Your Specialist in silicone

Silicone profiles in any geometry

Our competence - silicone profiles and silicone sealing profiles

Own tool and construction

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

Program

Our standard production program of silicone profiles includes various geometries.
Profile geometries without, as well as cross-sections with differently dimensioned hollow chambers can be produced:

as foam or compact silicone
with a Shore hardness between 15° and 90° Shore
in any RAL colour
platinum or peroxide crosslinked
with any material in our range (tear-resistant, heat-stabilizing, self-extinguishing)
with approval (food compliant, drinking water approved, etc.)

Silicone profile - geometries and cross section

U-profiles, T-profiles and complex cross-sections are offered. It is also possible to make up profile rings or profile frames from extruded silicone profiles. In any case, precise planning of the geometries and careful production execution are very important. Each silicone profile is a custom-made product that can meet the highest quality standards. This applies regardless of whether the geometries are standard profiles, square profiles or more complex variants.

Silicone profile - important properties

Silicone profiles that are to be used in the food or pharmaceutical industry must meet numerous requirements that are compatible with the legal regulations of the respective industry. Of course, all of this applies to the silicone profiles manufactured by J. Lindemann GmbH. Not only the geometries and the cross-section are important, but also the hardness. It can range from 15 to 90 Shore.

In addition, all silicone profiles are:

biocompatible
food safe
Approved for drinking water
odorless
tasteless
ozone resistant
weatherproof
aging resistant and
temperature resistant.

The latter can be particularly emphasized, because the silicone profiles are able to tolerate temperatures between -100 degrees Celsius and 300 degrees Celsius without damage. You have the opportunity to choose the color of the profiles themselves. There are no restrictions. The series size is a minimum of 25 meters, with no upper limits.

Silicone foam profiles

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.

Silicone round cords - Foam profiles - Foam round cords

The company J. Lindemann offers silicone round cords with diameters between 1 mm and 50 mm. The same applies to foam round cords.

The round cords are manufactured with a Shore hardness between 30° and 90°. On request, the round cords can be dyed in any RAL color. The compounds used for the round cords are peroxide or platinum cured according to customer specifications. At the customer’s request, the insertion of threads for strain-free fastening or production as foam round cords is possible.
Various approvals are available for our round cords on the base compounds.

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.
With regard to the physiological properties of silicone foam, there are two mixtures:

Fabrication of silicone profiles and cords

There are numerous options in this area. At the customer’s request, the profiles can be glued to form rings or frames. In addition, self-adhesive profiles can be applied or surface treatments can be carried out. Contact us, we will find an individual solution.

Fulfillment of important approvals and standards

Various approvals are possible for our profiles, round cords and foam round cords on the basic compounds.

For the food sector

All quality standards and norms of this industry must be met. This applies regardless of whether the silicone profiles are to be used for end applications in the bakery and restaurant or in systems and machines for the production of food.

For drinking water and sanitation

For the pharmaceutical sector

Special requirements apply in the pharmaceutical industry. For example, the profiles must not only be biocompatible, but also:

Furthermore, you must comply with the legal regulations that apply in the pharmaceutical industry:
