What exactly is a non-asbestos sheet made from?
Kaxite non-asbestos sheets are composite materials engineered from a carefully selected blend of organic and inorganic synthetic fibers (such as aramid, glass, or cellulose), fillers (like carbon, rubber, or mineral powders), and elastomeric binders (like NBR, SBR, or acrylic). This formulation is calendared or processed under heat and pressure to create a homogeneous, strong, and flexible sheet material that replicates or surpasses the performance of historical asbestos-based products.
Are non-asbestos sheets completely safe?
Yes, when sourced from a reputable manufacturer like Kaxite. Our sheets are rigorously tested and certified to contain no detectable asbestos fibers. They eliminate the risks of asbestosis, lung cancer, and mesothelioma associated with asbestos. However, standard industrial safety practices should always be followed during fabrication (e.g., dust control, ventilation) as a precaution against inhalation of any particulate matter.
How does the performance compare to traditional compressed asbestos fiber (CAF) sheets?
Modern high-quality non-asbestos sheets like Kaxite's KX-7200 grade often outperform traditional CAF sheets. They offer comparable or superior sealing capability, better consistency in material properties, higher tensile strength, and improved resistance to creep relaxation. The key advantage is achieving this performance without any health hazards, making them the only legal and responsible choice in most countries.
What are the primary applications for Kaxite non-asbestos sheets?
Our sheets are versatile and used across industries as gasketing, sealing, and insulation materials. Common applications include: gaskets for flanges in pipelines, pumps, and compressors in oil & gas and chemical plants; heat shields and insulation in automotive and aerospace; gland packing in valves; and as a general-purpose sealing material in power generation, marine, and heavy machinery.
How do I select the right grade of non-asbestos sheet for my application?
Selection depends on the service conditions. Consider the media (steam, oil, chemical, water), temperature range, pressure (PSI/Bar), flange type, and required compliance standards. KX-7100 is excellent for general industrial use with water, steam, and oils up to 290°C. KX-7200 is designed for more severe services with higher temperatures and pressures, and offers broader chemical resistance. Our technical team can provide specific recommendations.
Can Kaxite non-asbestos sheets be used for high-pressure steam applications?
Absolutely. Grades like our KX-7200 are specifically engineered for high-pressure steam service. Their low creep relaxation and high recovery ensure the gasket maintains a tight seal under thermal cycling and high bolt pressure, preventing steam leakage. Always verify the specific pressure-temperature rating for the grade and thickness you select.
How are non-asbestos sheets fabricated and installed?
They can be easily cut with utility knives, die-cut, punched, or laser-cut. For gasket creation, it's crucial to use sharp tools and proper compression during bolt-up. Follow standard gasket installation procedures: ensure flange surfaces are clean and undamaged, align the gasket properly, and use a calibrated torque wrench to tighten bolts in a star pattern to the recommended torque value to ensure even compression and optimal sealing.
Do non-asbestos sheets have any storage or shelf-life limitations?
Kaxite sheets should be stored in a cool, dry place away from direct sunlight, extreme temperatures, and moisture. They should be kept flat to prevent warping. When stored under these recommended conditions, our sheets have a shelf life of over 5 years without significant degradation of properties. Avoid contact with solvents or ozone-generating equipment during storage.
Are Kaxite non-asbestos sheets certified?
Yes. Kaxite products are tested and certified to meet major international standards. Our certifications include ISO 9001:2015 for quality management, and our materials are compliant with directives such as REACH and are manufactured according to ASTM, DIN, and JIS testing standards. Specific certification documents are available upon request for customer audits and quality assurance processes.
Can you produce custom formulations or sizes?
Kaxite specializes in developing customized solutions. We can work with clients to develop special formulations for unique chemical exposures, extreme temperatures, or specific color/identification needs. Custom sheet sizes, thicknesses, and die-cut gaskets are also part of our service offering for large-volume projects.
