Available Configurations – Cork Sheet Grades & Sizes
Kaxite offers cork sheet in a variety of granule sizes and density grades to suit diverse application requirements. All sheets are manufactured from high‑quality natural cork with full material traceability.
Granule Grade Classification
Cork sheet can be classified by granule size, which affects surface texture and physical properties:
- ▪ Small Granule (30‑60 mesh) – Fine texture, smooth surface
- ▪ Medium Granule (12‑24 mesh) – Standard texture, balanced properties
- ▪ Large Granule (8‑12 mesh) – Coarse texture, high compressibility
Density Grade Classification
Different density grades offer varying levels of compressibility, resilience, and mechanical strength:
- ▪ Low Density (~270 kg/m³) – Maximum compressibility, ideal for light sealing
- ▪ Medium Density (~320 kg/m³) – Balanced properties for general use
- ▪ High Density (~380 kg/m³) – Greater strength and durability for demanding applications

Key Advantages of KXT B601 Cork Sheet
Superior Compressibility – Cork sheet compresses easily to fill gaps and irregularities, providing a tight seal even on damaged or uneven flange surfaces.
Excellent Recovery – After compression, cork rebounds to its original thickness, maintaining sealing force over time and reducing the need for retightening.
Natural & Eco‑Friendly – Cork is a renewable, biodegradable material with a low environmental footprint. Our sheets are 100% formaldehyde‑free.
Fluid Resistance – Naturally resistant to water, oils, and many common solvents, ensuring reliable performance in demanding environments.
Vibration Dampening & Sound Insulation – Cork’s cellular structure absorbs shock and reduces noise transmission, making it ideal for machinery mounts and acoustic applications.
Easy to Cut & Fabricate – Cork sheet can be easily die‑cut, waterjet cut, or machined into custom shapes and gaskets without special tooling.

Frequently Asked Questions About Cork Sheet
- Q: What is cork sheet made from?
- A: Cork sheet is manufactured from clean, granulated natural cork bark that is mixed with a synthetic resin binder and compressed into sheet form under heat and pressure. The result is a resilient, compressible material with excellent sealing and insulation properties.
- Q: What temperature range can cork sheet withstand?
- A: Cork sheet is typically suitable for continuous service from ‑40°C to +100°C. For higher temperature applications, please consult our technical team for material selection guidance.
- Q: Is cork sheet resistant to water and oil?
- A: Yes. Cork sheet has natural resistance to water, oils, and many common solvents due to the suberin content in cork and the resin binder. This makes it suitable for applications where exposure to these fluids is expected.
- Q: What is the difference between cork sheet and cork‑rubber sheet?
- A: Cork sheet is made from cork granules bonded with a resin binder, while cork‑rubber sheet combines cork with rubber (typically nitrile or neoprene) to provide enhanced oil resistance and sealing performance. Cork‑rubber is often preferred for dynamic sealing applications, while cork sheet is a more economical choice for static gasketing and insulation.
- Q: Can you supply cork sheet in custom sizes and shapes?
- A: Yes, we offer complete customization including custom sheet dimensions, thicknesses, granule sizes, density grades, and die‑cut shapes. We also offer adhesive‑backed sheets for easy installation. Contact us with your specifications for a custom quote.
