Scope

1.1 This classification covers the compounding material known as ground coal. It is generally used in rubber compounds as a filler.

1.2 There are three grades of ground coal based on particle size, ash, and moisture. The selected values for these properties are suitable for use in a rubber compound.

Significance and Use

Ground coal is commonly used as an inexpensive filler in rubber compounds as a direct or partial replacement for carbon black or as a diluent in the compound.

Ground coal is very compatible with most rubbers and is very easily mixed into the compound.
