Within normal use temperatures, fluoro-
plastics are attacked by so few chemicals
that it is easier to describe the exceptions
rather than list the chemicals with which
TexFluor™ is compatible.
DO NOT USE FLUOROPLASTICS WITH THE
FOLLOWING:
ƒ
ƒ
Alkali metals such as elemental sodium, potas-
sium, lithium, etc. The alkali metals remove
fluorine from the polymer molecule.
ƒ
ƒ
Extremely potent oxidizers, fluorine (F2) and
related compounds (e.g., chlorine trifluoride,
CIF3). These can be handled by TexFluor™, but
only with great care, as fluorine is absorbed into
the resins, and the mixture becomes sensitive
to a source of ignition such as impact.
ƒ
ƒ
80%
NaOH (Sodium Hydroxide) or KOH (Po-
tassium Hydroxide), metal hydrides such as
Borances (e.g., B2H6), Aluminum Chloride,
Ammonia (NH3), certain Amines (R-NH2) and
imines (R=NH) and 70% Nitric Acid at tempera-
tures near the suggested service limit.
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THE
