Sealing Technology
The use of these seals as an upgrade on installed equipment is expected to provide operators with the benefit of reduced life cycle costs. Upgrades will be available to centrifugal compressor operators in the fourth quarter of 2008, and for steam turbines in the second half of 2009. “These seals can substantially reduce internal leakage and improve overall efficiency for any rotating equipment,” said H. Allan Kidd, director of Emerging Technologies at Dresser-Rand. “By reducing leakage within a machine, operating costs are reduced because overall energy consumption is less.” CMG Tech is an energy technology consulting service located in Rexford, New York, USA.

New FFKM offers low set at high temperature
G
reene, Tweed has introduced a new perfluoroelastomer, Chemraz XCD, designed to offer high temperature performance with low compression set for semi-conductor applications. The new material is recommended for service temperatures up to 300ºC at which the lower compression set coupled with higher thermal stability helps the material maintain its elasticity and sealing force. It also demonstrates low out-gassing characteristics and reduced sticking force which helps prevent seals from tearing in semi-dynamic applications. The material is the result of a collaborative effort between Greene, Tweed and Daikin Industries, Ltd. It is intended to extend the range of materials into the high-purity, thermal-processing segment of the semiconductor processing industry such as Low Pressure Chemical Vapour Deposition (LPCVD) and Rapid Thermal Processing (RTP).

New HNBR latex for improved heat and oil resistance
Z
eon Chemicals’ has extended the range of the Chemisat product line with the introduction of Chemisat LCH 7272 a new hydrogenated NBR in latex form that offers advanced adhesive properties, with resistance to heat, fluid, ozone, UV, oxygen and abrasion. LCH 7272 provides improved heat aging compared to conventional NBR lattices. The production of Chemisat involves hydrogenation of latex without an intervening conversion to a dry HNBR, unlike conventional HNBR processes, and no solvents are required. It is intended for applications such as belts and hoses with fabric reinforcement. Reinforcing these fabrics by pre-coating with Chemisat and moulding with Zetpol creates products with improved strength and longterm aging properties.

New brochure to assist designers
A
brochure has been introduced by Interface Solutions (ISI) to assist OEM design engineers during the product design and development stages. Aimed at design engineers who develop sealing solutions for engines, transmissions and other original equipment applications ‘Engineering Technically Reliable, CostEffective Sealing Solutions’ describes the systems approach used by ISI to support OEM design engineers during the product design and development stages. Separate brochure sections cover each design step process, beginning with material selection and culminating in design verification and production approval.
