Frequently Asked Questions (FAQ) About Non-Asbestos Gaskets
Q: What exactly are non-asbestos gaskets made from?
A: Non-asbestos gaskets are composite materials engineered using safe, synthetic fibers as the primary reinforcement. The most common fiber is aramid (e.g., Kevlar®-type), known for its high strength and thermal resistance. These fibers are embedded in a binder matrix, which can be various synthetic rubbers (like NBR, SBR, CR, or FKM) or sometimes elastomeric polymers. The blend is completed with mineral fillers (e.g., clay, silica, carbon) and other additives to achieve specific properties like compressibility, chemical resistance, and temperature tolerance. Kaxite formulations are proprietary, optimized for balanced performance.
Q: Are non-asbestos gaskets as durable and effective as the old asbestos ones?
A: Yes, modern high-quality non-asbestos gaskets like those from Kaxite are not only as effective but often superior. While asbestos had natural heat resistance, it was prone to embrittlement and required high bolt loads to seal. Our advanced composites offer excellent thermal stability, better compressibility and recovery (leading to longer seal life under cycling conditions), and superior chemical resistance to a broader range of media. They provide a more reliable and predictable sealing performance while being completely safe to handle and cut.
Q: How do I select the right Kaxite grade for my application?
A: Selection depends on three critical service parameters: Media, Temperature, and Pressure. First, identify the fluid or gas being sealed and consult our chemical resistance chart. Second, determine the continuous and peak operating temperatures of your flange. Third, know the system pressure. Match these to our grade specifications table. For example, use KAX-900HT for high-temperature steam, KAX-850FS for concentrated acids, and KAX-600CR for refrigerant lines. Our technical support team can assist with complex or borderline applications.
Q: Can I use non-asbestos gaskets in existing flanges designed for asbestos gaskets?
A: In the vast majority of cases, yes, directly. Kaxite non-asbestos gaskets are designed as drop-in replacements. They generally require similar or slightly lower bolt torque values due to their better compressibility. It is, however, crucial to ensure the flange faces are in good condition (clean, parallel, with proper surface finish) and to follow recommended torque sequences and values provided in our installation guide to achieve an optimal seal.
Q: How do I store and handle Kaxite non-asbestos gasket sheets?
A: Store sheets or finished gaskets in a cool, dry place away from direct sunlight, ozone sources (like electric motors), and extreme temperatures. Keep them flat to avoid warping or bending. Sheets should be stored on a flat shelf, not leaned against a wall. While our materials are robust, avoid dragging them over sharp edges to prevent surface scoring. Always wear appropriate personal protective equipment like gloves and safety glasses when cutting or trimming gaskets.
Q: Do you offer custom shapes, sizes, or material formulations?
A: Absolutely. Kaxite specializes in providing tailored sealing solutions. We can die-cut, water-jet cut, or laser-cut gaskets to any precise 2D shape from our standard sheet stock. We also offer custom calendering for specific thicknesses and can develop proprietary material formulations for unique applications involving extreme temperatures, pressures, or highly corrosive media.
