Aflas 300S O rings seals

DESCRIPTION

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.

MATERIAL FEATURES

? 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 ?-cm) unmatched by other

fluoroelastomers.

? Radiation Resistance*: Stable up to 2000 kGy of gamma ray radiation.

*Application design may vary results.

END USER BENEFITS

? Improved flexibility

? Excellent thermal and chemical stability

TYPICAL APPLICATIONS

? Coating additives

? Surface modified parts

? And more…

PROCESSING RECOMMENDATIONS

? 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.
