Profiles in any geometry

The production of custom silicone sealing profiles is our strength.

Own tool and construction

Our own tool and construction allows a quick implementation of customer-related silicone profiles.
For specific cross-sections, we offer:

Profiles -without-Velcro-Silicon-Lindemann
Profiles -transparent hollow profile silicone lindemann
Sealing Profile Frame Silicone Lindemann

Program

Our standard silicone profile production program includes various geometries.
Simple as well as cross-sections with differently dimensioned hollow chambers can be produced:

foam profile

In addition to the standard properties of silicone, certain applications require additional mechanical requirements. These are achieved by a foam cell structure.

Our foam profiles are foamed with special propellants. The structure of the foam is closed-cell.

Due to the foaming, the profiles have a:

The foam profiles can be produced in any geometry:

Depending on the dosage of the propellant, different foam types are possible.

Assembly of profiles

The following finishing steps can be performed from the endlessly produced silicone seals after extrusion:

Silicone round cords

Our selection of silicone round cords or sealing cords extends over a diameter:

The round cords are made with a Shore hardness between 30° and 90°. On request, the round cords can be dyed in any RAL colour. The compounds used for the round cords are vulcanized peroxide ally or platinum crosslinked according to customer specifications. As a special production, the insertion of threads for stretch-free fastening or the production as a foam round cord is possible.
Various approvals for the basic mixtures are available for our round cords.

For drinking water and sanitation

For the pharmaceutical sector

Assembly

The further processing of the round cords as ready-made articles is required in many applications. After extrusion, various finishing steps can be performed on the round cords:

Foam round cords

Similar to the hoses, round cords can be foamed with special propellants.
The foam round cords can be manufactured in the same dimensions as a compact cord.
Depending on the dosage of the propellant, different foam types are possible, with different Shore and density types.
