IFI Technical Production company locates in China and is a leading developer of graphite deposits and processing of graphite materials. The main specialization and activity - the development and production of advanced sealing and gasket materials.We produce Packings of expanded graphite, PTFE, aramid fibers, carbon fibers and other synthetic and natural fibers. Our products have over 15 years of successfully delivered to Europe, America, Australia, Russia, etc.It is one of the biggest enterprises of the mineral, chosen the mineral and deep processed in whole from China. our products, flexible graphite sheet, flexible graphite roll are widely used in the fields of petroleum & chemical industry, refining, electric power, metallurgy, machinery, papermaking, automobile, shipping building, pharmacy, aerospace industry, nuclear industry, etc. Rely on advanced technology and management system, superior production equipments and test instruments, high quality products and first-class service. The products, flexible graphite sheet, flexible graphite roll, lower-sulphur graphite, non-sulphur graphite, high quality graphite, lower-sulphur graphites, non-sulphur graphites, high quality graphites enjoy the high reputation in domestic and abroad market, and it has been exported to more than 20 countries and regions.
| Flexible graphite sheet & roll,namely expanded graphite sheet & roll, is made from flake graphite with high carbon content which is gone through chemical treatment, expanding under high temperature and then rolling. It has the characteristics of high temperature resistance, corrosion resistance and good elasticity, and is the basic material for making all kinds of reinforced graphite sheets, graphite tapes, packing and sealing gaskets. |
