ZI-211 SI Gasket

Silicone-Gasket
(V 2018-07-16)


Use
Access doors with silicone gasket

Material
Silicon profile made of WZ 2986. Although there are other gaskets suitable for use in the food industry, silicone is very widespread due to its mechanical properties, its smooth, easy-to-clean surface, and its high temperature resistance. Color: transparent.

The resistances are applicable only to the gasket material, and not the adhesive. The acrylate dispersion adhesive has a relatively low resistance to chemicals.

The provided information have been derived from brochures and are valid by a temperature of 20°C. Different temperatures can reduce the resistance levels. Please also note the somewhat limited life expectancy of elastomers due to aging. Controls at regular intervals are recommended.

Chemicals and oils are available in very different qualities. Their properties vary depending on their concentration, operating temperatures, possible mix with other chemicals and the eventual presence of impurities. This is why gasket manufacturers only provide general information about the resistance of their products to various chemicals. In view of the above it is advisable that the client runs some tests in order to assess if the gaskets are suitable for the intended application. We regret not being able to provide more precise information.

REACH
Does not contain any substances (SVHC) which could be of concern according to the REACH extended list dated 13-01-2010.
