Carbon black is a finely dispersed amorphous carbon material produced by combustion or thermal decomposition of gas and liquid hydrocarbons.

Resins are natural or synthetic elastomers, feedstock for rubber and ebonite production. The major part of the total resin produce is processed into rubber. Rubber is highly elastic and formable, compression and abrasion resistant, gas- and waterproof, chemically stable, non-conductive; it has low density and high heat stability.
