Profiles in all shapes
Our strength is the production of customer-specific silicone seal profiles.

Own building of tools and constructions

Our own building of tools and constructions allows fast realisation of made-to-order silicone profiles.
In the case of special cross-sections, we can:

  • Create technical drawings
  • Build the tools
  • Produce quality samples


Our standard manufacturing program in silicone profiles covers various shapes.
Both simple and complex cross-sections with differently sized cavities can be produced as:

  • Foam or compact silicone
  • Shore hardnesses between 15° and 90° Shore
  • In every RAL colour
  • Platinum- or peroxide-cured
  • Using every material in our range (tear-resistant, thermally stabilising, self-extinguishing)
  • With licences (conforming to food laws, licensed for drinking water, etc.)

Profiles with simple shapes

  • Square profiles
  • Upright profiles
  • Trapezoidal profiles
  • Flat bands

  • EG VNr. 1935/2004

For the drinking-water and sanitation industry

  • KTW A Kalt- und Warmwasser
  • DVGW W 270
  • WRAS
  • 3 A Sanitary Standard

For the pharmaceutical industry

  • USP Class VI
  • ISO 10993

Foam profiles

In addition to the standard properties of silicone, specific applications have additional mechanical requirements, which are achieved through a foam cell structure.

Our foam profiles are foamed using special foaming agents. The foam has a closed-cell structure.

Through foaming, profiles have:

  • Significantly lower density
  • Greater compression
  • Greater resilience
Foam profiles can be made in any shape:

  • Standard shapes, such as a square profile
  • Complex shapes
Depending on the dosage of the foaming agent, different foam types are possible.

Profile foam properties
Shore hardness A 5° to 30°
Density g/cm3 0,25 to 0,65
Regarding the physiological properties of the silicone foam, there are two compounds:

  • Technical, NON-FDA quality
  • FDA quality

Assembling profiles

The following finishing steps can be carried out on the continuously produced silicone seals after extrusion:

  • Bonding to rings and frames
  • Application of self-adhesive units as mounting aids
  • Surface treatment of the extrudates
