Cork Rubber Sheet for Reliable Sealing & Damping
Cork rubber sheet is a composite material manufactured by bonding granulated cork with synthetic rubber binders such as nitrile rubber (NBR), neoprene (CR), EPDM or SBR. The combination of cork and rubber provides a unique balance of compressibility, recovery, oil resistance and vibration damping properties.
Cork rubber sheet is widely used for gaskets in automotive oil pans, valve covers, transmission pans, and for general industrial sealing where low to medium clamping loads are applied. The cork content provides excellent conformability to irregular surfaces, while the rubber binder imparts oil, fuel and chemical resistance.
We supply cork rubber sheet for overseas distributors, industrial buyers, gasket manufacturers, maintenance companies and OEM customers, with different binder types, cork granule sizes, densities, thicknesses, sheet sizes and custom cutting available according to specification.
Excellent Compressibility & Recovery
Cork granules provide high compressibility to seal uneven surfaces under low bolt loads.
Oil & Fuel Resistance
NBR or CR bonded grades resist oils, fuels and hydrocarbon fluids for automotive sealing.
Vibration Damping & Noise Reduction
Cork rubber sheet absorbs vibration and reduces noise transmission in mechanical assemblies.
Low Cost Sealing Solution
Economical alternative to solid rubber or fiber gaskets for low to medium pressure service.
Material Advantages
Why Choose Cork (Rubber) Sheet?
Cork rubber sheet provides an optimal combination of compressibility, oil resistance, vibration damping and cost-effectiveness for a wide range of sealing and cushioning applications.
01
High Compressibility
Cork rubber sheet compresses easily under low clamping force, filling surface irregularities and providing an effective seal on rough or machined surfaces.
02
Good Recovery
The rubber binder provides resilient recovery after compression, maintaining seal integrity under fluctuating loads and thermal cycling.
03
Oil & Fuel Resistance
NBR and CR bonded grades offer excellent resistance to oils, fuels, greases and hydrocarbons, making them suitable for automotive and industrial oil sealing.
04
Vibration Damping & Noise Reduction
The cellular cork structure absorbs mechanical energy, reducing vibration transmission and noise in machinery and automotive components.
05
Multiple Binder Options
Choose from NBR, CR, EPDM or SBR binders to match specific oil, weather or temperature requirements.
06
B2B Industrial Supply
Suitable for industrial distributors, gasket fabricators, OEM customers, maintenance companies and bulk purchasing.

Selection Guide
How to Choose Cork (Rubber) Sheet
The correct cork rubber sheet grade and dimensions should be selected based on media, temperature, pressure, surface condition and required compliance.
01
Binder Selection
Choose the rubber binder based on the service media: NBR for oil resistance, CR for weather and moderate oil, EPDM for water and ozone resistance.
02
Density & Cork Content
Higher cork content provides greater compressibility; higher rubber content provides better oil resistance and tensile strength. Select density based on sealing requirements.
03
Thickness & Sheet Size
Thicker sheets compensate for rough or uneven surfaces and provide better vibration damping. Specify sheet dimensions for efficient gasket cutting.
04
Operating Conditions
Confirm temperature, pressure, chemical exposure and mechanical load to select the optimal grade and density.
Manufacturing
Controlled Production for Consistent Quality
Consistent cork granule size, binder distribution, sheet density and thickness tolerance are critical for reliable cork rubber sheet performance.
PROCESS / 01
Material Mixing
Granulated cork is mixed with the selected rubber binder and additives to achieve the specified compound and density.
PROCESS / 02
Calendering / Molding
The mixed compound is calendered or molded into sheets of uniform thickness and density under controlled pressure and temperature.
PROCESS / 03
Curing & Inspection
Sheets are vulcanized to develop final properties, then inspected for thickness, density, tensile strength and surface quality.
PROCESS / 04
Cutting & Packaging
Sheets are cut to standard or custom sizes, and packaged with protective interleaving for export and storage.
