KLINGER® top-chem2000

Characteristic & main applications
The universal heavy-duty gasket for an extremely wide range of applications in the chemical and petrochemical industries as well as in the ship building industry for chemical tanker applications. Due to its unique load bearing properties it is able to withstand high temperatures and pressures and it is the only PTFE gasket with a Fire Safe Certificate. It is also the first choice in the food sector and in the pharmaceutical industry, for steam applications and in oxygen pipes, and where special requirements are made acc. to TA Luft (German Clean air regulation).
KLINGERtop-chem-2000 has excellent chemical resistance in strongly acidic and alkaline applications and offers exceptional performance in applications with high mechanical requirements at high temperatures.

pT diagram
The Klinger pT diagram provides guidelines for determining the suitability of a particular gasket material for a specific application based on the operating temperature and pressure only. Always refer to the chemical resistance of the gasket to the fluid.
