Fluoroelastomers and Perfluoroelastomers
Tecnoflon® FKM and PFR FFKM (fluoroelastomers and perfluoroelastomers) are designed for demanding sealing applications in aggressive chemical and high heat environments such as those found in the Automotive, Aerospace, Oil & Gas, and Energy markets and where high purity, and long service life are essential.
They are compatible with a wide range of fluids and chemicals including automotive lubricants, fuels, and additives. Typical end use products include O-rings, seals, gaskets, and complex molded parts.
Tecnoflon® PFR FFKM perfluoroelastomers show the ultimate performance among all elastomers. They are resistant to nearly every chemical class with some grades offering heat resistance over 300°C, making Tecnoflon® PFR the material of choice for high demanding sealing applications. Market specific grades have been specially developed to answer the stringent requirements of the semiconductor, oil & gas and chemical processing industries.
Tecnoflon® FKM Base Resistant grades are a special class of peroxide curable grades, designed with improved chemical resistance in Oil & Gas applications with high sour gas concentration, steam, lubricants with amine-based anti-corrosion additives and the latest aggressive automotive gear and axle lubricants.
Tecnoflon® FKM Ionic Curable grades are copolymers and terpolymers with a fluorine content range from 66% to 70% and are well suited for automotive, industrial and aerospace applications. The HS copolymers are designed for low post-cure cycles and cure-incorporated and rubber-to-metal bonding grades are available for all molding techniques.
Tecnoflon® FKM Peroxide Curable grades are the best-in-class chemical resistance grades with a fluorine content range from 67% to 70%. They are designed to produce O-rings, shaft-seals, turbo charger hoses and complex shapes for the automotive and chemical process industry. The peroxide curable grades show excellent processability by injection or compression molding.
Tecnoflon® FKM Low Temperature grades are a wide portfolio including ionic and peroxide curable grades with TR10 range from -19°C to -40°C. They are specially designed for sealing solutions in oil drilling in cold environment as well as in the latest automotive engine technologies, like LPG, CNG and high-performance fuel injection systems.
The VPL Peroxide Curable grades are able to withstand the most stringent specifications for automotive and oil field applications, with TR10 down to -40°C and superior chemical resistance compared to standard low temperature FKM.
