ZI-206 KF Gasket

Ceramic Fibers Gasket KF (ZI-206)

This gasket is made of different components which show different characteristics:

 -   the ceramic fibers,
 -   the glue holding the fibers together and
 -   the double-sided adhesive-tape used for self-adhesive gasket version.

The self-adhesive gasket version is mostly used with rectangular duct connections, SR and SS joining clips as well as access doors. The ceramic fibers gasket used with MU overcollars is not self-adhesive. These are important aspects, as they affect the temperature resistances for instance.

Gasket Material

Ceramic fibers (Calcium Magnesium Silicate Base)

Color: white
Ceramic fibers temperature resistance: -20°C up to +900°C (max. 1200°C for a short period).
Temperature at which the bonding agent holding the fibers together loses its properties: ≈ +250 °C.
Fire class: EN 13501-1 A2-S1-d0, DIN 4102-1 A2 (non-flammable with parts of flammable substances)
Asbestos-free and high bio persistence (degradable in the body).
Does not fall under Directive 97/6/EC Note Q.

Self-adhesive Double-sided Tape

Temperature resistance of the self-adhesive double-sided Tape: -40°C up to +100 °C

Silicon Free

All self-adhesive products are usually fitted with a siliconized protective foil applied over the bounding surface. To install the product this foil must be removed: it is therefore not part of the product. The gasket material itself is silicon-free. It is possible however, that silicon traces are detected, as they can be transmitted to other parts during handling. An absolute silicon-free guarantee can, for that reason, not be given.

Important Considerations

It is recommended to replace the KF gasket if it has been subjected to temperatures above 200°C, as it might have lost its mechanical properties and crumble.

Resistances to Chemicals

Chemicals are available in many 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. Fibers can be soaked with liquids. The resistances are valid for the fibers only, and not for the adhesives or other components. The adhesives have only a limited resistance against 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.

RoHS, REACH

RoHS directive 2011/65/EU: fulfilled.
These products do not contain any substances from the candidate list (SVHC January 17, 2022) according to Article 59 of Regulation (EC) No. 1907/2006 "REACH" above 0.1% by mass.
