Product Description:

Properties and Usage:

Optical brightener OB-1 belongs to the bisbenzoxazole type of the six major categories in the industry. Optical brightener is considered a white dye and is often used in the textile industry. Because fluorescent whitening agents can absorb part of invisible ultraviolet light and have the characteristics of reflecting visible light, they can play a great role in whitening items and are widely accepted by the plastic products industry. Adding it to materials such as PVC and PE can effectively prevent products from producing yellow-like visible light that is not easily accepted in the industry, and produce a bright and white beautification effect, which has a good effect on increasing product selling points. Coupled with its good thermal stability, it can appropriately save the use of other heat stabilizers.

Among the original whitening methods, the blue method was the most commonly used method. Although this method can effectively reduce other visible light, the product will appear dull. FSCI-OB-1 can make up for this shortcoming. The blue light of the product can effectively compensate for the wavelength of light that causes the product to be dull, making the product more white.
