Fluorescent Brightener


Light yellow powder. Melting point of 230 ~ 232 ℃.

1. Fluorescence strong, high brightness.
2. Thermal stability, 330 ℃ high temperature does not decompose.
3. Use less, generally only 100 ~ 300ppm (0.01 ~ 0.03%).


Widely used in polyester staple fiber melt spinning whitening can also be used for plastic whitening.

1. ER general dosage is 100 ~ 300ppm (0.01 ~ 0.03%), according to raw material whiteness and customer requirements may be appropriate to increase or decrease, and the user can process requirements, add their own extinction agent or blue-violet dye and other ingredients.
2. The key is to completely make the fluorescent whitening agent and raw materials mixed evenly, so to prevent uneven whitening.
