Coal coke asphalt (modified asphalt)
Coal coke asphalt is the residue in the deep processing of coal tar. It is a
black solid or semi-solid material obtained by coal tar distillation
(300~400℃).
Coal coke asphalt, a premium-grade carbonaceous material derived from coal tar
distillation (300-400℃), serves as a critical component in multiple industrial
applications. This black semi-solid material contains high concentrations of
polycyclic aromatic hydrocarbons (PAHs), granting exceptional bonding strength,
thermal stability, and chemical resistance properties.

Superior Adhesion: β resin content ≥18% ensures optimal binding capacity for
electrode manufacturing and refractory materials
High Coking Value: ≥50% coking yield forms durable carbon matrices under
extreme temperatures
Chemical Resistance: Withstands acid, alkali, and organic solvent exposure in
harsh industrial environments
Temperature Adaptability: Adjustable softening point range (60-180℃) for
specialized applications

Primary Utilization Areas:
Aluminum Production: As the principal binder in cathode paste formulations for
electrolytic cells operating at 950-1000℃

Graphite Electrodes: Essential bonding agent for ultra-high power (UHP)
electrode production, demonstrating 12-15% lower electrical resistivity than
standard binders

Waterproofing Systems: Core component in coal tar-based membrane systems (ASTM
D2626/D2626M standard) with 98% water impermeability

Advanced Material Processing:
Needle Coke Production: High-quality feedstock for premium-grade needle coke
with CTE values below 1.0×10⁻⁶/℃

Carbon Fiber Precursors: Modified coal coke asphalt yields carbon fibers with
tensile strength exceeding 3.5 GPa
