THE COMPANY

PRODUCT OVERVIEW

MATERIALS

Standard silicone tubing
In our extrusion plant, we can produce any dimensions up to an outer diameter of 190mm.
With this wide production ability, we can produce the desired cross-section for any customer requirement.
Standard silicone tubing is produced with a Shore hardness of between 30° and 90°.
On request, the tubing can be tinted in any RAL colour.
The compounds used for the tubing are vulcanised using a peroxide or a platinum cure.
Various licences are possible for our basic tubing compounds:

Assembly

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

  • Bonding to rings or frames
  • Cutting sections to length
  • Printing tubing
  • Hole punching
  • Surface treatment of extrudates

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
Simple shapes
Fabricable outer dimensions
Height in mm Width in mm
Up to 60mm Up to 220mm

Profiles with complex shapes and cross-sections according to customer specifications

Profile properties
Hardness 12° to 90° Shore
Colour Any RAL colour and colour matching to customer specifications
Thermal resistance -100°C to +300°C
Tear propagation resistance 16 kN/m to 45 kN/m
Elongation at tear 200 % to 1.000 %

Conforms to important licences and standards

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
