Coal Tar Pitch is a kind of black solid of density 1.25-1.35g/cm3, when it heated to a high certain temperature, it will become soft status. Accoding to different softening point, it can be divided to low temperature pitch, middle teperature pitch and high temperature.

The technical parameters of middle temperature pitch:

Softerning point: 75-95       105-115

Toluene: 15-25%                 28-34

Quinoline: 6-15%                 8-14

B-Rosin: min                         17-26

Coking value: min

Ash: <0.3%

Moisture: <5%                        0.3
