Abstract
1. Separator element 2. A separator element consisting of at least two types of layers of plastic material, one type of which layers is media resistant to mineral oils; and the other type of which layers has low permeability to gases or is gas-tight, wherein the two types of layers are firmly bonded to each other when in direct contact and form the elastically flexible separator element (12).
Claims11
A separator element consisting of at least two types of layers of plastic material,
- one type of which layers (28) is media resistant to mineral oils;
- and
- the other type of which layers (30) has low permeability to gases or is gas-tight,
- wherein the two types of layers (28, 30) are firmly bonded to each other when in direct contact, resulting the elastically flexible separator element (12).

- one type of which layers (28) is media resistant to mineral oils;
- and
- the other type of which layers (30) has low permeability to gases or is gas-tight,
- wherein the two types of layers (28, 30) are firmly bonded to each other when in direct contact, resulting the elastically flexible separator element (12),
- wherein the two outer layers (28) consist of one type of epichlorohydrin rubber and receive a layer (30) of the other type between them,
- characterized
- in that the layer (30) of the other kind between the two layers (28) of the one kind is made of isobutene-isoprene rubber;
- in that all layers (28, 30) consist of a single layer each;
- in that the respective type of layer (28, 30) is formed into the shape of a shell body as a partial body by means of thermoforming;
- and
- in that the three individual partial bodies are subsequently bonded together by vulcanization to form an overall shell body.
