Anti-vibration & sealing

Cork-rubber composites deliver stable compression set and damping across temperature ranges that pure elastomers find challenging. From EV battery enclosures to HVAC ductwork, cork compounds maintain seal integrity where synthetics take a permanent set.

Vibration-damping gaskets fail in two predictable ways: the material takes a compression set and stops sealing, or it hardens in cold and loses conformability. Cork-rubber composites address both. The cork fraction provides dimensional stability and rebound; the rubber fraction provides conformability and fluid resistance.

In automotive and transport applications, cork-NBR composites cycle from –30 °C to 110 °C without the compression-set drift that causes pure NBR gaskets to leak after a few thousand cycles. The cork cells act as elastic spacers that prevent the rubber from collapsing under sustained load.

We supply the cork component — powder for fine gasket compounds, granules for thicker sheet stock — calibrated to the customer's binder and pressing parameters. The same cork fraction that works in a 1 mm die-cut gasket also works in a 6 mm vibration pad, at different loadings and with different binders.
