Use Characteristics A super accelerator Konson® TMTM-80 causes very rapid and scorch-safe vulcanization of natural and synthetic rubbers. Konson® TMTM-80 receives additional activation from basis accelerators, e.g. aldehyde amine and guanidine.
Together with sulphenamide and mercapto accelerators in which Konson® TMTM-80 is used as secondary accelerator are of great technical importance. Low sulphur vulcanization provides vulcanizates with good ageing resistance.
Processing Advantages The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective TMTM is assured.
