Key Features
- Efficient initiator for high-pressure ethylene polymerization in autoclave and tubular processes
- Suitable for suspension polymerization of vinyl chloride in the 50-70°C range
- Can be combined with other peroxides to achieve a wider polymerization temperature spectrum
- Well-defined active oxygen content and low chloride impurity levels for consistent initiator performance
Main Applications of Trigonox 36-C75
For the polymerization of ethylene, Trigonox 36-C75 serves as an efficient initiator under high pressure in both autoclave and tubular processes; combinations with other peroxides are commonly applied in practice to obtain a wider spectrum of polymerization temperatures. For the polymerization of vinyl chloride, it is applied as an initiator for the suspension polymerization process in the temperature range of 50-70°C. It is also used for the (co)polymerization of vinylidene chloride and (meth)acrylates.
