The polysiloxane-backbone can contain methyl-, vinyl- and flourine-functionalised side chains.<\/p>\n<p>Fluorosilicones combine the high- and low-temperature properties of silicones with the resistance to oils and fuels of fluoropolymers. The fluorosilicones offer a larger service temperature range as the fluorocarbon elastomers (FKM\u2019s). O-rings made of fluorosilicone are mainly used in high temperature fuel-systems in which silicone has to be resistant to dry heat. O-rings made of fluorosilicone can also be exposed to petroleum-based oils and\/or hydrocarbon-containing fuels. By the utilisation of some oils and fuels it is recommended to reduce the maximum service temperature, because the decomposizion of the fluorosilcones, starting at 200\u00b0C, liberates acids which can attack on their part the material. In low-temperature domains the fluorosilicone o-rings can be used till \u201373\u00b0C. Due to the slight tensile-strength, the high friction coefficient and the unsatisfactory wastage properties, fluorosilicone o-rings are recommended in general only for static applications, however fluorosilicones with high tensile strength are also obtainable. Some of these compounds show an improved compression set rest. Many fluorosilicone-compounds possess an outstanding high shrinkage-rate. Due to the diversity of the fluorosilicones the fabrication-forms of the fluorsilicones differ from that of other fluorocarbon elastomers. <\/p>\n<h2>Usage:<\/h2>\n<ul>\n<li>aeronautical application<\/li>\n<li>high temperature resistant coolant tubes for trucks<\/li>\n<li>membranes<\/li>\n<li>sealings<\/li>\n<li>application involving resistance to fuels, oils and solvents<\/li>\n<\/ul>\n<h2>Formula:<\/h2>\n<p><img fetchpriority=\"high\" decoding=\"async\" src=\"\/wp-content\/uploads\/FVMQ.jpg\" alt=\"Fluoro-Silicone-Rubbers (MFQ or FVMQ)\" width=\"400\" height=\"303\"><\/p>\n<blockquote><p>Category:<br \/>Elastomer<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Description: Nomenclature: MFQ according to ISO 1629 (&#8220;Rubber and latices \u2013 Nomenclature&#8221;) or FVMQ according to ASTM 1418 (&#8220;Practice for Rubber and Rubber Latices \u2014 Nomenclature&#8221;); high temperature resistant up to +200\u00b0C and more, less resistant to chemical compunds and solvents than FPM, flexible at low temperatures.
