Fluorescent brighteners are mainly used to remove yellowing and whitening of recycled plastics. Below we mainly introduce the characteristics and uses of the two best-selling fluorescent brighteners in the Indonesian market.
Fluorescent Brightener OB-1 393
The main feature is the high melting point, which can reach 360℃ degrees Celsius, which is a good choice for the production of high temperature products.
The fluorescent whitening agent OB-1 has two appearance colors, green and yellow. The whitening effect is the same except that the shade of yellow OB-1 is a little purple. But for customers who produce color masterbatches, the yellow-green appearance of the fluorescent whitening agent OB-1 directly affects the appearance color of the particles, so be careful when choosing.
The optical brightener OB-1 is widely used in PP, PET, PS, ABS, HDPE, LDPE, PVC, PBT etc plastics industry. In addition, the optical brightener OB-1 is also widely used in polyester staple fiber and color masterbatch.
