Resistance

Resistance of silicone rubber
against chemicals and solvents

The storage of the vulcanised products was 7 days with temperatures
shown in the table according to DIN 53521.
The measurements after storage were made in expanded condition.

The following types were tested:

The letters shown in the column
‘judgement’ indicate:

1 -- standard grading

2 -- grading with improved chemical resistance

3 -- fluorine silicone India rubber

A. Vulcanised products can be used without

restrictions under the given circumstances.

B. Vulcanised products are usable only for some purposes.
The degree of strain is decisive. There are clear differences between momentary and constant action on the product
as well as between complete immersion into the medium
and slight contact of it.

C. Vulcanised products should not be used under the given
conditions.
