OBA Optical Brightener OB-1Powder Description:
Optical brightener powder, also known as fluorescent brightener. Commonly known as white fluorescent dyes, an organic compound, its characteristic is that it can make incident light produce fluorescence, make the dyed material obtain fluorescence effect, and make the material seen by the eyes white.. Many products,especially recycle material has yellow hue, add optical brightener OB-1 powder is using the principle which blue and yellow are complementary colors, when optical brighteners emit blue color,it can make up the yellow hue to make products seem more white and bright.

Polyamide is commonly known as nylon in English name Polyamide (referred to as PA), with a density of 1.15g/cm3. It is a general term for thermoplastic resins containing repeating amide groups—[NHCO]—on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. family pa. Among them, aliphatic PA has many varieties, large output and wide application, and its name is determined by the specific number of carbon atoms of the synthetic monomer.
It was invented by the famous American chemist Carothers and his research group. Nylon is a term for polyamide fiber (nylon), which can be made into long or short fibers. Nylon is the trade name of polyamide fiber, also known as Nylon. The English name Polyamide (referred to as PA), its basic composition is an aliphatic polyamide connected by amide bonds—[NHCO]—.
