Fluororubber (FKM/FPM) is a high-performance elastomer polymerized from fluorinated monomers. Thanks to its strong carbon-fluorine (C-F) bonds, FKM delivers outstanding high-temperature, oil, and chemical resistance, making it the material of choice for demanding seals in automotive, aerospace, petrochemical, and semiconductor industries. This guide explains what fluororubber is, analyzes its key properties (temperature range, chemical resistance, mechanical performance) and main applications, and provides a selection guide with common grades. As a specialized FKM supplier, huagong offers multiple raw rubber and compound grades — contact us for quotes.
