Cork-Nitrile
Cork-Nitrile is a composite material that combines the excellent sealing properties of natural cork with the superior oil and fuel resistance of nitrile, creating an ideal material for gasket and packing applications in industrial environments.
With excellent oil resistance and good performance across a wide temperature range, this material is perfect for engine gaskets, hydraulic systems, and automotive applications where reliable sealing against fluids and lubricants is required.
Superior Sealing Properties
Cork-Nitrile stands out for its excellent sealing and chemical resistance properties:
- Excellent oil resistance and fuels
- Wide operating temperature range (-20°C to 120°C)
- Good resistance to acids and alkalis
- Excellent sealing capability and compressibility
- Vibration damping properties and absorption
These properties make it indispensable in automotive applications, hydraulic systems, engine gaskets, and any environment requiring reliable sealing against oils and industrial fluids.
