PEPTON 22 is a peptiser for use in the high-temperature mastication of natural and synthetic rubbers.
PEPTON 22 is used in the high-temperature mastication of natural rubber, polyisoprene, SBR and nitrile rubbers where it is desired to increase the efficiency of breakdown.
Its use is usually restricted to internal mixers because of its high activation temperature. |
