  • Optical Brightener PF-3

    Optical Brightener PF-3

    Fluorescent brightener PF-3 can be dissolved with plasticizer and then milled into a suspension with three rolls to form a mother liquor. Then stir in the PF-3 plastic fluorescent whitening agent suspension uniformly during the processing, and shape it at a certain temperature (the time depends on the temperature), generally at 120150℃ for about 30 minutes, and 180190℃ for about 1 minute. 



    The fluorescent whitening agent KSNp not only has excellent high temperature resistance, but also has good resistance to sunlight and weather. The fluorescent whitening agent KSN is also suitable for the whitening of polyamide, polyacrylonitrile and other polymer fibers; it can also be used in film, injection molding and extrusion molding materials. The fluorescent whitening agent is added at any processing stage of synthetic polymers. KSN has a good whitening effect.
