Materials are aimed at the aerospace market Busak+Shamban has introduced two new materials specifically for the aerospace business. Turcon M30 is a PTFE-based non-abrasive material for high-pressure applications, developed to offer reliable sealing for the increased component life expected of flight controls on the new generation of civil aircraft such as the Airbus A380 and the Boeing B787. Designed as an optimum compound crystalline form to give the material a dense and homogeneous structure, it contains aromatic polymer fillers for high temperature resistance. The use of non-abrasive filler materials stops abrasion of mating surfaces under high loading conditions. The Turel LTFE range of fluorocarbon elastomer (FKM) based materials can operate as low as –40°C and also up to 200°C. Immersion testing shows good resistance to a wide range of aircraft fluids, including acceptable resistance to Skydrol 500B.

In addition, the company is also emphasizing the innovative technology used to manufacture inflatable cockpit seals for aircraft. These are considered high-tech products, yet are still hand-fabricated in tools the full size and shape of the jet fighter cockpit. The inflatable seals are built up layer by layer, cured within the tool, then tested at line-side. The cockpit seal is fitted to the edge of the canopy. When the canopy is closed the seal is inflated, filling the gap between the plane’s cockpit and its canopy. They can see service at a ceiling of up to 15 000 m altitude, maximum speed of 2000 km/h and rates of climb of 12 000 m/min.

New thermoplastic elastomers have lower viscosity Solvay Engineered Polymers has introduced a new series of vulcanized thermoplastic elastomers (TPVs). These materials in the NexPrene 9500 Super High Flow (SHF) series are particularly stable, and they can be processed at higher temperatures than standard TPVs. The viscosity is 60% less than standard materials. One application for which the new series was developed is the encapsulation of window glass, which involves a temperature range between 190°C and 245°C. Lower molding pressures avoid glass breakage. At such

temperatures, the new materials exhibit viscosities that remain 40–60% below those of traditional TPVs, which can contribute to lower scrap rates and lower costs. The polymers can also be molded at higher temperatures, which helps to improve bonding to other materials. Contact: Solvay Advanced Polymers, 100 South Mitchell Road, Mansfield, TX 76063, USA.

New hot-melt sealant offers longer working time, and more flexibility Dow Corning has introduced a new hot melt sealant that combines the instant green strength of a pressure-sensitive adhesive (PSA) with the high performance of a cross-linked silicone sealant. The benefits of this material can include improved productivity, increased production speed and reduced costs. HM-2510 was developed to have a lower viscosity than the current HM-2500 Assembly Sealant. This allows it to flow into deeper sections and

achieve a longer working time by combining the production benefits of instant adhesion with the reliability of silicone sealants. Instant green strength also means that parts can be moved immediately from one processing step to the next. Contact: Dow Corning GmbH, Postfach 130332, D-65091 Wiesbaden, Germany.

Simrit expands oil and gas business The manufacture of an inflatable cockpit seal at Trelleborg Sealing Solutions involves hand fabrication of a complex geometry multilayer hollow molding.

MoD contract for naval O-rings Precision Polymer Engineering has been awarded a three-year sole-supplier contract by the UK Ministry of Defence, for DefStan 02-337 (NES 337) specification O-rings. The seals, which may be nitrile or fluorocarbon, are specified for applications in hydraulic, lubrication, fuel and pneumatic systems on Navy surface ships and submarines.

Freudenberg-NOK has acquired the assets of Imperial Rubber and Urethane Corporation of Nisku, Alberta, Canada. The company will continue to manufacture oil and gas products at its two current facilities located in Nisku, Alberta and will be part of the Simrit industrial sealing products division. ‘I am thrilled that Imperial Rubber is joining Simrit, as it is a perfect match for our strategy to grow our capability to serve the oil and gas segment,’ says David Monaco, president of Simrit. ‘Through this partnership, Imperial Rubber’s standards of quick response time, depth of

market knowledge, strong customer relationships and competitive pricing will be supplemented by Simrit’s global presence, material expertise and elastomer processing knowledge.’ According to Monaco, there will be no change in sales or customer service. Through the acquisition the company will gain product expertise plus a wide range of oil industry product lines. Contact: Freudenberg-NOK GP, 47690 East Anchor Court, Plymouth, MI 48170-2455, USA.
