Physical and chemical properties:    
Appearance: brilliant yellow powder
Color: fluorescent white
Intensity: ≥100%(compared to standard substances)
Solvation: non-water-solubility
Moisture: ≤0.5%

Performance and features: 
1. Intense fluorescence and high brightness
2. Good thermal stability, not decomposed even above 330oC
3. A small quantity, usually only 100∼300ppm(0.01∼0.03%)

Application scope:
Widely used in brightening the fusion filature of polyester staple fiber as well as plastics

Usage mode:
1. Although the recommended quantity is 100∼300ppm (0.01∼0.03%), it can be added or reduced adequately according to the brightness of the raw material and the requirements of the consumers. The consumers themselves can add dulling agents or purple blue dyestuff (together with whitening agent) as well
2. The key point is to make the fluorescent whitening agents mix with the raw material smoothly so that whitening asymmetry can be avoided
3. Specific craftwork will be improved accordingly after your sample test

Packing and storage: 
Packed in 2kg x 5 paper boxes at cool and dry places to be protected from light
