1 of 2 products in this brand
Optical Brightener OB-1 is a high molecular weight fluorescent whitening agent, which significantly improves the whiteness in both textile fibers and plastics. Brightener OB-1 produces very brilliant white with light reddish Blue effect which compensate for yellowing. It has good light fastness. Because of its exceptional whitening properties, excellent resistance to heat, low volatility and easy dispersibility, Optical Brightener OB-1 is now widely used in plastic market. It has good compatibility in various substrates; in combination with dyes, it produces bright shades. Brightener OB-1 is used in polymer fibers especially polyester and polyamide fibers. It is also widely used in PP, ABS, PS, HIPS, PA, PC, EVA, Rigid PVC etc.
