Asbestos sheet

Asbestos Gasket Sheet is also known as Asbestos Sheet, Compressed Asbestos Fiber Jointing Sheet, CAF Gasket Sheet, Asbestos Jointing Sheet, and Paronite.Asbestos rubber sheet is made from asbestos fiber, natural rubber and inorganic heat-resistant filling materials, etc., rolled by professional production equipment. It is mainly used as sealing material for pipe flanges, high pressure vessel flanges and various mechanical connection surfaces. It can be divided into high pressure, medium pressure, low pressure asbestos rubber sheet and other types according to the formula, process, performance and use, is currently the most economical sealing gasket material.

Application field
Asbestos rubber sheet is widely used in the field of pipeline and equipment sealing in petroleum, chemical, electric power, metallurgy, shipbuilding, construction and other industries. It can be used to seal the pipe flange connection of water, steam, air, ammonia lye and other media, and can also be used for high temperature and high pressure water, saturated steam, gas, inert gas and other media of equipment pipe flange connection sealing gasket material..
