CHEMICAL RESISTANCE
AND
FLUID COMPATIBILITY
KALREZ@ perfluoroelastomer parts combine the elastomeric properties of VITON” fluoroelastomer with the
chemical resistance of TEFLON@ fluorocarbon resins. Due to its unique properties, KALREZ perfluoroelastomer
parts should be considered for service in all applications and environments where dependable long-term service
is desired, as well as in hot and/or aggressive environments which are beyond the serviceability of common
elastomers.
This guide is intended to provide assistance in determining the suitability of six commercially available
elastomers-nitrile (NBR). ethylene propylene (EPDM), silicone (SI), fluorosilicone (FSI). vinylidene fluoride based
fluoroelastomer (FKM) and KALREZ perfluoroelastomer-for service in over 1,600 chemicals and fluids. The
criteria used for these ratings included volume swell resistance based on laboratory immersion testing, laboratory aging tests. actual field experience and informed judgments based on experience in similar chemical groups.
The ratings for the five common elastomers are based on
published literature and are offered for general comparative purposes only-we cannot guarantee their
accuracy nor assume responsibility for their use. The ratings for these five elastomers may be overly optimistic for
elevated temperature and/or high concentration applications since many are based on ambient temperature testing. Suitability of these elastomers for service at elevated
temperatures rapidly diminishes since higher temperatures Increase the effects of chemicals on both the base
polymer as well as the crosslink systems. Serviceability is
further limited by the upper service temperature limit of
each polymer, nominally 107°C/2Z50F, 149°C/3000F,
204°C/4000F, 190°C/3750F. and 204Y/400°F for NBR.
EPDM. SI. FSI and FKM respectively-note that these limits
are based on air oxidative stability; limits for specific chemicals are often much lower. Additronally. these elastomers
are commercrally available in different grades of polymer
and can vary in compound Ingredients-different grades
and compounds within a polymer class can have significantly different performance characteristics.
As an example, consider a specific case involving an FKM.
whose upper service temperature limit is nominally
204°C/4000F. Many sources will show an ‘A” rating for
FKM surtabrlity In toluene service, a common chemical.
However, immersion testing of commonly available FKM
o-rings at a slightly elevated temperature of 50°C/1220F
for 168 hours shows a volume swell exceeding 24% and
significant loss of physical properties-surely warranting a
“C” rating. Similar tests with KALREZ perfluoroelastomer
parts, however, show that the “A” rating is maintarned
beyond 100°C/2120F.
CHEMICAL RESISTANCE TABLES

Since KALREZ has outstanding chemical resistance, it withstands nearly all classes of chemicalsbecause of the combination of the highthermalstability and excellent chemical resistance, the KALREZ
perfluoroelastomer parts rating may be conservative,asactualfield experienceandthe example has
demonstrated.
In comparing the chemical and fluid resistance of
KALREZ perfluoroelastomers to that of TEFLON fluorocarbon resin, certain differences should be kept in mind:
RATING SYSTEM
A
B
1) KALREZ is an amorphous low modulus rubber whereas
TEFLON is a crystalline high modulus plastic. In fluid
environments where high permeation occurs, KALREZ
will probably swell to a greater extent than TEFLON
even though the polymer is not chemically attacked.
Environments in which this is most noticeable are fully
halogenated solvents and FREON@. Serviceability of
KALREZ in these environments will be dependent upon
the specifics of the application.
2) As with all elastomers, it is necessary to compound
w
KALREZ perfluoroelastomers with fillers and curatives
to gain desired mechanical properties for functionality.
In a limited number of environments, even though the
polymer is stable, the fillers and curative systems may
interact with the chemicals. However, since the level of
fillers in KALREZ perfluoroelastomers is much lower
than in most other elastomers, such filler interactions
are generally negligible with KALREZ parts, Where such
interactions can occur, such as in highly oxidative
environments, service performance is dependent on the
conditions of the application and may be affected by
choice of compound.
Since each and every application is unique, it is recommended that users of KALREZ perfluoroelastomer parts
always conduct their own evaluations to determine the
suitability of KALREZ for their application. Because of laboratory constraints and differences in field applications. the
results shown in this guide may be based on conditions
which may not necessarily reflect actual operating environments for a specific application. Additionally, many elastomeric materials may show excellent chemical resistance
to pure reagents in relatively short-term laboratory tests.
However, they may fail in actual service because of chemical
attack by additives and/or impurities. KALREZ perfluoroelastomer parts. with their near universal chemical
resistance, provide an extra degree of safety against these
unknown corrosive influences.
A Case History booklet is available from your Authorized
KALREZ Distributor detailing proven performance of
KALREZ parts in over 100 specific chemical applications.
Information on test performance in a limited number of
specific chemicals is also available through your Authorized
Distributor.
C
U
Elastomer shows little or no effect (generally
less than 10% swell) after exposure to the
chemical; slight swelling or loss of properties
may occur under severe conditions but this
should not affect performance.
Elastomer may be affected by the chemical
after exposure, as evidenced by slight visible
swelling and/or loss of physical properties;
in B-rated cases, KALREZ parts will often
perform satisfactorily long after other elastomers have failed.
Elastomer is affected by the chemical after
exposure, as evidenced by moderate to severe
swelling and/or loss of physical properties;
limited functionality is possible but must be
determined by testing.
Elastomer is not suitable for service in the
chemical.
Where no rating is shown, insufficient information
is available to make a judgment.
An asterisk (*) next to a KALREZ perfluoroelastomer rating indicates that differences may exist
between KALREZ compounds in certain applications
which could affect relative performance-consult your
Authorized Distributor or Du Pont for compound
selection. For such environments, other elastomers
generally have very limited serviceability.
CAUTION
KALREZ perfluoroelastomer parts, like all fluorinated products, should not be exposed to molten or gaseous alkali
metals, such as sodium and potassium, because a highly
exothermic reaction may occur.
At elevated temperatures above 100°C/2120F, service
life may be significantly reduced in fluids containing high
concentrations of some diamines. nitric acid and basic phenols. KALREZ parts should always be tested for suitability.

Generally, KALREZ parts ratings are applicable up to 100°C/2120F-however, in many chemicals, KALREZ parts will be functional at higher
service temperatures. Testing is always recommended for each proposed use of KALREZ since actual application conditions may vary. Please

The Inform&on in this publratlon has been prepared from laboratory tests on KALREL~ perfluoroelastomer. These tests establish that in many enwronments KALREZ has properties of thermal and
chemical resistance superior to those of other elastomeric materials However, because certain appllcatlons may involve conditions not present in the laboratory. Du Pant makes no warranty that any
