Sealing underbody battery housings efficiently, precisely, and safely
Complete solutions for e-mobility
The battery housings installed in the car underbody are seamlessly sealed with the room temperature cross-linking 2-component polyurethane foams from the SONDERHOFF FERMAPOR K31 product family. They protect the electric batteries against moisture, corrosion, and dust. They also dampen vibrations and are resistant to temperature and chemicals on the polyurethane material specifics. Protection against these influencing factors helps to improve the long life of the E-batteries.
The die-cast aluminum housings for holding the electric batteries are sealed efficiently, precisely, and securely using FIPFG (Formed-In-Place-Foam-Gasket) technology. The CNC-guided mixing head of the SONDERHOFF mixing and dosing machine moves along the housing geometry and applies the 2-component polyurethane sealing foam SONDERHOFF FERMAPOR K31 with precise contours. After foaming, a seamless foam gasket is produced which cures at room temperature.
The elastic foam cell structure of the seal is compressed when the battery housing cover is screwed tight. Thus, the housing and cover are sealed to each other. The excellent resetting ability of the foam sealing allows the housing to be opened and re-closed repeatedly for maintenance purposes. At the same time, the sealing effect of the housing seal is maintained by the consistently good compression of its foam structure. The housing is sealed, and the batteries are protected against splash water and weather influences.
