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.
