Resistance O-Rings (Chemical Processing)
Perfrez 9021C Perfluroelastomer (FFKM)
formulated for Hydrocarbon and Chemical
Sealing components used in equipment found
in chemical and hydrocarbon facilities are
subjected to extremely high temperatures and
aggressive chemical media. Perfrez 9021C is
the product of choice, delivering service to
expectations while competing elastomers
degrade rapidly under similar conditions.
Lower Compression Set, Lower Weight Loss,
Lower Volume Swell
With lower compression set properties and
exceptional thermal and chemical stability
over prolonged service duration, Perfrez
9021C (FFKM) is a black compound that is
properties enhanced for thermal and chemical
stability with exceptional resistance to
aggressive chemical media.
Perfluroelastomers (FFKM) are formulated to
withstand the most corrosive and hostile
service environments where most other
elastomers fail to deliver. Service life of
sealing components is extended significantly
for prolonged operations at upper
temperature limits of 310 degrees C. Organic
and inorganic bases, corrosive acids and
oxidizing agents all subject sealing
components to the upper design limits of
service compatibility. Perfrez 9021C is the
engineer's product of choice as it satisfies
all the requirements for sealing components
used in chemical and hydrocarbon processes.
Weight loss is the result of degradation of
elastomeric sealing products when placed
under extreme service conditions of
temperature and chemical attack. Low weight
loss, lower volume swell and lower
compression set are desirable properties for
sealing components that have to encounter
the service conditions used in equipment for
chemical and hydrocarbon processes. A high
standard of performance specification is
ensured for such applications.
The substitution of atoms of hydrogen with
fluorine, in a process of fluorination,
gives rise to an exceptionally stable
compound because of the stronger bonding
between atoms of carbon and fluorine.
Compounding additives used in the
enhancement of Perfrez 9021C result in its
superior characteristics, enabling
end-products to have extended service life
under harsh operating environments. Perfrez
9021C exhibits reduced weight loss and
degradation when compared with competing
perfluoroelastomer compounds that have been
