Aflas Chemical

A copolymer of
tetrafluoroethylene and properly, AFLAS exhibition excellent chemical
resistance properties, and good to fair high temperature retention of
physical properties.Key use: Seals for Oil field, industries and chemical applications.Working Temperature Range: - 23 oF to + 400 oF. (Dry Heat Only).Features:
With good resistance to petroleum fluids; steam; a number of acid and
alkalizes; amines (anti-freeze); phosphate esters and brake fluids,
AFLAS has generated considerable interest as a seal material for oil
field, industrial and chemical applications.Laboratory
tests have demonstrated a high degree of heat resistance (to 400 oF)
with retention of slightly below average (2,500 psi) tensile
properties. Tests have further shown abrasion resistance to be about
the same as fluorocarbon; cracking to appear after 100 to 200 flexes at
400 oF; and no change in material properties after one year of
weathering.Limitations: Seven day
immersion, at room temperature, in solvents indicates such significant
volume change as 50% in Acetone; 58% in MEK; 95% in MIK; 112% in methyl
chloroform; and 249% in Trichlorotrifluoroethane.Compression set of 50% after 30 days at 400 oF may be considered too high for some sealing applications.
