The whitening of plastic is to uniformly mix the optical brightener into the pre-molding material before compression molding. In order to whiten the plastic evenly, the following two points are very important. Pure quality optical brighteners are generally suggested to be added to polymers. They can be added before or during polymerization, or before high-temperature molding. When brightening light-colored plastic products,most of them are
