Self-lubricating seal is designed for press tap
NEWS no contaminants go into the clean-room production of semiconductor wafers and chips – VO628 and VO793 can be used in a variety of products, including O-rings and bonded gates. VO628 and VO793 have a 65 Shore A and 75 Shore A hardness, respectively. They are brown in colour and both materials contain no fillers and minimal metal-ion impurities, so that they offer superior, high-temperature and longterm compression set characteristics, compared with traditional FKM materials. Capable of resisting oxygen etch and oxygen plasma processes and performing well in rapid pump-down high-vacuum systems, VO628 and VO793 are useful in semiconductor applications that require a rapid development of high vacuum levels.

Self-lubricating seal is designed for press tap
D
P Seals Ltd has developed a selflubricating seal for Eurotaps’ Pressatap timed-delay tap inserts. A fluorinated additive contained in the custom EPDM moulding helps to ensure that the tap insert works over a long period. Eurotaps is offering a range of inserts for use in taps in public places. They can be retrofitted to most taps and have been developed to significantly reduce water wastage. The three insert types include straight on/off, timed delay and a special timed delay that only releases water once the tap is depressed and released, making it ideal for use in schools. The rubber seal is fundamental to the efficient and effective long-term operation of the unit. Eurotaps machined these seals from solid EPDM rod but it experienced variable performance because of inconsistencies within the rod material and insufficient tolerance control. The company approached DP Seals which developed a tool for the seal, eliminating the tolerance problems, and created a special blend of EPDM. This material incorporates a new fluorinated polymer additive that lowers the coefficient of friction by controlled migration to the moulding surface, reducing squeaking and improving sliding characteristics over a metal surface. Interestingly, when blended with EPDM, the additive also improves water repellency – which is beneficial in this application. 4
Sealing Technology
Company News Partnership set to develop PEEK products enhanced by carbon nanotubes olvay Advanced Polymers Llc has formed a partnership with Entegris Inc’s TEGO Polymers unit to develop and market advanced PEEK products, enhanced by carbon nanotubes, for emerging applications in the medical, aerospace, automotive, and oil and gas industries. Solvay will supply its KetaSpire PEEK resin to Entegris which, in turn, will sell compounds using its novel, carbon nanotube technology (CNT). These compounds are targeted at applications that require materials with reduced weight, enhanced stiffness and flexibility, and possess good thermal management and static charge dissipation. ‘We are excited about this opportunity to support Entegris’ TEGO Polymers and its new range of compounds based on KetaSpire PEEK,’ commented Greg Jack, a senior business development representative for Solvay Advanced Polymers. ‘This partnership will spur greater use of our materials and open up new end-use applications where consistent electrostatic discharge properties and improved thermal stability are required.’ Entegris has developed proprietary technology for the uniform dispersion of carbon nanotubes in PEEK and other thermoplastics, to create homogeneous blends. Unlike other filler materials, such as carbon fibre and carbon powder, carbon nanotubes preserve and maintain the properties of the base polymer. These specialised formulations blend singlewalled or multi-walled carbon nanotubes with a polymer. The CNT materials have a high strength while preserving flexibility, and uniform electrical and thermal conductivity.

ElringKlinger set to buy Freudenberg gasket business
I
n Germany, ElringKlinger AG of Dettingen an der Erms is planning to acquire the cylinder-head and exhaustsystem gasket business of Freudenberg & Co Kg, based in Weinheim Contractual negotiations have reached an advanced stage, say the companies. Freudenberg’s business produces the seals in three countries in Europe – in Eurasburg and Geretsried-Gelting, Germany; Chamboret and Nantiat in France; and Settimo in Italy. Freudenberg is methodically working on the strategic alignment of its product portfolio. The company says that as it is focusing its sealing technology activities on its globally-oriented core business, the Europe-biased cylinder-head and exhaust-gasket business is to be disinvested. As a result, it will no longer be active as an OEM for the automotive industry in this sector. This acquisition will help ElringKlinger strengthen its position worldwide within the field of cylinder-head gaskets and high-performance speciality gaskets for engines and exhaust systems. The acquisition of the static metal gasket business from the Freudenberg Group will enable it to cement its position within the market for flat gaskets. In the area of speciality gaskets, the company will have the opportunity to extend its portfolio by adding new products and applications in, for example, the rapidly growing segment of turbochargers and exhaust recirculation, as well as capturing additional market share from vehicle manufacturers in France and Germany as well as in Italy. ElringKlinger anticipates a more pronounced rate of consolidation within the automotive supply market which – beyond organic growth, generated through new products – will offer the company good opportunities for targeted technology-driven acquisitions as well as the expansion of market share in existing fields of business.
