Hybrid Sealing

Laufenberg’s Hybrid seals are flat seals of silicone with a core of PET or PP. Hybrid seals are found mostly in fuel cells to seal each individual cell and in water-cooling systems.

Hybrid seals are manufactured in almost all thicknesses.  At the moment thicknesses of 200, 250, 300, 650 und 700 µm are commercially available.  A thickness tolerance of a few microns is achievable using existing production technology.  Additionally the surface roughness is minimal which means that little surface pressure is required to ensure a high density. Assembly can be completed using a laser or water stream and with conventional cutting tools.
