KLINGERantistick (A/S) on request
Suitable for temperatures up to approx. 450°C.
In an inert atmosphere (no admission of oxygen) even suitable for higher temperatures.
Fields of application:
Particularly suitable under high chemical and thermal loads. KLINGERgraphite-laminate PSM
keeps its physical properties in the entire field of application.(Resistance table see back.)
Suitable for media used in the food industry. In accordance with Landesgewerbeamt von Baden-
Württemberg and the requirements of the German Food Act.
The function and durability of the Klinger gaskets depends largely on
the installation conditions which we as manufacturers cannot influence.
We therefore only guarantee a perfect condition of our material.
Material structure:
A KLINGERgraphite foil is rolled on a 0.10 mm thick tanged stainless
steel sheet (1.4401*) without adhesive.
Order example:
1 sheet
KLINGERgraphite-laminate PSM
1500 or 1,000 x 1,000 x 1.5 mm.
Other delivery options
Rings and other finished gaskets are also available in any size and corresponding sheet thicknesses.
Tests and approvals:
DIN-DVGW approval no. NG-5124AT0417.
BAM approval in accordance with UVV 28, oxygen (VBG 62) tested up to 130 bar
and 200°C, also for use with liquid oxyen, WRc approval.
Anti-stick finish:
The KLINGERgraphitelaminate PSM is available with KLINGERantistick. (A/S) A finish which keeps its stability
even at high temperatures and causes no organic contaminations of the pure graphite.
0.8 mm, 1.5 mm, 2mm, and 3 mm thick sheets are also available.
