Aflas 300S O rings seals
AFLAS 300S Latex is an alternating tetrafluoroethylene–propylene copolymer with a cure site
monomer in an aqueous suspension. It is used as an elastomeric surface treatment of various
substrates such as metals, ceramics, plastics, other elastomers, textiles, and paper. The
incorporated cure site monomer allows this material to be cured using either peroxide systems or
electron beam irradiation. Classified by ASTM D 1418-01 as FEPM.
Heat Resistance*: Mechanical properties of AFLAS do not deteriorate even when used for
prolonged exposure to 200°C. AFLAS can be used continuously for 2 to 3 months at 230°C and
for 10-30 days at 260°C.
Chemical Resistance: Parts fabricated from AFLAS compounds perform well in the amine and
base-rich environments commonly found in sour oil and gas exploration, completion and
production. In automotive and heavy equipment applications, AFLAS stands up well to attack from
amine-containing additives in oils and transmission fluids.
Steam Resistance*: Unaffected by extended exposure to 200°C steam.
Electrical Properties: Excellent volume resistivity (greater than 1016 Ω-cm) unmatched by other
Radiation Resistance*: Stable up to 2000 kGy of gamma ray radiation.
*Application design may vary results.
END USER BENEFITS
Excellent thermal and chemical stability
Surface modified parts
AFLAS 300S Latex contains residual amounts of materials used in polymerization including tertiary
butyl alcohol. Use in well ventilated work areas.
AFLAS 300S Latex can be diluted with water; however, the user should test the stability (suspension,
etc.) of the diluted latex prior to use.
Other additives can be added to the latex; again, the user should test the stability (suspension, etc.) of
the latex prior to use.
Treat hydrophobic substrate surfaces with primers, coupling agents, or other agents prior to
application of the latex.
AFLAS 300S Latex may become coagulated by impact or by exposure to freezing temperatures.
To prevent contamination, do not mix used AFLAS 300S Latex with fresh latex.
