Fluorosilicone elastomer. (Materials).

FSL7586/40 liquid self-lubricating fluorosilicone elastomer is used in automotive gasketing and sealing materials applications. Designed for use in gasketing and sealing applications both under-hood and on the automotive powertrain, FSL7586/40 elastomer is said to provide improved resistance to both lubricants and fuels, and it is said to be characterized by a low compression set without the need for post-cure operations. FSL7586/40 self-lubricating fluorosilicone elastomer is said to provide reduced insertion force for either manual or automated manufacturing processes. High curing speed and easy de-molding are said to permit fully automated production of large numbers of articles in short cycle times, according to the company. FSL7586/40 elastomer is designed for use in applications such as fuel seals, o-rings, connector grommets and seals, and throttle valve gaskets. FSL7586/40 is a two-component fluorosilicone elastomer that, when blended together, is said to achieve the following key performance properties: 40 durometer A hardness, tensile strength of 725 psi, tear strength of 114 ppi and compression set of 17 (22 hrs./175[degrees]C). FSL7586/40 elastomer is said to offer balanced fluid- and solvent-resistant properties with demonstrated resistance to ASTM Oil No. 1, IRM903, Test Fuel C, Aral Diesel, RME and various other motor oils.
