NAME ACCORDING TO TU: Pitch «Pirol».

Produced according to TU 2214-386-05742686-2003.

A product of cationic (block-) coolygomerization of unlimited hydrocarbons in the structure of С8-С10 – fractions of pyrolysis of petrochemical products and their mixtures with other unlimited hydrocarbons, including termocoolygomers of unlimited hydrocarbons С8-С10. Marks 1 and 4 are solutions of a pitch in nefras or in other non-toxic hydrocarbons. 2 and 3 are marks of solid pitch in the form of granules or pieces. Mark 1 is used as a component of drying oil “Oxcol” and alkyd varnishes, accelerating their drying and improving their physicomechanical parameters Is used in manufacture of technical rubber products, constructing materials and road coverings. Mark 3 - as a component of moulding constructional materials in mechanical engineering. Mark 4 - for manufacturing chemically, atmospheric-and waterproof anticorrosive coverings.
