this improved formulation, we expect to see more.’ The compound is used to fabricate all sizes of O-rings, and is available as gaskets, moulded parts or rubber-to-metal bonded components. It is also suitable for use in the lacquer, paint and coating industry, chemical processing systems, cleaning agent dispensers, pumps, valves, powergenerating equipment, refineries and semiconductor applications.

I
have just attended the Technical Advisory Committee meeting for the 21st International Conference on Fluid Sealing. Among the problems concerning the committee was one that we were quite happy to be presented with – and that is how to squeeze the varied selection of what appear to be good quality papers into the two days set aside for the event. I think that we can promise a busy and interesting time at the conference. There is also quite a good balance between theoretical and practical papers. Not only is this the 21st conference, it is also 50 years since the first conference was held at Canterbury, UK, in 1961. This also will be celebrated with a review of conference highlights, both technical and personal. So, if there are any particular highlights that you remember, whether a technical presentation or one of the social gatherings, do please send me a brief note so that we can include it in our highlights section. We already have a recorded contribution from one of the authors present at the first conference. This contribution was a timely reminder of just how far sealing technology has progressed in the past 50 years. Which got me thinking ... from a quick count, the conference in October will be the 17th in the series that I will have attended. I would be interested to learn who has attended the most conferences in the series – so if you, or someone you know, has attended this many, or more, please let me know. And while we are thinking of technical progress, it is now six months since this newsletter went entirely digital. Quite a lot of newsletter readers that I meet comment on the content, and often on my comments on the content, but I have not received any comments on the transfer to digital only. I will admit to having been slightly concerned about this change, but it seems that we have all learned to adapt to the this digital age. However, for something such as a magazine I still prefer to have a paper copy that I can read while relaxing with a cup of tea or eating my lunch. But, if we only print out articles of particular interest then that certainly saves a lot of paper, and that has to be a worthwhile saving of resources. Bob Flitney
