European and American countries generally offer ASBESTOS FREE GASKET or NON ASBESTOS GASKET is 100% FREE of ASBESTOS gaskets.Asbestos-free gasket or asbestos-free gasket, but in the Chinese market some companies will contain a certain amount of asbestos (5-20%) gasket is called non-asbestos gasket, and 100% asbestos-free gasket is called asbestos-free gasket.In view of this special situation, we hereby reiterate that all gaskets operated by our company are asbestos-free gaskets which do not contain any asbestos.Unless there are special circumstances but will elaborate.

CAF: asbestos rubber sheet CFS: non-asbestos rubber sheet
1）Can a non-asbestos gasket be used instead of the conventional asbestos rubber gasket?
Generally, it is difficult to find such asbestos-free gaskets, because common CAF not only has high temperature resistance and chemical resistance, etc., while CFS, namely rubber fiber board, is mainly aramid butadiene rubber board with high oil resistance.But the anti - corrosion needs to use the polytetrafluoroethylene material, the high temperature industrial ore majority USES the graphite material.

2）Why is CFS more brittle and brittle than CAF?

The fiber content in CFS is low and the filler content is high, while the fiber content of CAF is generally 70-80% to maintain good tensile strength.

3）What should we pay attention to when choosing CFS?

Choose reliable and reputable manufacturers; 
Should consider temperature, pressure, medium and flange and bolt, nut and other conditions.

4）Can you provide 4MM or 5MM CFS?

Due to the material properties of CFS itself, we do not recommend the use of more than 3MM plate but can provide 4MM
