What exactly is a non-asbestos sheet?
A non-asbestos sheet is a high-performance industrial sealing and insulation material manufactured without any asbestos fibers. It is engineered from a composite of safe synthetic fibers (such as aramid or cellulose), mineral fillers, and rubber binders. Its primary function is to create a reliable, compressible seal between mating surfaces in equipment like flanges, engines, and pipelines, capable of withstanding high temperature, pressure, and chemical exposure.
How does Kaxite non-asbestos sheet compare to traditional compressed asbestos fiber (CAF) sheets?
Kaxite non-asbestos sheets match or exceed the technical performance of traditional CAF sheets in key areas like temperature resistance, sealing ability, and tensile strength. The critical difference is safety. Our sheets contain no carcinogenic asbestos, protecting worker health and eliminating liability issues. They also often offer better consistency, batch-to-batch uniformity, and improved recovery properties, leading to longer gasket life and reduced maintenance downtime.
For which applications are Kaxite non-asbestos sheets most suitable?
Our sheets are versatile and used across industries. Common applications include: gaskets for pipe flanges, pumps, and valves in chemical plants; cylinder head gaskets, exhaust manifold gaskets, and heat shields in automotive and marine engines; seals in boilers, turbines, and heat exchangers in power generation; and insulation layers in high-temperature industrial equipment. The specific grade (NA-100, NA-200, etc.) should be selected based on the operating pressure, temperature, and media.
How do I select the correct thickness and grade for my application?
Selection depends on several factors: flange surface condition, bolt load, internal pressure, and fluid type. For standard ANSI flanges, 1.5mm thickness is common. Rougher surfaces may require thicker sheets (2.0mm-3.0mm). For high-pressure applications, use the reinforced NA-200 grade. Consult Kaxite's technical datasheets or contact our engineering support with your operating conditions (max temperature, pressure, medium) for a precise recommendation to ensure optimal performance and safety.
What are the best practices for fabricating gaskets from Kaxite sheets?
Use sharp, clean cutting tools—knives, clicker presses, or CNC cutters—for clean edges. Ensure the sheet is clean and dry before cutting. The gasket should be cut to match the flange face exactly, covering the entire sealing area. Boltholes should be punched, not drilled, to prevent fraying. Always follow the recommended torque sequence and values when installing the gasket to achieve even compression and an effective seal. Avoid over-tightening, which can damage the sheet fibers.
Are Kaxite non-asbestos sheets certified or compliant with international standards?
Yes. Kaxite non-asbestos sheets are tested and compliant with major international standards, including ASTM F1315 (Standard Specification for Non-Asbestos Fiber) and meet the requirements of DIN, JIS, and BS standards. They are also compliant with environmental and safety regulations such as REACH and RoHS. Specific grades like our NA-400 hold FDA approval for incidental food contact. Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS) are available for all products.
How should I store and handle these sheets to maintain their quality?
Store sheets in a cool, dry, and flat environment away from direct sunlight, excessive heat, and moisture. Keep them in their original packaging until use to prevent contamination. Stack sheets horizontally to avoid bending or warping. Handle with clean gloves to prevent oil or dirt from skin contaminating the sealing surface. Sheets have a long shelf life when stored correctly, typically over 5 years from the date of manufacture.
Can Kaxite produce custom-formulated sheets for a unique application?
Absolutely. Kaxite's strength lies in our custom engineering capabilities. If your project involves extreme temperatures, unique chemical exposures, or requires specific conductivity/resistivity properties, our R&D team can develop a tailored non-asbestos sheet formulation. We work directly with clients to prototype and test materials, ensuring a perfect fit for challenging or proprietary applications.
