The primary non-metallic, non-asbestos, materials used in "high temperature seals" include the following materials or a composition containing the following materials: flexible graphite, mica, vermeculite, fiberglass, and silica. There Temperature ratings do vary and in the case of flexible graphite it varies with the presence of oxygen.

If your looking for an elastomer that is high Temperature your probably looking for FKM / Viton, Aflas, Amerirez or Kalrez. When we go beyond elastomers the highest of which is Kalrez at approx. 600 F, then we get into what we consider high temperature seals.

1. Two sides are shielded with rubber seals, which are dust- proof. 2. Standard grease lubrication. 3. Belong to deep groove ball bearing, which has small friction, high limit speed, simple structure and low cost. 4. Mainly bear radial load. However, when the radial clearance of the bearing is increased, it can bear the combined radial and axial loads.

You must consider the PH value the seals will see. Are there chemicals present ? If so are they present continuously or just during a cleanout.

Because Grafoil® is so conformable it takes on the shape of any opposing flange which is why it seals so very well. With it's 0-14 ph capability it's compatible with most chemicals. From a temperature standpoint Grafoil© is also very flexible. Compatible with Cold (-400 F) to very hot (5400 F in Non-oxydizing atmosphere).850 F in oxydizing atmosphere. Grafoil® is also available in Oxidation resistant grades offering 975 F rateing.

High Temperature Seals   When discussing high temperature seals, the first thing that needs to be defined is just what we mean by a high temerature seal. Some customers consider a high temperature seals as one that will handle 500 F. Others feel 1000 F is high temp. So lets first break down what we mean. If your looking for an elastomer that is high Temperature your probably looking for FKM / Viton, Aflas, Amerirez or Kalrez. When we go beyond elastomers the highest of which is Kalrez at approx. 600 F, then we get into what we consider high temperature seals. In non-elastomer products, when looking for high temperature seals we offer several options. To know which of these materials is best suited for your application key factors must be considered. The first thing to be considered is what is the maximum temperature your application has. The primary non-metallic, non-asbestos, materials used in "high temperature seals" include the following materials or a composition containing the following materials: flexible graphite, mica, vermeculite, fiberglass, and silica. There Temperature ratings do vary and in the case of flexible graphite it varies with the presence of oxygen. To determine which of these materials is right for you several things have to be evaluated. You must consider the PH value the seals will see. Are there chemicals present ? If so are they present continuously or just during a cleanout. Are we sealing a liquid or a gas ? Is the seal dynamic or static ? If it's dynamic what is the speed and direction. What is the pressure ? Is the pressure continuous or are there spikes ? Once we know the details of your application we can help you with your high Temperature application. Grafoil® Flexible Graphite begins as graphite flake which is chemically expanded and then rolled into sheets. Those Grafoil® sheets are then stripped into tape or rolled and cut into gasket material (which we cut gaskets from). The tape form is often used to make die formed rings buy wrapping the Grafoil® around a mandrel and then forming it with a die. Grafoil® cannot be machined.
