TAC/GR 50 is a 50% and TAC/GR 70 a 70% triallycyanurate (TAC) in a granular form. TAC/GR granules are more stable and better applicable in automatic weighing machines than TAC/GR 70, whereas the latter contains a higher amount of active substance.

The difference between other coagents and TAC/GR is the higher reaction temperature which particularly gives better storage stability and improved scorch behavior (see also table 7) at processing temperatures. The compatibility of TAC/GR 50 and TAC/GR 70 with polymers is excellent, especially in EPDM, HNBR, CM and EVA.

The use of TAC/GR improves not only the general physical properties but also the temperature resistance of the cured rubber compound after heat aging. There will be no negative influence of the carrier of TAC/GR grades on the electrical properties of insulation compounds.
