The product is made of quality flake graphite,the expansion, repression, and other technology is made resistant to high temperature, corrosion resistance,aging,self-lubricating, compressibility, elasticity,and other fine sealing performance,the flexible graphite mat film,the ideal packing material.It is to creat the basis for all kinds of graphite sealing materials. You can customize special specifications according to customer demand.
