FIELD: rubber industry and construction.
SUBSTANCE: invention is dealing with making unshaped rubber plates for crushing-mediated manufacture of colored granulate. Curable rubber compound is prepared from rubber (100 wt parts), crushed cured stock (5-40 wt parts), and urethane fluoropolymer with molecular weight 1000-5000 and terminal isocyanate group level 2.5-6 wt % (0.5-4.0 wt parts).
EFFECT: reduced cure time and increased resistance of cured product against ageing.
