FLUORO TECHNOLOGIES CREATED NEW DIMENSIONS FOR LIQUID SILICONE RUBBER Unique Materials Unite the Best of FSR and Best of LSR

摘要

Fluorosilicones (FVMQs) are very competitive when used in applications requiring wide operating temperatures and fluid resistance. Their unique physical properties have never been in greater demand for applications in contact with jet/automotive fuels, solvents and/or engine oils. As more fabricators manufacture products using fluorosilicones and competition increases, Dow Coming's high consistency fluorosilicone compound technology (FSR) has evolved to offer greater flexibility in meeting these requirements. At the same time, Dow Corning understood there were still unmet needs for fluorinated materials for use in liquid injection molding equipment. Dimethyl based liquid silicone rubber (LSR) was initially developed to allow manufacturers to produce rubber parts more efficiently by providing fast cycle times, less contamination (closed system), material waste reduction, and automated processing. However, automotive parts fabricators and OEMs could not guarantee long term performance of LSR molded parts in certain environments due to insufficient resistance to fuel or other aggressive fluids. To take advantage of the strengths of both technologies, Dow Corning has developed a new product range containing copolymer and fully fluorinated LSR that allows the process efficiencies of LSR to be integrated with the performance capabilities of FSR. Dow Corning has also expanded its product offering self-bleed versions. This paper will highlight the innovative possibilities and benefits of the new Silastic~R brand F-LSR product series.
