DESCRIPTION
Tecnoflon FKM fluoroelastomers consist of copolymers and
terpolymers with a fluorine content of 66% and 68-70% respectively.
They are available as base polymers (gumstock) or products
formulated with ionic or peroxide curable systems.
Ionic Curable FKM
Ionic curable FKM materials have a good balance of mechanical
properties and sealing performance along with ease of processing.
They are available as base polymers (gumstock) or grades formulated
with incorporated cure systems (denoted by the FOR prefix in the
grade name). A variety of possible combinations of viscosity, cure
rate, and cross-link density make them suitable for any molding
process. The HS copolymers are designed for low post-cure cycles.
Rubber-to-metal bonding grades are available for all molding
techniques.
Ionic curable Tecnoflon® FKM products are categorized according to
their monomer composition
* Copolymers are versatile polymers based on VDF and HFP monomers
and have a fluorine content of 66%.
* Terpolymers offer better chemical resistance than copolymers due
to their higher fluorine content (68-70%).
* Low-temperature terpolymers provide chemical resistance similar
to ionic curable copolymers. Polymers have a fluorine content of
65.5% and they exhibit a lower glass transition temperature (Tg).
FKM Tecnoflon PFR 06HC is a new chemical resistant perfluoroelastomer (FFKM). Tecnoflon®
PFR 06HC offers the widest range of aggressive media sealing
capabilities along with excellent compression set values.
It is suitable for most applications in temperature ranging from
-10°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, ethylene and propylene oxide
and mixed process streams. Moreover it can cope with a wide range
of potent active pharmaceutical ingredients (APIs) and aggressive
cleaning agents, being especially suited to withstand
steam-in-place (SIP) and clean-in-place (CIP) procedures.
Moreover its structure was specifically designed to deliver
enhanced extrusion resistance and rapid gas decompression (RGD or
explosive decompression ED) resistance requested for many high
pressure gas applications in the oil & gas industry.
Its extreme cleanliness along with its broad chemical resistance
make PFR 06HC the suitable sealing material for most wet
semiconductor processes (wafer cleaning, polymer removal, wet
etching, polishing), for photolithography developing and stripping
and for general purpose fab equipments (pumps, scrubbers, filters,
chemicals delivery systems).
PFR 06HC 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 PFR 06HC is the manufacturing of any kind of
elastomeric sealing element such as O-rings, 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 06HC is
marketed in the form of raw polymer (1 kg 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.
