Compressed Non-asbestos Fibre sheets are manufactured using high-performance fibers, rubber, and inorganic fillers as main raw materials, through processes such as mixing, calendaring or sheet forming, and high-temperature vulcanization. They are widely used for flange sealing applications and offer good resistance to oil, heat, aging, and mild chemical media, serving as an environmentally friendly alternative to traditional asbestos-based materials.
