Tap water
The flame retardant silicone rubber shows limited resistance to the following
chemicals at room temperature:
Acetic acid, conc.
Na-hypochlorite 10%
Ammonia 30%
Nitric acid 10%
Butanol
Phosphoric acid 10%
Ethyl acetate
Phosphoric acid 20%
Hydrochloric acid 37%, cold
-
Note:
If exposure to any of the above chemicals is demanded, it is recommended to
fi
rst test
the chemical in a hidden spot of the gasket.
The flame retardant silicone rubber shows little or no resistance to the following
