Modified Medium-Temperature Coal Tar Pitch
Package: In bulk when do domestic transportation for the purpose of saving costs, and packaged in polypropylene PP jumbo bags for exports.
Uses : It can be used as binder pitch for the production of high-power graphite electrodes( mainly used in steel mills and other metal smelting ), aluminum with anode paste and prebaked anode adhesives ( mainly for the aluminum plant ), carbon black and carbon
Usage : It is obtained by distilling soft pitch in modifier under certain pressure and temperature after certain time of heating.
Product description: Physical and chemical properties Coal tar pitch is a black solid consist of fused ring aromatic hydrocarbons and macromolecular resin, at a certain temperature, it will be solidified into a brittle solid with shell-like fracture. It will melt in a certain range of melting points, but it has no definite melting point. Coal tar pitch has no thermal effect when solidified. Its flash point is 204.4°C , and its boiling point is no higher than 470°C . Melting point is between 100-200°C. Density is around 1.25-1.35g/cm3.
