Trelleborg expands with acquisition and new plantSwedish-based Trelleborg hasacquired Norwegian companyMehren Rubber A/S, and has alsocompleted a new plant in China.
The purchase of Mehren Rubber,to join the Engineered Systems busi-ness of Trelleborg, is part of the com-pany policy to expand in the offshorebusiness. Mehren is a niche-orientedcontract producer of down-holepackers for Easywell, a subsidiary ofHalliburton. Its main product isSwell Packer, a down-hole packerdesigned to swell when in position.
The company has also inaugurat-ed a newly constructed manufactur-ing facility for Sealing Solutions inthe Shanghai region. The increasedproduction capacity from this newplant means that Trelleborg is nowbetter able to meet increasingdemand from industry in China andthe rest of Asia.
‘We are committed to expandingaggressively in Asia,’ says TrelleborgPresident and CEO, Peter Nilsson.‘This facility continues our strategicinvestments in the region, and it willbe followed by others, in China andin other Asian countries.’
It will have about 100 employeesby the end of the year and the plant,which is designed to meet stringentenvironmental standards, will havetotal floor space of 10 000 m2. It willproduce many proprietary productsfor the aerospace, chemical process-ing, semiconductors, and oil and gasindustries, and also provide technicalsupport, design, product develop-ment and testing facilities.

Training CD extended to include failuresThe CD produced by the VDMAin Germany as a training tool onfluid power seals has been extend-ed to include a failure mode atlas.
This training material, preparedby the fluid power sealing manufac-turers of the VDMA, has been avail-able for a number of years, and pro-vides a well illustrated introductionto fluid power seals. The latest ver-sion now includes an extensive fail-ure guide. The format is a series ofvery clear diagrams in a PowerPointpresentation with a brief explana-tion and potential solutions. Thediagrams are particularly useful inillustrating problem areas. Itincludes sections on static, recipro-cating and rotary seals. The text is
provided in both English andGerman.
In order to promote an apprecia-tion of the importance of sealingtechnology, this CD is provided freeto engineering students. It is alsoavailable to other interested partiesfor �49 + VAT. It can be orderedfrom Ralf Stemmjack at the VDMAby quoting the code: VDMA CD-ROM Sealing Systems, and provid-ing full contact and address detailsby fax or email to the contact below.

Adhesion to fluoropolymers isreviewedAdhesion to fluoropolymers isthe title of a new book availablefrom Rapra Technology.
Written by Dr Derek Brewis andDr Ralf Dahm, it covers the princi-ples of adhesion and techniquesthat have increased the under-standing of the subject. However,as pre-treatments are usually need-ed to get the required level of adhe-sion, the review is mainly con-cerned with the wide variety ofmethods available to pre-treat fluo-
ropolymers, together with a gener-al discussion and conclusions.Cases where good adhesion isachieved without a pre-treatmentare also examined. Price is £85 pluspostage and packaging.

Trelleborg Sealing Solutions Shanghai – the increased productioncapacity from this new plant means that Trelleborg AB is now betterable to meet increasing demand from industry in China and the rest of Asia.
Vespel production is increasedDuPont Engineering Polymershas expanded polyimide resinproduction to provide a 50%increase in the resin requiredfor production of direct-formedVespel SP-1 and SP-21 poly-imide parts.
The newly commissioned unit,located in Circleville, Ohio, isdedicated to the production ofpolyimide resin for direct-formedVespel S parts made at otherDuPont sites. Production of
SP-21 has already started, andproduction of SP-1 will com-mence shortly.
