In industrial sealing, safety, reliability, and compliance are non-negotiable. For decades, the dangers of asbestos have driven the global shift towards safer, high-performance alternatives. Non-asbestos gaskets have emerged as the superior choice, offering exceptional sealing capabilities without the associated health risks. At Kaxite Sealing, we specialize in engineering premium non-asbestos sealing materials designed to meet the most demanding applications across diverse industries. This guide provides a comprehensive look at our products, their technical specifications, and their critical role in modern operations.
Non-asbestos gaskets are sealing components manufactured from safe, synthetic fibers reinforced with high-quality elastomers and fillers. These materials are engineered to replicate and often exceed the thermal, chemical, and pressure resistance of traditional asbestos-based gaskets. Kaxite Sealing utilizes advanced aramid fibers (such as Kevlar®), glass fibers, carbon fibers, and mineral fibers, bound together with nitrile rubber (NBR), styrene-butadiene rubber (SBR), or other specialized polymers to create sheets of consistent quality and performance.
Kaxite Sealing offers a range of non-asbestos gasket materials categorized by their reinforcement fiber and binder system. Below are detailed specifications for our core product lines.

Q: Are non-asbestos gaskets as durable and effective as the old asbestos gaskets?
A: Absolutely. Modern non-asbestos materials from reputable manufacturers like Kaxite Sealing are engineered to meet or exceed the performance of traditional asbestos gaskets in most industrial applications. Advancements in fiber technology and compound formulations provide excellent thermal stability, creep resistance, and sealability. For extreme conditions, specific high-performance grades (like our KAX-NA4100) are available that outperform asbestos in chemical resistance and pressure handling.
Q: How do I select the correct non-asbestos gasket material for my specific application?
A: Selection is based on the operating conditions of your system. The key factors to consider are: 1) Media: Identify the fluid (oil, steam, acid, fuel, water). Check our chemical resistance charts. 2) Temperature: Consider both continuous operating temperature and any peak temperatures. 3) Pressure: Determine the maximum internal pressure or vacuum level. 4) Flange Type & Condition: Consider the flange material, surface finish, and bolt load. Kaxite Sealing provides detailed technical datasheets and expert engineering support to guide your selection process.
Q: What industries commonly use Kaxite Sealing non-asbestos gaskets?
A: Our products are trusted across a vast range of industries, including Oil & Gas (pipeline flanges, pumps, valves), Chemical & Petrochemical (reactors, heat exchangers), Power Generation (steam turbines, boilers), Marine & Shipbuilding (engine systems, piping), Water Treatment, Pharmaceutical, Food & Beverage (where FDA-compliant grades are used), and General Manufacturing & HVAC systems.
Q: Can you supply custom-cut gaskets, or do you only sell sheets?
A: Kaxite Sealing offers maximum flexibility. We supply standard sheets and rolls for in-house fabrication. More importantly, we operate a state-of-the-art die-cutting and CNC machining facility to produce precision custom gaskets to your exact drawings and specifications. This ensures perfect fit, reduces installation time, and minimizes material waste for our customers.
Q: What are the storage and handling recommendations for non-asbestos gasket sheets?
A: To maintain optimal performance, store materials in a cool, dry place away from direct sunlight, extreme temperatures, and ozone sources (like electric motors). Keep sheets flat and avoid bending or creasing. Stack sheets horizontally to prevent deformation. Always handle with clean hands or gloves to avoid contaminating the sealing surface with oils or dirt before installation.
Q: How does Kaxite Sealing ensure the quality and consistency of its non-asbestos materials?
A: Quality is the cornerstone of our manufacturing process at Kaxite Sealing. We implement rigorous quality control from raw material inspection to final product testing. Every batch is tested against international standards (ASTM, DIN, ISO) for critical properties like density, tensile strength, compressibility, and recovery. Our commitment to consistent formulation and production ensures you receive a reliable, high-performance gasket every time.
