has launched a new series of laser marking additives that are said to have exceptional transparency without compromising the optical properties of the product. Moreover, they are compatible with a wide range of polymers and exclude chemicals that raise regulatory concerns, such as antimony.

These additives are also said to  perform well in plastics containing fillers such as calcium carbonate, talc, titanium dioxide or carbon black, and to achieve higher marking accuracy, requiring only a minimal dosage of a few percent, which represents a negligible increase in the raw material cost. They enable dark marking on both transparent and opaque backgrounds, light marking on dark backgrounds, grayscale marking and cost-effective black marking on transparent gray backgrounds. Tosaf offers customizable options for these additives to cater to specific client requirements. Additionally, they can be obtained as Combi Batch along with other additives like UV stabilizers and colorants.

Because of its inherent advantages, laser marking technology is particularly well suited for various external applications such as pipes, pipe accessories, profiles and irrigation products. These marking additives are approved for food contact applications, including bar code marking on beverage caps and marking expiration dates or batch numbers on transparent food packaging.
