Description and features

Enox BPO 75W (Dibenzoyl Peroxide 75%) is a white particle moistened with 25% water. This diacyl peroxide, with the chemical formula C14H10O4, not only serves as an initiator for the (co)polymerization of styrene, acrylonitrile, acrylates, methacrylates, and vinyl acetate, but it also enhances the overall efficiency of these processes. Additionally, its versatility makes it a valuable component in a wide range of polymer formulations. Furthermore, its effectiveness in initiating these processes makes it a valuable component in various polymer formulations. Additionally, it is used to cure unsaturated polyester, vinyl ester, and acrylic thermosetting resins at ambient temperatures.

Known as benzoyl peroxide, BPO, and benzoperoxide, Dibenzoyl peroxide offers versatile applications in various polymer processes.
