Due to the high demands which are made on the safety of sealing compounds and the currently valid requests for highest leak-tightness it is necessary to have the appropriate know-how in choosing and installing the right seals.

There are whole series of demands which are made on flat gasket materials as well as the entire flange coupling to provide a reliable sealing compound.

  • Adaption to the irregularities of the sealing surface
  • Resistance against the medium to be sealed
  • Strength of the sealing compound
  • Leak-tightness
  • The maximum allowable surface pressure
  • Required gasket thickness
  • Use in the low temperature range


Conventional qualities

  • Rubber-bounded aramid fiber
  • PTFE
  • Graphite
  • Rubber

Conventional processing methods

  • Cutting
  • Milling
  • Punching
  • Plotting
  • Water jets




Plastic products are used in various industrial sectors. For example, they are found in the food industry as cutting boards, as storage boxes for chemical media or process boxes in the chemical apparatus and tank construction, as ventilation systems in the semiconductor and clean-room technology or as sliding and conveying component in the packing and beverage industry, as large-volume insulation components in the transformer or generator construction or as a storage tank supporting the transport of liquefied gases.

Common qualities

  • Polyethylene (PE)
  • Polycarbonate (PC)
  • Acrylic glass
  • PTFE
  • Polyurethane (PUR)
  • Polyamide (PA)
  • Polyoxymethylene (POM)
  • PVC

Conventional processing methods

  • Cutting
  • Milling

Elastomer and foam technology

Elastomer and foam products are used in almost all sectors of daily life, for example in the automotive industry, appliance industry, shipbuilding, tank and container construction as well as in the machine and plant construction. They are mainly used for sealing, insulating and protecting.

Common qualities

  • Viton
  • Silicon
  • Flexible polyurethane foam
  • PE foam
  • Accoustic insulation foam
  • Melamine resin foam

Conventional processing methods

  • Laminating
  • Plotting
  • Cutting
  • Punching


With help of our own manufacturing facilities we can assure our customers just-in-time deliveries for many commercial sealing materials. This has proved itself especially in case of shutdowns and overhauls.
