Weather and temperature
resistant. Can be used both
indoors and outdoors.
For continuous use between
-40°C and +100°C. (Cf.
natural rubber: Max.
+70°C). Somewhat higher
temperatures for short pe-
riods of time (+130°C for
approx. 1 hour).
After 168 hours at +70°C.
Property changes:
Hardness +2 ° Shore
(+3%)
Ultimate tensile strength
-9%
Elongation at break -17%
After 72 hours at +100°C.
Property changes:
Hardness +7 ° Shore
(+11%)
Ultimate tensile strength
-19%
Elongation at break -22%
Not self-extinguishing.
Burning rate approx. 2 cm/
min. Conforms to require-
ments for use in car bodies.
Normally resistant to:
Detergents
Highly oxidizing chemicals
such as:
Ammonia
Dilute phosphoric acid
Dilute cromic acid
Dilute nitric acid
Dilute hydrochloric
Dilute sulphuric acid
Other chemicals such as
Film developer
Glycol
Cutting fluid (emulsion)
Only slightly affected by:
Concentrated acids at room
temperature
CR
TET-C
Black
Weather and temperature
resistant. Can be used both
indoors and outdoors.
For continuous use between
-25°C and +95°C. Some-
what higher temperature
for short periods of time.
After 72 hours at +100°C.
Property changes:
Hardness +6 ° Shore
(+10%)
Ultimate tensile strength
-8%
Elongation at break -16%
After 72 hours at +125°C.
Property changes:
Hardness +13 ° Shore
(+13%)
Ultimate tensile strength
-12%
Elongation at break -35%
Self-extinguishing.
Tested as per IEC standard.
Approved for installation
on ships.
Normally resistant to:
Aliphatic hydrocarbons
Alkalies
Alcohols
Dilute acids
Only slightly affected by:
Acetone
Ammonia
Freon
Glycol
Sodium hydroxide
Good resistance to mineral
oils. Other petroleum pro-
ducts such as grease and
wax have very little effect.
But should not be used in
direct contact with petrol
(gasoline).
PEH
