Non-Asbestos Sheets are high-performance engineered sealing and insulation sheets manufactured without the use of asbestos fibers. Instead, they are produced using a combination of aramid fibers, synthetic fibers, cellulose fibers, high-grade fillers, and elastomeric binders (such as NBR, SBR, EPDM or other rubbers). These sheets are processed under high pressure and controlled temperature, resulting in a dense, uniform, chemically stable material suitable for high-temperature and high-pressure applications.

Non-asbestos sheets are widely used for gaskets, flange joints, pipeline sealing, chemical industry sealing points, compressors, valves, boilers, pumps, and general industrial equipment. They are designed to replace hazardous asbestos-based materials while offering equal or superior performance in sealing, temperature resistance, mechanical strength, and chemical compatibility.

Non Asbestos Gasket Sheet is a high-performance sealing sheet manufactured from a blend of aramid fibers, mineral fibers, synthetic fibers, fillers, and high-grade elastomers (NBR/SBR/EPDM). These sheets are engineered to replace traditional asbestos sheets, offering superior sealing performance, enhanced safety, and environmental compliance.

Using advanced calendaring and vulcanization processes, non-asbestos sheets achieve excellent compressibility, recovery, tensile strength, and resistance to heat, pressure, and chemicals. They maintain structural integrity even under fluctuating operating conditions, making them suitable for a wide range of industrial applications.

The sheets are available in various grades—general purpose, oil-resistant, steam-resistant, high-temperature, and acid-resistant—depending on the elastomer binder and fiber composition.

Gasket Sheets are versatile, high-performance sealing materials designed for creating custom gaskets in a wide range of industrial applications. They are manufactured from synthetic fibers, mineral fillers, elastomeric binders, and specialty polymers, depending on the required performance characteristics. Gasket sheets provide excellent compressibility, resilience, chemical resistance, and thermal stability, ensuring a tight, leak-proof seal between flanged connections, pumps, valves, and other equipment.

These sheets are available in multiple types, including non-asbestos, rubber, PTFE, graphite, and composite grades, making them suitable for use in industries such as chemical, petrochemical, oil & gas, power plants, food processing, and general manufacturing.

Non Asbestos Jointing Sheet is a high-performance sealing material engineered from a blend of aramid fibers, mineral fibers, synthetic fibers, fillers, and high-quality elastomer binders such as NBR, SBR, or EPDM. Designed as a safe and efficient replacement for asbestos-based sheets, it delivers excellent mechanical strength, thermal stability, and chemical resistance across a wide range of industrial sealing applications.
