Optical Brightener OB-1 Description
What is Optical Brightener OB-1?
Optical Brightener OB-1 is an excellent diphenylethylene bisbenzoxazole type compound. It is odorless, hard to dissolve in water and has stable capability. And it also has good resistance to heat, sunlight, chlorine bleaching and migration. It has an ideal whitening effect on polyester fibers as well as polyester fiber-containing fabrics including polyester-cotton blend fabric.
Optical Brightener OB-1 can absorb invisible ultraviolet light (with a wavelength range of approximately 360-380nm) and convert it into longer wavelength blue or purple visible light, thus compensating for unwanted slight yellow in the matrix. At the same time, they reflect more visible light than the original incident wavelength in the range of 400-600nm, making the product appear whiter, brighter, and more vibrant.
It can be used to whiten various kinds of plastics such as ABS, PS, HIPS, PA, PC, PP, EVA and rigid PVC. With addition of optical agent OB-1, polyamide fiber,nylon and polyester have significantly good whiteness. Mixed with this product, recycling polyester waste material, bottle material and slice flake will have a higher whiteness than before. It can be used for whitening polyesters, nylon fibre and various plastics.

Optical Brightener OB-1 Applications
Plastic whitening:
Suitable for whitening plastics such as ABS, PS, HIPS, PA, PC, PP, EVA, hard PVC, etc., especially suitable for high-temperature molding processing scenarios (such as hot melt dyeing). The addition amount is 0.01% -0.05% of the material weight, and it needs to be mixed evenly before forming and processing.
Textile whitening:
The whitening effect on polyester fibers, nylon, and blended fabrics of polyester and other fibers (such as cotton) is significant, which can improve the consistency of whiteness and chromaticity. Simultaneously applicable for whitening treatment of polyester raw materials.
Recycling material processing:
Whitening for recycling polyester fiber waste, bottle materials, and chips can improve the appearance quality and color consistency of recycled materials.
