Is the fiber sealing gasket plastic?

Fiber sealing gaskets are not plastic products. Fiber sealing gaskets are usually made of fiber materials, such as aluminum silicate fiber paper, which has excellent high temperature resistance, low thermal conductivity, thermal shock resistance and high temperature insulation performance. Aluminum silicate fiber paper is made of loose cotton as the main raw material, and a very small amount of inorganic or organic binder is added. It is refined through a wet forming process. It can maintain structural stability in high temperature environments, is not easy to deform or damage, and ensures the durability of the sealing effect. In addition, fiber sealing gaskets are also non-toxic, harmless and environmentally friendly. They are suitable for various equipment and pipelines in high temperature environments, such as high temperature sealing of heating equipment flanges in petrochemical, metallurgical, electric power and other industries.
