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.

Fluorescent brightener OB is a very compatible brightener, suitable for most plastic products, with a melting point of about 200℃. Compared with the fluorescent whitening agent FP-127, its whiteness is slightly worse, but the weather resistance is very good. In addition to being suitable for ordinary plastics such as PP, PET, PS, ABS, HDPE, LDPE, PVC, etc., it can also be used in the PE film, coating, and paint and ink industries.

With a population of more than 200 million, Indonesia is the most populous country in Southeast Asia. The main ports for importing waste plastics are Jakarta, Surabaya, and Batam; the total import volume of waste materials in 2019 is about 600,000 tons.

Jakarta and Surabaya: mainly imported PP, PC, PVC, ABS to meet domestic demand. PE waste is used in the production of packaging bags, containers, and tarpaulins for rain protection.

ABS produces luggage and helmets, PP waste is used to produce woven bags and cement bags, there are large feed factories and cement plants in the local area, and PVC waste production pipelines.

Batam: Waste imports account for about half of Indonesia's total imports, mainly imported PE waste film processed into pellets and sent to the Chinese market.

According to data from the Indonesian Ministry of Industry, so far, there are a total of 925 plastics companies producing a variety of plastic products. This field has absorbed 37,327 employees, with a total output of 4.68 million tons.

The plastic packaging industry and even the downstream chemical industry have the fastest growth and have huge potential.

It is not difficult to see from our export data that the export volume of optical brighteners in Indonesia is also huge.
