Coal coke asphalt

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 300400?.

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: ? 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??/?



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