Sinophor® FP-127 is a good plastic fluorescent whitening agent, which can be used to whiten and brighten polymers, coatings, printing inks and synthetic fibers. It has the characteristics of high whiteness, good shade, good color fastness, heat resistance, weather resistance, and non-yellowing. It can be added to the monomer or prepolymerized material before or during polymerization, polycondensation or addition polymerization, or added in the form of powder or pellets before or during the molding of plastics and synthetic fibers. This variety is suitable for all kinds of plastic varieties, but it is especially suitable for whitening and brightening of artificial leather products and the whitening of PVC of sports shoe soles.
