Coal Tar Pitch (CTP) | Basetrade Global

Coal is carbonized in a reducing atmosphere and the off-gas is collected and sent to the by-product plant where coke oven gas and subsequently coal tars are gathered. Coal Tar Pitch is a solid at room temperature, exhibiting a broad softening range instead of a defined melting temperature.
