Sonderhoff1018The new FIP CC technology (Formed-In-Place Closed-Cell) from Sonderhoff brings together the high water resistance of the silicone world and the attractive material costs of the polyurethane world. The foam seals "Fermapor CC" based on PUR are room temperature crosslinking 2-component systems that use the FIP CC foaming process to form a very fine-cell, predominantly closed-cell, soft foam seal.

They have a very low water absorption and harden without oven or moisture. Unlike comparable mixed-cell seals, the CC foam seal requires less compression with the same sealing performance. A robust, abrasion-resistant surface of the CC foam seal withstands possible mechanical stresses in the parts handling. Even after damage to the surface, the water absorption changes only slightly.

The CC seal made of PU is very weatherproof and keeps tight even with ice water. The FIP CC application process with the new DM 402 CC dosing system follows the well-known FIPFG process, which is the production standard in many industries. What is new is that by physical foaming the CC foam already comes with the dosage in its almost complete sealing dimension on the component. As a result, the user can check immediately after applying the seal whether the seal has been applied at the same height over the entire component contour. Fermapor CC is therefore particularly suitable for 3D applications and process-oriented quality control.
