Description
6.4 Chemical components
The standard plastic types used are polyethylene (PE) and polypropylene (PP). As a matter of principle, the rotor mate-
rial is the indicator for the selection.
Note:
The list “COMPATIBILITY WITH CHEMICAL AGENTS” is available in our online catalogue. This list has been
produced to the best of our knowledge, but we cannot guarantee the correctness of all statements.
Examination of the media to be transported is a matter for the plant operator. Here, it is merely a question
of a recommendation.
