Luperox® A75 industrial grade benzoyl peroxide is a 75% active grade of BPO with remainder water added for added safety. This water-wet powder is available in every region of the world, with or without residual surfactant. Traditional uses like general purpose, high-impact, or expandable polystrenes depend on benzoyl peroxide powders for bulk polymerizations. Room temperature curing operations such as thermoset or acrylic composites can be achieved using heavy metal or amine accelerators. Arkema's packages come in a range of net weights to assist with accurate dosing. Luperox® A75 is the fastest half-life organic peroxide available worldwide that does not require temperature control.
