The FP-127 is an optical brightener applicable to polymers, especially for PVC and PE products. It brings blue fluorescence in polymers. The bright white color will present on the products if used low concentration of FP-127 together with anatase titanium dioxide type A. The concentration of FP-127 should add-up if the rutile titanium dioxide type R will be used. It is also widely used in other thermoplastics, e.g. PMMA, cellulose carbonate, etc.
