F-LSRs provide processing efficiency for fuel-resistant automotive parts
D
ow Corning Corp, which specialises in silicone and silicon-based technology, says that building on its elastomer technology in fluoro liquid silicone rubber (F-LSR) has enabled it to introduce two new Silastic brand products to expand design options and provide processing efficiency for fuelresistant automotive components. The latest products add 60 and 70 durometer hardness options to a growing family of fully and partially fluorinated liquid silicone rubbers. Amongst the latest products to be released recently by the company are Silastic FL 60-9201 (60 Shore A durometer) and Silastic FL 70-9201 F-LSR (70 Shore A durometer). According to the firm, both exhibit excellent resistance to non-polar hydrocarbon fuels, oils and solvents and offer process cost-savings, especially for moulding small parts in high volumes. Silastic FL 60-9201 F-LSR provides excellent flexibility for dynamic seals such as diaphragms and membranes, whilst Silastic FL 70-9201 F-LSR provides high modulus, with low compression set, for static seals such as O-rings and gaskets. ‘These Silastic F-LSR products give designers added flexibility for meeting critical performance requirements on small, intricate high-precision or over-moulded parts that must withstand harsh service conditions,’ said Gabe Knee, Automotive Market Leader, Dow Corning. ‘And, the Silastic F-LSR technology offers fabricators substantial process gains for producing newer seals, gaskets, connectors, flexible diaphragms, membranes and valves using standard injection-moulding equipment.’

Clutch piston technology aims to make vehicles more fuel-efficient

IN BRIEF

Mogul Holdings Corp, has developed clutch piston technology which, it claims, will enable vehicles with automatic or dual-clutch transmissions to become more fuel-efficient. The company says that its new high-modulus Unipiston gives transmission designers more flexibility, including increased clutch-apply pressures, higher rotational clutch speeds and larger diameter clutches. This flexibility enables transmissions with additional clutches to be packaged in a smaller space, whilst providing improved fuel economy, reduced emissions and enhanced vehicle performance. To produce a high-modulus (stiffness) bonded piston using environment-friendly materials, the company says that it developed a new elastomer material and introduced a number of innovations to the moulding process. ‘Federal-Mogul Powertrain now has the unique ability to manufacture bonded clutch pistons using a high-modulus, environmentally-safe material,’ explained Mike Gerulski, Director, Advanced Technology, Federal-Mogul Powertrain Sealing and Gaskets. ‘The breakthrough enables us to offer bonded clutch pistons designed with an elastomeric material possessing a modulus approximately twice as high as production bonded pistons on the market today – resulting in at least twice the life in high-pressure cyclic bench-testing than current production products.’ According to Federal-Mogul, conventional bonded piston seal materials manufactured using traditional injection-moulding techniques are limited in their modulus to around 10 MPa, since elastomer viscosity increases with modulus – resulting in challenges when filling the mould cavity. It says its combined development of the new elastomer material and manufacturing process results in a Unipiston with a modulus of over 20 MPa, which cannot be attained using traditional injection-moulding processes. ‘The introduction of the original bonded clutch pistons by Federal-Mogul almost 30 years ago helped make clutch pistons more compact and easier to assemble,’ said Gian Maria Olivetti, CEO, Federal-Mogul Powertrain.
Victaulic Vic-Press system receives new type approvals Manufacturer of mechanical pipe-joining systems Victaulic Co has received type approvals from the American Bureau of Shipping (ABS), Bureau Veritas (BV), Det Norske Veritas (DNV), Korean Register and Lloyd’s Register for Vic-Press, a flame-free press system for joining small-diameter stainless steel piping. With these new approvals, more shipbuilders will be able to take advantage of Vic-Press as a quick, simple, safe and reliable means of joining stainless steel pipes when constructing new vessels, and during retrofit and repair operations, says the company. The system is approved for use in class III piping systems for marine and offshore applications. Quadrant EPP appoints global business line manager Manufacturer of high-performance thermoplastic materials Quadrant Engineering Plastic Products (EPP) has announced that Terry Folk has been promoted to Global Business Line Manager – Cast & Custom Cast Products, and will be based at the company’s US headquarters in Reading, Pennsylvania. A 34-year veteran of Quadrant EPP, Folk has maintained key roles at the firm’s US headquarters – most recently as the supply chain manager of the American markets. In his new position he will remain an executive member of the Americas regional leadership team and share responsibility for profit and loss with the regional presidents. Dow achieves sustainability milestone Betamate structural adhesives have been named Dow Chemical Co’s third ‘Breakthrough to World Challenges’ – meeting a milestone set by the firm as part of its 2015 sustainability goals. A recent recipient of a 2014 R & D 100 Award and two 2014 PACE Awards, Betamate is used to bond the body structure of cars during assembly which, says Dow, enables improved vehicle safety and durability whilst optimising weight reduction and providing greater design flexibility. Ashton Seals appoints two new directors Ashton Seals Ltd, a UK-based supplier of O-rings, bonded seals and associated sealing products, has appointed two new directors. Matthew Wood, previously Technical & Quality Manager, has been promoted to Technical Director, whilst Marketing Manager John Greathead becomes Marketing Director. Tim Wills, Managing Director, Ashton Seals, commented: ‘It gives me great delight to be able to offer directorships to two people who for years have exhibited the necessary qualities to become a director of Ashtons. Matthew and John greatly deserve their promotions and I warmly congratulate them.’
