Non-asbestos sheet is a high-performance industrial material engineered for applications requiring durability, fire resistance, and thermal insulation without the health hazards associated with traditional asbestos-based products. As global regulations have phased out asbestos due to its carcinogenic properties, non-asbestos alternatives have become the standard for safety-conscious industries worldwide. At Kaxite, we specialize in manufacturing premium-grade non-asbestos sheets that meet and exceed stringent international safety and performance standards. Our materials are the reliable choice for construction, automotive, marine, and industrial manufacturing sectors.
Non-asbestos sheet is a composite material formulated using a blend of synthetic fibers, reinforcing materials, and binding agents. Common fibers include aramid (e.g., Kevlar), glass fiber, cellulose, and carbon, bound with elastomers like NBR (Nitrile Butadiene Rubber) or SBR (Styrene-Butadiene Rubber). This composition provides excellent mechanical strength, heat resistance, and flexibility, mimicking the beneficial properties of asbestos without the associated health risks. Kaxite non-asbestos sheets are designed to perform reliably under stress, high temperatures, and corrosive environments.

Q: What exactly does "non-asbestos" mean? Is it completely safe?
A: "Non-asbestos" means the material contains 0% asbestos fibers. Traditional asbestos sheets used crystalline silicate fibers, which are proven carcinogens when inhaled. Kaxite non-asbestos sheets use modern synthetic or mineral fibers (like aramid, glass, cellulose) that pose no such health risks. They are completely safe to handle, machine, and install with standard workshop safety practices (wearing a dust mask during cutting is still recommended to avoid general particulate inhalation).
Q: How does the performance of non-asbestos sheet compare to traditional asbestos sheet?
A: Modern non-asbestos sheets like those from Kaxite often match or exceed the performance of legacy asbestos materials. They offer comparable or superior heat resistance, tensile strength, and sealing capability. Additionally, they provide better consistency, improved chemical resistance in many cases, and do not degrade or become brittle in the same way old asbestos products could. The key advantage is achieving this performance without any toxicological hazards.
Q: Can Kaxite non-asbestos sheets be used for high-pressure applications?
A: Yes, absolutely. Our sheets, particularly the KAX-NAS200 (Glass Fiber) and KAX-NAS400 (Carbon Fiber) series, are engineered with high tensile and compressive strength. They are suitable for static sealing in high-pressure flange connections in pipelines and pressure vessels. It is crucial to select the correct grade based on the operating pressure, temperature, and media, and to follow proper gasket design and installation procedures.
Q: Are these sheets resistant to all chemicals?
A> While Kaxite non-asbestos sheets exhibit excellent resistance to a wide range of chemicals—including oils, fuels, aliphatic hydrocarbons, steam, and alkalis—no single material is universal. Resistance can vary based on the fiber and binder composition. For example, our KAX-NAS400 series with fluoroelastomer binder offers superior resistance to aggressive acids, solvents, and aromatics. We always recommend consulting our technical datasheets or contacting our support team with details of the specific chemical media, concentration, and temperature for application suitability.
Q: How do I machine and fabricate parts from these sheets?
A: Kaxite sheets are designed for excellent machinability. They can be easily cut with utility knives, band saws, or laser cutters. For gaskets, they can be stamped, punched, or CNC die-cut. Drilling and routing are also straightforward. Using sharp tools is recommended to achieve clean edges. Standard workshop dust extraction or a simple dust mask is advised during machining to manage non-hazardous particulate matter. For water jet cutting, our sheets perform excellently without delamination.
Q: Do you provide custom sizes, shapes, or formulations?
A> Yes, Kaxite prides itself on flexible manufacturing capabilities. We can supply sheets in custom dimensions (width, length, thickness) outside our standard ranges. We also offer custom die-cutting and kiss-cutting services to deliver ready-to-install gaskets and parts. For projects with unique requirements—such as extreme temperature ranges, specific conductivity needs, or unusual chemical exposure—our R&D team can work on developing a tailored formulation.
Q: What certifications do Kaxite non-asbestos sheets hold?
A: Kaxite products are manufactured in facilities with strict quality management systems (ISO 9001 certified). Our materials are tested and certified to meet international standards such as ASTM, ISO, DIN, and JIS. They comply with major regulatory frameworks including the EU's REACH and RoHS directives, and are recognized as safe under OSHA guidelines. Specific fire safety certifications like UL 94 V-0 are standard across our product lines. Detailed certification documents are available upon request.
Q: How should I store non-asbestos sheets?
A: To maintain optimal performance, store Kaxite sheets in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and moisture. Keep them flat on a shelf or pallet to prevent bending or warping. Avoid contact with oils, solvents, or corrosive chemicals during storage. When stored correctly, our sheets have a long shelf life of several years without degradation of key properties.
