In industrial sealing and high-temperature applications, managing heat and creating reliable barriers is paramount. Traditional asbestos materials, while effective, pose significant health risks due to the potential release of airborne fibers during handling, cutting, and installation. This is where modern, advanced dust free asbestos products come into play. Dust free asbestos refers to a new generation of engineered sealing materials that retain the excellent thermal insulation, fire resistance, and durability of classic asbestos but are manufactured using advanced processes and binders to eliminate the release of hazardous dust. Kaxite Sealing is at the forefront of this innovation, providing safe, high-performance solutions for demanding environments. Our products are designed to offer peace of mind without compromising on the technical performance required in industries such as petrochemical, power generation, foundry, and automotive manufacturing.
Kaxite Sealing offers a range of dust free asbestos products tailored for specific applications. Below are the detailed parameters for our flagship series, the KX-DFA ProLine.

Q: Is dust free asbestos truly safe and free from health hazards?
A: Yes, when referring to high-quality products like those from Kaxite Sealing. The term "dust free" indicates that the material is non-friable, meaning the fibers are locked within a matrix and will not become easily airborne during normal handling, cutting, or under mechanical stress. This significantly minimizes inhalation risk. However, as with all industrial materials, we recommend following good workshop practices, such as using local exhaust ventilation when machining and wearing standard PPE like safety glasses and gloves.
Q: How does the performance of dust free asbestos compare to traditional asbestos gaskets?
A: Kaxite Sealing's dust free asbestos is engineered to match or exceed the performance of traditional asbestos in key areas: temperature resistance, compressibility, and recovery. The advanced binders and fiber treatment often result in improved seal integrity over a wider temperature range and better resistance to creep relaxation under bolt load. The primary difference is the massively improved safety profile without sacrificing technical performance.
Q: Can I use Kaxite dust free asbestos for all the same applications as the old asbestos materials?
A: Absolutely. Our products are direct, safer replacements for traditional asbestos-based sealing and insulation. Common applications include: high-temperature flange gaskets, boiler and furnace seals, heat shield insulation, expansion joint packing, valve stem packing, and fireproofing seals in industrial ovens and kilns. Our technical team can advise on the specific grade (KX-DFA 1000, 1500, or 2000 HT) best suited for your operating conditions.
Q: What is the shelf life and how should I store this material?
A: Kaxite Sealing's dust free asbestos products have a shelf life of five years when stored properly. Store in a cool, dry, and well-ventilated area away from direct sunlight, excessive heat, and moisture. Keep the original packaging intact until use to prevent contamination and physical damage. Avoid stacking heavy objects on top of sheets or rolls to maintain their dimensional stability.
Q: Are there specific cutting or installation tools required?
A: No special tools are required. Standard gasket cutting tools—such as utility knives, scissors, hole punches, and die-cut presses—work perfectly. The dust-free property means you can fabricate gaskets on a standard workshop bench without generating hazardous dust clouds. For high-volume production, CNC cutting or clicker presses are ideal for precision and efficiency.
Q: Does Kaxite Sealing provide technical support and custom fabrication?
A: Yes. Kaxite Sealing prides itself on full-cycle customer support. Our engineering team can provide application analysis, material selection guidance, and CAD/CAM support for custom gasket design. We operate state-of-the-art fabrication facilities capable of producing custom sheets, precision-cut gaskets, molded parts, and complex composite seals to meet your exact specifications and drawings.
Q: How does this material comply with international regulations (like OSHA, REACH, etc.)?
A: Kaxite Sealing's manufacturing process and final products are developed with global regulatory compliance as a core principle. Our dust free asbestos is classified as an "article" under regulations like EU REACH, meaning it does not release hazardous fibers under intended use. It is designed to help users comply with occupational exposure limits set by OSHA and similar bodies worldwide. Detailed Material Safety Data Sheets (MSDS) and compliance certificates are available upon request.
Q: What are the disposal procedures for used or scrap dust free asbestos material?
A: While our product is safe during use, disposal regulations vary by region. Generally, scrap or used material should be treated as non-hazardous industrial waste in many jurisdictions due to its non-friable nature. However, we strongly advise consulting your local environmental agency or waste management provider for the most accurate and compliant disposal procedures. Always keep the material damp when bagging scrap to minimize any potential particulate release.
