Assessment of chemical resistance
To assess chemical resistance, the gasket materials were immersed in the media, if not otherwise mentionend, freely suspended, for 70 h at room temperatur . 10 % solutions were used in the case of diluted acids, alkalis and salts. We used saturated solutions for poorly soluble media.
Mixtures or non aqueons solutions may result in different assessment of chemical resistance. When selecting an asbestos-free gasket material, thermal and mechanical operating conditions must also be taken into account because they will affect the resistance of a material. In view of this, the data in the resistance charts should only be regarded as a guideline. They do not constitute a basis for any warranty claims. In cases of doubt, please contact us and inform us.
