We supply different types of gasket sheets for wide range of temperature applications. All gaskets made of aramide and rubber mixture gasket sheets harden at temperatures above 200°C. Our gasket sheets even then remain elastic enough to compensate for thermal movements of flanges within the temperature range as specified. This is the basic requirement for keeping the sealing made of the gasket sheets tight, especially in the case of nodes subject to thermal cycles.
Another temperature threat to aramide and rubber gasket sheets at temperatures above 380°C is oxidation. This process causes elastomer binding the sheet to burn out. In order to prevent it, the elastomer component is to be isolated from chemical effects of both sealed medium and ambient oxygen.
Over 380°C up to 500 °C we offer graphite gasket sheets, and over 1000 °C we can supply mica gasket sheets for extra high temperatures.
