The products made of asbestos are rejected step-by-step when people demanding more and more on the health and environment-protection. Expandable teflon and flexible graphite are used much more widely than ever in modern industry. Although they are gradually replace the asbestos gasket, they cannot do it completely because they have some defect. So the non-compressed asbestos sheet become the best replacement of asbestos material. The non-asbestos sheet which is made of aramid fiber, inorganic fiber, synthetic rubber etc under high temperature and high pressure. The non-asbestos material is widely used in the joint part of tubing, valve, heat exchanger, pressure container in refinery, chemical plant, power plant, boatyard, pipework.
