- The substitution of
fluorine for a hydrogen on a carbon-backbone macromolecule creates a
unique class of rubbers typically referred to as
fluoroelastomers.
- FKM is the
designation for about 80% of fluorinated elastomers as defined in ASTM
D1418.
- Fluorinated
elastomers are perfluoro elastomers (FFKM) and tetrafluoro
ethylene/propylene rubbers (FEPM).
- Fluoroelastomers are
generally made in an emulsion polymerization process.
- Fluoro-monomers such
as HFP, VF2, and TFE are fed to a reactor under elevated temperature and
pressure along with surfactants and other additives.
- Once the
polymerization is complete the latex is removed, the polymer coagulated
and washed, and the polymer is dried and packaged for use.
- Thermal
hydrodehalogenation (THD) is a conversion technique where halons and
CFCs react with hydrogen or hydrogen donor molecules at high temperature
to form a mixture of hydrofluorocarbons (HFCs), hydrocarbons,
perfluorocarbons and mineral acids as products.
- Fluoroelastomers
having higher fluorine content have increasing fluids resistance derived
from increasing fluorine levels.
- Peroxide cured
fluoroelastomers have inherently better water, steam, and acid
resistance.
- Fluoroelastomers are
a high value in use class of synthetic rubber which provide
extraordinary levels of resistance to chemicals, oil and heat, and
service life above 200°C.
- They have limited
resistance to steam, hot water, methanol, and other highly polar fluids.
- They are able to
withstand strong bases and ketones as well as aromatic hydrocarbons,
oils, acids, and steam.
- Fluoropolymers are
designed for high demanding applications in hostile environments. They
represent a high level choice in applications where chemical environment
and high temperatures are the dominating factors.
- Fluorohydrocarbon
elastomers (FKM) are routinely used as sealing devices for gas turbine
engines, auxiliary power units, air cycle machines, filters, integrated
drive generators, hydraulic servos and actuator.
- In recent years, the
new performance needs and the increased demand for high quality
fluoropolymers are requiring the capability of designing and producing
polymer structures using new concepts arising from material sciences and
macromolecular chemistry.
- Demand for high
performance elastomers continues to grow, driven by higher technical,
specification and legislative requirements in the end use sectors such
as automotive, defence and petrochemical industries.
- Western Europe is
the second largest market for fluoroelastomers.
- In Japan, the
production of fluoroelastomers is estimated at 1,300 metric tons. SRI
expects the consumption of fluoro-elastomers in Japan to grow at an
average annual rate of 5 percent.
