German Standard Non-Asbestos Gasket Sheet
High-Temperature & Pressure Sealing Solution for Pipe Flanges and Fluid Systems
H1 – Product Introduction
This German-standard non-asbestos gasket sheet is engineered for reliable sealing in industrial piping, flange connections, and fluid transfer systems. Developed using high-strength synthetic fibers combined with elastomeric binders, the material delivers dependable performance under thermal load, mechanical stress, and chemical exposure—without the use of asbestos.
Designed to meet modern environmental and export compliance requirements, this gasket material is suitable for long-term service in water, oil, fuel, steam, and gas systems where operational safety and sealing stability are essential.
H2 – Core Performance Benefits
-
Fully asbestos-free formulation aligned with EU and international regulations
-
Consistent sealing capability under fluctuating temperature and pressure
-
Strong resistance to oils, fuels, steam, and industrial media
-
Reduced stress relaxation to maintain bolt load over time
-
Easy to cut, punch, or fabricate for OEM production and field maintenance
