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 tube high pressure are applicable. In actual production, in order to obtain a wide range of polymerization temperature, it is often used in combination with other peroxides.
