High-Purity Impregnation Pitch

Physical and Chemical Specification: Softening Point: 85-90oC ，Ash≤ 500ppm, Coking Value: ≥48%, Toluene Insoluble: ≥18%, Quinoline Insoluble: ≤0.5%

Application Area: It is mainly used for impregnating for big format high power and ultra high power graphite electrode, to increase density and decrease resistivity, in addition it can also used for impregnating for carbon/carbon composite and carbon fibre, used as the high quality pitch raw material for needle coke and general grad carbon fibre production.
