Frequently Asked Questions (FAQ) About Cork Sheet
We’ve compiled a list of the most common questions we receive about cork sheet materials. If you have a question not covered here, our Kaxite Sealing technical support team is always ready to assist.
Q: What makes cork sheet a sustainable material choice?
A: Cork is a remarkably eco-friendly resource. The bark of the cork oak tree is harvested every 9-12 years without harming the tree, which can live for over 200 years. This process promotes carbon sequestration and supports biodiverse ecosystems. Kaxite Sealing sources its cork from responsibly managed forests, ensuring a fully renewable and biodegradable (when untreated) product lifecycle that minimizes environmental impact.
Q: How do I select the correct density and thickness for a gasket application?
A: The selection depends on flange surface finish, bolt pressure, and the medium being sealed. For smooth flanges and low-pressure water/air applications, our KAX-NATURAL grade (3-5mm) is often sufficient. For rough cast surfaces, higher pressures, or oils/fuels, KAX-DENSE grade (3-6mm) is recommended as it resists extrusion better. Always ensure the cork sheet thickness is sufficient to fill the flange gap imperfections under compression.
Q: Can Kaxite Sealing cork sheet be used for high-temperature applications?
A: Our standard cork sheets are reliably used in continuous service up to 120°C. For short-term exposure, they can withstand peaks of 150°C. Prolonged exposure above this range can cause the natural resins to harden and reduce resilience. For higher temperature needs, we recommend exploring our composite materials or specific high-temperature treated cork options. Always verify the temperature rating against your specific operating conditions.
Q: How do I cut and install cork sheet gaskets effectively?
A: Cork sheet is easy to work with. For gaskets, place the sheet over the flange and tap gently with a mallet to create an imprint. Cut along the inside of bolt holes first, then the outer profile using a sharp utility knife, scalpel, or die-cutting tools for production. The surface should be clean, dry, and free of old gasket material. Apply a thin, even layer of appropriate gasket sealant if specified. Tighten bolts evenly in a crisscross pattern to the manufacturer's torque specifications to ensure uniform compression.
Q: Is your cork sheet resistant to mold, mildew, and pests?
A: Yes, naturally. Cork contains suberin, a waxy substance that makes it inherently resistant to moisture absorption, mold, mildew, and pests like termites. This makes Kaxite Sealing cork sheet an excellent choice for building applications in areas prone to humidity, such as sub-floors, walls, and roofing underlayment, without the need for toxic chemical treatments.
Q: What is the difference between cork sheet and cork roll?
A: The primary difference is form factor and typical application. Cork sheet from Kaxite Sealing is a rigid, flat panel material ideal for gaskets, insulation boards, and precision cutting. Cork roll is a thinner, more flexible material often used as underlayment for flooring or as a protective wrap. Our KAX-FLEX grade bridges this gap, offering a fabric-backed flexible cork sheet for specific sealing needs.
Q: Do you offer custom fabrication or die-cutting services?
A: Absolutely. Kaxite Sealing provides comprehensive custom fabrication services. We can precision die-cut your cork sheet into any 2D shape, including complex gaskets with multiple holes and contours, based on your CAD drawings or samples. This saves you time, reduces material waste, and guarantees a perfect fit for your assembly line or project requirements. Contact our sales team with your specifications for a quote.
Q: How does the thermal insulation performance of cork compare to foam or fiberglass?
A: Cork sheet offers exceptional thermal insulation due to its closed-cell structure filled with gaseous compartments. With a thermal conductivity (k-value) ranging from 0.038 to 0.050 W/m·K, it performs comparably to many rigid foam boards and significantly better than standard fiberglass batts. Additionally, cork provides superior acoustic damping, compressibility for sealing, and structural integrity that many foam products lack, making it a versatile, multi-functional insulation material.
