APC series	brightening in white paper pulp and brightening during coating	Good affinity to fibers, good acid resistance as well as calcium cation and magnesium cation  resistance, a kind of commonly used fluorescent brightening agent, good compatibility with other papermaking chemicals, little interference to the wet end of paper machine with high-degree white water  blocking, environment protectional with low COD in white water.
APB-L series	brightening in white water pulp, especially applicable to the brightening of secondary fiber white paper and newsprint paper.	Good affinity to fibers, little interference to the wet end system of paper machine, more applicable to the brightening of the system with neutral sizing and comparatively low white water blocking degree.
APH	sizing brightening and coating brightening on high-white paper surface	Best brightening ability, excellent acid resistance ability, small binding force with fibers, can only be superficially added, smaller PCD comparing to the like products.
VBL series	brightening in white paper pulp	Excellent affinity to fibers, more applicable to the brightening of the system with neutral sizing and comparatively low white water blocking degree.
CXT/CPD	brightening of textile fabrics during printing and dyeing as well as washing	Comparatively good affinity to cotton fibers and synthetic fibers, good weak acid resistance, perborates resistance, and hydrogen peroxide resistance, applicable to one-bath oxygen bleach brightening and hot tie-dyeing brightening.
CBS-X	brightening of textile fabrics during printing and dyeing as well as washing	High-efficient brightening ability to textile fabrics, chlorine beach tolerance, oxygen bleach tolerance as well as strong acid and strong alkali resistance, washing fastness, and strong binding force to textile fabrics.
