KLINGER®top-chem 2000

Exceptional performance at high mechanical requirements

KLINGER top-chem 2000 is a universal heavy-duty gasket, which offers an exceptional performance in applications with high mechanical requirements at high temperatures.

Basis

PTFE gasket filled with SiC (Silicon carbide).

Areas of application

Excellent resistance in strongly acidic and alkaline applications as well as to steam and oxygen. Suitable for an extremely wide range of applications in the chemical and petrochemical industry, as well as in the ship building industry for the transport of chemicals.

Key features

Mechanically stable
Resistant to creep and cold flow
Consistent material composition

Benefits

Resists high surface pressures also at elevated temperatures
High retention of the bolt load
Superior chemical resistance
No ageing of the material

Function and durability

The performance and service life of KLINGER gaskets depend to a large extent on proper storage and fitting – factors beyond the manufactor’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also take note of our Installation manual.
