THE COMPANY

PRODUCT OVERVIEW

MATERIALS

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

Program

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

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

Round cords

Round silicone cords
Our selection of round silicone cords and sealing cords are available in diameters:

  • from 1mm
  • to 50mm
Round cords are produced with a Shore hardness between 30° and 90°. On request, round cords can be tinted in any RAL colour. The compounds used for the round cords are vulcanised using peroxide or platinum cures, according to customer specifications. The introduction of fibres for non-extensible attachment and production as foam round cord is possible.
Various licences for the basic compounds are available for our round cords:

For the food industry

  • BfR XV Silicone
  • FDA § 177.2600
  • 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 1099

Assembly

The further processing of round cords into assembled articles is required in many applications. After extrusion, numerous finishing steps can be carried out on the round cords:

  • Bonding to rings or frames
  • Cutting into sections
  • Hole punching
  • Surface treatment of the extrudates

Round foam cords

Just like tubing, round cords can be foamed using special foaming agents.
Round foam cords can be produced in the same dimensions as compact cords.
Depending on the dosage of the foaming agent, various foam types are possible, with different Shore hardnesses and density types.
Regarding the physiological properties of the silicone foam, there are two compounds:

  • Technical, NON-FDA quality
  • FDA quality
