Non-Asbestos Gasket Sheet

Product Description

Non-Asbestos Gasket Sheets are manufactured using aramid fiber, inorganic fillers, and high-quality rubber binders. They deliver outstanding sealing properties without the health risks associated with asbestos. These sheets are widely used for flange connections, pump housings, and machinery joints in industries such as petrochemical, power generation, shipbuilding, and automotive manufacturing.
