Gasket sheets

After choosing the right type of sealing sheets neccesary to your application, this is cut in order to obtain the right gasket. The choosing of the gasket is made by taking into consideration the following:

  • temperature
  • pressure
  • working environment
  • other critical conditions

Graphite sheets

Expanded graphite is used in high temperatures and has a very good chemical resistance. It is a soft material that has a better compression rate than gaskets made out of fiber mixtures, thus assuring a higher level of tightness.

Ceramic fiber sheets

Simple or reinforced, ceramic fibre sheets are usually used for isolation coatings of thermic aggregates in industries, such as: ferrous metallurgy, metallurgy, auto, chemical and petrol-chemical, energy, glass, ceramics, refractory, lignite, etc.

Elastomer sheets

Elastomer sheets are used only with low pressure applications. The elastomers will extrude during sealing because of the material’s incompressibility and low level of friction. Elastomer gaskets come under the form of a typical gasket with flange for applications that use water and oil at low pressures of up to 10 bar.

PTFE Sheets

PTFE is mainly used for its highly remarkable chemical resistance, both in the food and pharmaceutical industries. The usage of this material at high scale is though limited due to its predisposition to dilatation. Sintered or expanded PTFE is used for many applications that require sealing.

Asbestos-free fibre mixture gasket sheets (AF)

Compressed fibre materials are based upon production techniques used initially for compressed asbestos fibres, the so called IT techniques (gumI asbesT). After the banning of asbestos, no direct equivalent was found due to its unique chemical properties. Compressed fibre materials can be an alternative to the solution, but the range of use is much smaller than that of the asbestos and is much more dependent on the fibre mixture used during manufacturing.
