Kaxite is a trusted global leader in the manufacturing and supply of industrial-grade sealing and insulation materials. With decades of specialized engineering experience, we have perfected the formulation and production of superior Non-asbestos Sheets that meet the most demanding applications across diverse sectors. Our commitment to innovation, quality control, and customer safety is embedded in every product we ship worldwide.
A Non-asbestos Sheet is an advanced engineered material designed to replace traditional asbestos-based gaskets and insulation. Asbestos, once widely used for its heat resistance and durability, is now a prohibited substance due to its severe health hazards. Kaxite's Non-asbestos Sheets provide all the necessary mechanical and thermal properties—such as high tensile strength, excellent compressibility, and resistance to fluids and temperatures—without any of the associated health risks. They are fabricated using a sophisticated blend of organic and inorganic fibers, binders, and fillers like aramid, glass, cellulose, and nitrile rubber, resulting in a safe, reliable, and high-performance material.
Kaxite offers a comprehensive range of Non-asbestos Sheet materials. Each grade is developed with a specific set of properties to address unique operational challenges. Below are the detailed parameters for our flagship grades.

What exactly is a Non-asbestos Sheet made from?
Kaxite Non-asbestos Sheets are composite materials engineered from a carefully selected blend of synthetic fibers (such as aramid and glass fibers), organic fibers (like cellulose), elastomeric binders (e.g., nitrile or SBR rubber), and mineral fillers. This combination is processed under high pressure and temperature to create a homogeneous, strong, and flexible sheet with properties tailored to replace asbestos.
How do I select the right grade of Non-asbestos Sheet for my application?
Selection depends on three primary factors: the fluid/media being sealed, the operating temperature and pressure, and the flange type/surface finish. For hot water or steam up to 290°C, our KX-7100 is often suitable. For higher temperatures or more aggressive alkalis, KX-7200 is recommended. For applications involving oils, fuels, or a wide range of chemicals, the KX-7300 grade offers superior resistance. Our technical team can provide detailed selection guidance based on your specific parameters.
Are Non-asbestos Sheets as durable and heat-resistant as old asbestos sheets?
Yes, modern high-quality Non-asbestos Sheets like those from Kaxite meet or exceed the performance of traditional asbestos materials in most applications. While pure asbestos had very high intrinsic temperature resistance, our engineered composites achieve excellent thermal stability (up to 400°C continuous for some grades) combined with better compressibility, recovery, and chemical resistance, resulting in a more reliable and safer seal overall.
What are the key standards and certifications for Non-asbestos Sheets?
Reputable Non-asbestos Sheets comply with various international standards. Kaxite products are tested and certified to meet or exceed specifications such as ASTM F104, ASTM F1315, DIN 3754, and JIS B 3453. They are also compliant with global environmental and safety directives like REACH and are manufactured in ISO 9001 certified facilities, ensuring consistent quality.
Can I machine and cut Kaxite Non-asbestos Sheets easily?
Absolutely. One of the practical advantages of our sheets is their ease of fabrication. They can be cleanly cut with utility knives, scissors, or die-cut for simple shapes. For complex gaskets, they can be punched, laser-cut, or waterjet-cut precisely. Always use sharp tools and cut on a clean, hard surface for the best results.
How should I store Non-asbestos Sheets to ensure their longevity?
Store the sheets in a cool, dry, and dark environment away from direct sunlight, heat sources, and moisture. Ideal storage temperature is between 10°C and 25°C (50°F - 77°F). Keep the sheets flat and horizontal to prevent curling or deformation. Store them in their original packaging until use to avoid contamination from dust or oils.
What is the typical lead time for ordering custom sizes or grades?
Kaxite maintains a substantial inventory of standard grades and sizes for quick dispatch. For custom-calendered thicknesses, special formulations, or large-volume projects, our standard lead time ranges from 2 to 5 weeks depending on complexity. We prioritize communication and provide accurate timelines with every order inquiry.
