High-Quality Non-asbestos Sheet Manufacturers and Wholesale Solutions

What is a Non-asbestos Sheet?

A non-asbestos sheet is a high-performance sealing material engineered to replace traditional asbestos-based gaskets. Asbestos, once prized for its heat resistance and durability, is now known to pose severe health risks, leading to its ban in many countries. Modern non-asbestos sheets, such as those manufactured by Kaxite Seals, are composed of advanced synthetic fibers like aramid, glass, carbon, or cellulose, bound together with high-quality elastomers and fillers. These materials are carefully formulated to match or exceed the mechanical and thermal properties of asbestos without any associated health hazards. They are the industry-standard solution for creating reliable, leak-proof seals in a vast array of demanding applications, from industrial pipelines and chemical processing to automotive engines and marine equipment.

Frequently Asked Questions (FAQ)

General Questions

What exactly does "non-asbestos" mean?
"Non-asbestos" means the material is completely free from asbestos fibers. It is manufactured using safer, modern synthetic or organic fibers like aramid (e.g., Kevlar®), glass, carbon, or cellulose. These fibers are combined with rubber binders (like NBR, SBR) and fillers to create a sealing sheet that performs similarly to—and often better than—old asbestos-based materials without the cancer risk.

Are non-asbestos sheets as good as the old asbestos sheets?
Yes, modern high-quality non-asbestos sheets from reputable manufacturers like Kaxite Seals are superior in many ways. While matching the temperature and pressure resistance, they often offer better consistency, improved chemical resistance for specific fluids, and greater flexibility. Most importantly, they provide this performance while being completely safe to handle, cut, and install.

How do I choose the right non-asbestos sheet for my application?
Selection depends on three primary factors: the fluid/media being sealed, the operating temperature, and the system pressure. First, check the chemical resistance chart for the media. Then, ensure the sheet's temperature range covers both normal and peak operating temps. Finally, verify the pressure rating. Kaxite Seals provides detailed specification tables and technical support to guide this selection process.

Installation & Handling

How do I cut and fabricate a gasket from a non-asbestos sheet?
Sheets can be easily cut with a sharp utility knife, scalpel, or scissors for simpler shapes. For production or complex shapes, die-cutting, water-jet cutting, or CNC milling is used. Always cut on a clean, flat surface. Use the flange as a template or a precise CAD drawing. Ensure the cut is clean and the gasket is the exact size of the flange face—it should not overhang into the bore nor be too small.

What is the proper bolt tightening procedure for a non-asbestos gasket?
Correct bolt loading is critical. Always follow a cross-pattern torque sequence (star pattern). Tighten bolts in several passes (e.g., 30%, 60%, 100% of final torque) to ensure even compression across the entire flange. Use a calibrated torque wrench. Refer to the manufacturer's recommended seating stress or follow standard flange assembly guidelines (like ASME PCC-1). Avoid over-torquing, which can crush the gasket and cause failure.

Can I reuse a non-asbestos gasket?
It is strongly not recommended. Non-asbestos sheets are designed to compress and conform to the flange surfaces during the first installation to create a seal. Once compressed and heat-cycled, the material's recovery properties are partially used. Reusing an old gasket significantly increases the risk of a leak. Always install a new, clean gasket for a reliable seal.

Performance & Safety

What chemicals can non-asbestos sheets resist?
Resistance varies by formulation. Kaxite Seals' standard grade (KAX-NAS 1000) handles water, steam, air, and mild chemicals. Our oil-resistant grade (2000) is for fuels and hydrocarbons. The chemical-resistant grade (4000) with PTFE handles strong acids and alkalis. Always consult the specific chemical compatibility guide for the sheet grade against your exact service media.

What is the maximum temperature a non-asbestos sheet can handle?
This varies greatly. Standard grades typically handle up to 200°C-250°C (392°F-482°F). Specialized grades like Kaxite's KAX-NAS 3000, reinforced with glass fiber and graphite, can withstand continuous service up to 550°C (1022°F) for steam and hot air applications. Always select a grade where the maximum continuous temperature exceeds your application's peak operating temperature.

Are Kaxite Seals non-asbestos sheets certified?
Yes. Kaxite Seals products are manufactured under strict quality control systems (ISO 9001 certified). Our materials are tested to meet or exceed international standards such as ASTM F104, DIN 3750, and JIS B 2403. Material Safety Data Sheets (MSDS) are provided, confirming the absence of asbestos and any other restricted substances, ensuring full regulatory compliance for safe handling and use.

Purchasing & Brand

Why should I choose Kaxite Seals over other brands?
Kaxite Seals combines decades of material science expertise with rigorous manufacturing standards.

What sizes and forms are available?
Kaxite Seals non-asbestos sheets are typically supplied in full sheets (e.g., 1500mm x 1500mm or 48" x 48"), rolls (for specific thin grades), and pre-cut gasket kits for common flange sizes. Standard thicknesses range from 0.5mm (1/64") to 6.0mm (1/4"). Custom sizes and die-cut gaskets can be produced to customer drawings for high-volume requirements.

How do I store non-asbestos sheet material?
Store in a cool, dry, and dark place away from direct sunlight, heat sources, ozone generators (like motors), and chemicals. Keep the sheets flat and avoid bending or creasing them. Store away from sharp objects. Proper storage prevents premature aging, drying out, or deformation of the material, ensuring optimal performance when used.
