Tecnoflon® PFR X1055B is a new perfluoroelastomer (FFKM) offering outstanding thermal resistance, lower compression set and enhanced sealing-force retention at extreme temperatures. Tecnoflon® PFR X1055B is suitable for most applications at temperatures ranging from –10 to 315°C.
Along with excellent thermal resistance, it can offer broad chemical resistance in a wide variety of media, including acids, caustics, ketones, aldehydes, esters, ethers, alcohols, solvents, sour gases and hydrocarbons. However, it is not recommended for use in severe aqueous and amine applications.  
This unique combination of thermal and chemical resistance makes Tecnoflon® PFR X1055B the sealing material of choice for high temperature chemical and hydrocarbon processing industries as well as aerospace applications. 
At the same time its extreme cleanliness (low metal ion content with low extractables), along with its superior thermal stability and its plasma resistance, make Tecnoflon® PFR X1055B a very suitable sealing material for most dry plasma (etching, PECVD, LPCVD, metal CVD, PVD, ALD, plasma cleans) and high temperature thermal processes in the semiconductor manufacturing industry.
Tecnoflon® PFR X1055B can be combined with other typical fluoroelastomer compounding ingredients; it can be mixed either by using two-roll mills or internal mixers. Finished goods may be produced by a variety of rubber-processing methods. 
The primary use of Tecnoflon® PFR X1055B is manufacture of any kind of elastomeric sealing element such as O-rings, gaskets, flanges, 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 the chemical and petrochemical industry as well as the hydrocarbon processing, aerospace and semiconductor manufacturing industries.  
Tecnoflon® PFR X1055B is marketed in raw polymer form (1 kg box) in order to give the transformer the freedom and the opportunity to develop and fine-tune compounds as well as items best-suited to producing high performance rubber articles.
