Expandable Flake Graphite Asbury Carbons

Expandable Flake Graphite. Expandable Flake Graphite Intercalation: Expandable flake graphite, also known as intumescent flake graphite, or simply “expandable flake”, is a form of intercalated graphite. Intercalation is a process whereby an intercallant material is inserted between the graphene layers of a graphite crystal or particle.

Jan 01, 2002 This may be correlated with the presence of the expandable graphite. The graphite contributes to the solid phase in the intumescent shield and consequently leads to a loss of the elasticity of the material. It results in a comparative decrease in tan δ.

Permanent mold casting

Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal.The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings.Common casting metals are aluminium, magnesium, and copper alloys.

The heat release rate of the PU foam was decreased with increasing EG content (up to an 83 % decrease at an 18 wt% EG content). This is a relatively slower rate than that of the conventional PU foams. This may be attributed to the fact that EG may be expanded, and as such, there is a higher chance of hindering the oxygen and heat flow at an
