| Use Characteristics: |
A super accelerator HiDispersion® TMTD-80 used as secondary accelerator for NR, SBR, NBR, IIR, BR, and CR. When used together with delayed action accelerators such as CBS and others, HiDispersion® TMTD-80 acts as an activator. It is an activator for basic accelerator, e.g. aldehyde amine and guanidine, and suitable for low temperature curing products. As a sulfurless cuirng agent, It gives good heat resistance and aging resistance. If mercapto or sulphenamide accelerators are added, the vulcanization undergoes retardation. In such cases they have little effect on the degree of crosslinking; they mainly reduce the scorch rate and increase total curing time. |
| 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 TMTD is assured. |
