Tecnoflon® PFR LT represents a breakthrough in perfluoroelastomer (FFKM) technology. It offers outstanding sealing behaviour in the widest range of aggressive media along with excellent compression set values and best in class low temperature flexibility. Thanks to a new proprietary fluorinated monomer technology, Tecnoflon® PFR LT extends the low temperature sealing capability of perfluoroelastomers down to –40°C (from approximately –10°C), whilst retaining typical fluid resistance. 
It is suitable for most applications in temperature ranging from –40°C to 230°C, offering outstanding resistance to aggressive media such as hot organic and inorganic acids, caustics, amines (especially hot amines, i.e. at temperature higher than +70°C), ketones, aldehydes, esters, ethers, alcohols, fuels, solvents, sour gases, hydrocarbons, steam, hot water, formate solutions and mixed process streams. 
Tecnoflon® PFR LT can be combined with the cure system and other typical fluoroelastomer compounding ingredients; its mixing can be accomplished with two roll mills or internal mixers. Finished goods may be produced by a variety of rubber processing methods. 
The primary use for Tecnoflon® PFR LT is the manufacturing of any kind of elastomeric sealing element such as Orings, gaskets, valve bodies, butterfly valves, pump housings and stators, metal bonded parts, diaphragms, profiles, etc. These sealing elements can be used in mechanical seals, pumps, compressors, valves, reactors, mixers, sprayers, dispensers, quick connect couplings, controls, instrumentation, etc. in a wide range of industrial sectors. 
Tecnoflon® PFR LT is marketed in the form of raw polymer (1kg box) in order to give the transformer the freedom and the opportunity to develop and fine tune compounds and items best suited to the final application.
