Resistance

Environmental simulation
Test procedure

Chemical resistance in general means the resistance of materials against the influence of chemicals. Contrary to what happens in the case of corrosion no original material is lost here, which typically applies to plastics and elastomers.



The term biological resistance describes the extent to which materials may be disintegrated by micro-organisms such as bacteria, algae or fungi.

There are many applications in which the respective materials must not support bacteria or fungi growth.
