Style 6300 (R P W E) Flexible graphite is manufactured from 100% pure graphite flakes, which are treated and processed without resins, binders, or other additives that would limit corrosion resistance and high temperature applications. Style 6300 is permanently resilient, non-hardening, naturally lubricious (requires no flange release agent), and has an infinite shelf life. Flexible graphite has seal of approval of companies throughout the world involved in the manufacture and handling of corrosive, volatile or flammable liquids. Recommended Uses Makes an ideal gasket for high temperature applications to 850°F in non-oxidizing atmospheres, and is resistant to attack by most molten metals, hot corrosive chemicals and caustics.
