Perkacit MBT is a moderately fast curing primary accelerator for natural and synthetic rubbers.
- In NR compounds, Perkacit MBT based vulcanization systems exhibit less reversion upon overcure
than other systems.
- Its low activation energy makes compounds rather scorchy, particularly in furnace black reinforced compounds. Compound scorch behavior can be improved by replacing Perkacit MBT with Perkacit MBTS.
- Vulcanizates obtained with Perkacit MBT tend to have a relatively low modulus, but very good aging properties.
- To achieve a faster cure and a higher modulus, Perkacit MBT can be boosted by the use of
secondary accelerators, such as Perkacit ZBEC, Perkacit ZDEC, Perkacit TBzTD, Perkacit TMTD or
Perkacit DPG.
- For the vulcanization of EPDM or IIR rubbers, Perkacit MBT is a well established component of many existing vulcanization systems.
- Perkacit MBT also finds application in latex foam cure systems.
- The product is non-staining and non-discoloring.
- Perkacit MBT is regulated for use in articles in contact with food as specified under FDA 21 CFR 177.2600, 175.105, 176.300 and under BgVV XXI, Categories 1-4 and "Sonderkategorie". |
