Fluoroelastomer Is a Type of Fluoropolymer Rubber and Is Used For Making Seals and Barrier Layers5/3/2023 A fluoroelastomer is a polymeric rubber-like material with high thermal stability, nonflammability, and resistance to many corrosive media. They are used for hoses, diaphragms, accumulator bladders, gaskets, O-rings, and seals that operate in harsh environments. They are mainly used in the chemical, automotive, aerospace, and energy industries. Their superior chemical resistance and heat stability are expected to drive their market growth over the forecast period.
Fluor elastomer hoses, seals, and gaskets are widely used in the oil and gas industry due to their temperature and chemical resistance. They can be used in a wide range of applications including fuel systems, diaphragms, elastic connections, and valve stem seals. Typical operating temperatures for Fluoroelastomers are from -40 to +400 deg F (-40 to 205 deg C). This allows the hoses, seals, and gaskets to withstand the harsh environmental conditions associated with high-temperature processes in the oil and gas industry. A variety of different fluoroe lastomers have been developed to provide the best performance for each application and service condition. For example, Viton(TM) fluoroe lastomers are known for their superior heat and chemical resistance in a wide range of industrial processes. Fluoroelastomers have excellent chemical resistance, which makes them ideal for use with a wide variety of chemicals. These materials are used in a wide range of environments including the oil and gas industry, automotive industries, and food processing. There are several factors that affect the chemical resistance of a polymer. These include molecular structure, mechanical load, additives, reagent concentration, temperature, exposure duration, and chemical combination. The chemical resistance of a polymer also depends on the final product. For instance, if a rubber material is not compatible with the chemicals it is used with, the rubber could deteriorate or degrade rapidly. Dupont offers a number of peroxide-cured fluoroe lastomers that offer superior chemical resistance. These include Viton ETP(r), a tetrafluoroethylene (TFE) and perfluoro methyl vinyl ether (PMVE) based polymer that provides high resistance to fuels, solvents, acids, bases, and amines. This polymer can be cured with bisphenols or peroxides, which reduces curing time and cost. Fluoroelastomers are fluorinated synthetic polymers designed to withstand harsh environments including aggressive chemical and temperature applications. They have good compression, sunlight & ozone resistance, and a low gas absorption rate. The gas permeability of a material is a measure of the rate at which a given volume of gas permeates through the unit area of the material under constant pressure and temperature. It is measured using a variety of methods and commercially available test cells. A comparison of the gas permeances of composite membranes with those of thick films shows that direct fluorination results in a decrease in hydrogen and methane gas permeances by a factor of 2-3 for PMP and PSF (Figure 3). However, the effects of surface fluorination on effective permeability coefficients are much less. A major challenge for the development of fluoroe lastomers is to make them perform well in harsh environmental conditions and for specific applications. This requires innovative technologies and new fluorochemical compounds that can withstand extreme temperatures and chemicals.
