Application
Polymerization of Ethylene – DTBP is an effective initiator for the production of low density polyethylene. Both the kettle method under high pressure and the kettle method under high pressure tube are applicable. In actual production, in order to obtain a wide polymerization temperature range, it is often used in combination with other peroxides.
