Гибкая графитовый лист и Roll (расширения Гра

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. As a leading manufacturer,we can offer the lower-sulphur flexible graphite sheets/rolls, non-sulphur flexible graphite sheets/rolls. And we are the sole producer from China who can manufacture the nuclear grade flexible graphite sheets/rolls. For more details,please feel free to contact with us.
