Coal Tar Pitch

Name:
Coal Tar Pitch
Detailed information:
Dark-brown to black amorphous residue left after coal tar is redistilled. It is composed almost entirely of polynuclear aromatic compounds and constitutes 48–65% of the usual grades of coal tar. Different grades have different softening points: roofing pitch softens at 65C, electrode pitch at 110–115C. Combustible.

Hazard:

Volatile components (anthracene, phenanthrene, acridine) are carcinogens. TLV: 0.2 mg/m3.

Use:

Binder for carbon electrodes, base for paints and coatings. Impregnation of fiber pipe for electrical conduits and drainage, foundry core compounds, briquetting coal, tar-bonded refractory brick, paving and roofing, plasticizers for elastomers and polymers, extenders, saturants, impregnants, sealants.
