Expandable Graphite for Flame Retardant

Name of Commerdity:

Expandable graphite Expandable, Sulfur Free, Low Sulfur. Fixed carbon: 98%min; Expansion: 200 Size: +80, mesh
Expandable graphite is a graphite intercalation compound (GIC).
Usage: Expandable graphite was mainly used as an intermediate. Since 1990's, expandable graphite has been used by more and more amount as fire barrier material and flame retardants. Now expandable graphite had been used in PU foam. Expandable graphite had been found its application in intumescent flame retarded coatings. Expandable graphite had already been used in PE, PP and other POs when halogenated flame retardant was forbidden use. Recently expandable graphite had been used in bitumen roof sheets. In other applications like fire-stop putties, fire-stop pillows, expandable graphite had replaced other intumescent agents and used widely.

Property: The expandable graphite is a kind of high-ranking sealing material. With features of heatproof, abrasive resistance, anticorrosion, oxidation resistance, great surfactivity and strong adsorbability, it is a replacement for traditional sealing materials such as asbestos, rubber and some metallic materials in making various sealing parts in pump, valve, pressure vessel and pipelines.
