CTPI is used as an inhibitor of premature vulcanization of synthetic and natural rubbers, providing the rubber compounder with a better means of controlling scorch safety. CTPI is most effective with thiazole and sulphenamide accelerator systems and the fastest curing polymers. An approximate order of response by polymer is: NR > NBR > SBR > EPDM > IIR > CR. CTPI increases processing safety without affecting vulcanizate properties, aged properties, fatigue life, stain, discoloration, or porosity. Typical loading levels are 0.1 to 0.4 phr.
