Silicone profiles

Nearly all industries use silicone profiles today. The number of different geometries is almost unlimited for our customers. For example, regular applications for our silicone profiles include sealing profiles or edge protections. The special properties like biocompatibility or food resistance make silicone the right material for a wide range of applications.

As a manufacturer of silicone profiles, Siltec offers all common shapes such as U-profiles, H-profiles or T-profiles as well as complex cross-sections with several hollow chambers. In 40 years of company history, Siltec has already implemented more than 7000 profile geometries. Consequently we offer an extensive design and development experience for creating new profiles with our customers.

Siltec also manufactures profile frames and profile rings from extruded silicone profiles, on request. For this, we can mold or impact vulcanize the corners to facilitate a particularly flexible and durable connection. Shaping corner tools allow us to realize many geometries, which increase the performance especially when used as silicone seal.
