Expandable graphite is a flexible graphite product obtained through special modification treatment from high-quality natural flake graphite produced by our company. It is an ideal new type of sealing material and is widely used in dynamic and static sealing in industries such as petroleum, chemical engineering, power, aviation, automobiles, ships and instruments and meters.
Expandable graphite, after high-temperature instantaneous treatment, turns from flaky to worm-like, and its volume can expand by 100 to 400 times. This expandable graphite still retains the properties of natural graphite and has excellent formability, flexibility, ductility and sealing performance. It is an excellent raw material for various graphite plates and sealing parts, and can also be used as a new type of protective slag and heating agent in the metallurgical industry.
Specifications : 9950250 9980250 9950200 9980200 9550250 9580200 etc.
