SUKANO^® Optical Brighteners offer a color management system for transparent applications to correct/neutralize the yellowish color shade seen in recycled materials and biobased polymers. In addition, they clear up the entire appearance of the product.

SUKANO^® Optical Brighteners are often used in combination with SUKANO^® UV Masterbatches to neutralize the yellowish shade of the UV additive e.g. in cap layers as well to determine the layer thickness of the UV protected cap layers.
