Trigonox® C is a monofunctional peroxide used for crosslinking natural and synthetic rubbers, as well as thermoplastic polyolefins. It features good thermal stability and is effective in enhancing the crosslinking of polymers such as synthetic rubbers, natural rubbers (NR), and thermoplastic polyolefins (TPO). This liquid peroxide, chemically identified as tert-Butyl peroxybenzoate, is widely regulated and compliant with chemical inventories across various regions, including Taiwan (TCSI), Korea (KECI), China (IECSC), New Zealand (NZIoC), Japan (ENCS), the Philippines (PICCS), Canada (DSL), Japan (ISHL), Australia (AICS), and the USA (TSCA).

Application Information
  • Trigonox C is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins.
  • Rubber compounds containing Trigonox C have moderate processing safety in combination with a very high rate of cure.
  • Safe processing temperature (rheometer ts2 > 20 minutes): 100°C
  • Typical crosslink temperature (rheometer t90 about 12 minutes): 140°C
  • Trigonox C is not recommended for compounds which contain carbon black.

Technical Details & Test Data

Thermal stability
  • Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self- accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.
  • For Trigonox C SADT : 60°C (140°F)

Packaging & Availability

Packaging Information
  • In North America Trigonox C is packed in non-returnable, one gallon polyethylene containers of 8 lb net weight (packed 4 per case) and 5 gallon polyethylene containers of 40 lb net weight.
  • In other regions the standard packaging is a 30-liter HDPE can (Nourytainer®) for 25 kg peroxide.
  • Both packaging and transport meet the international regulations. For the availability of other packed quantities contact your AkzoNobel representative.
  • Trigonox C is classified as Organic peroxide type C; liquid; Division 5.2; UN 3103.

Storage & Handling

Storage Information
  • Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, AkzoNobel recommends a maximum storage temperature (Ts max.) for each organic peroxide product.
  • Ts max. = 25°C (77°F) and
    Ts min. = 10°C (50°F) to prevent crystallization
