KLINGER®Graphite Laminate MLX

The graphite gasket with premium multilayer structure.

Klinger MLX is suitable for extreme conditions, especially for high pressure applications, high temperature and high compressive stresses.

This gasket has a multilayer structure consisting of 0.5 mm thick high-purity graphite foils (> 99 %) and 0.05 mm stainless steel foils. Testing confi a 6X increase in rigidity/handleability compared to conventional foil reinforced graphite gaskets. In a special process several layers of graphite and stainless steel foils are joined together, without using ny adhesives. A special impregnation ensures the improved sealing performance and excellent handling.

Basis

This material is composed of two layers of flexible graphite and a 0.3 mm thick high temperature resistant and fibre based insert.

Areas of application

KLINGER®Graphite Laminate MLX is recommended for applications in which graphite is the material of choice and minimal fugitive emissions are required.

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.
