ROWALID LS-Masterbatches

ROWALID®-LS type masterbatches make thermoplastic materials laser-markable.

The majority of thermoplastics cannot be marked economically sufficient without the addition of special laser additives. ROWALID®-LS masterbatches enable laser marking of thermoplastics. The special additives increase the absorption ability of the polymer matrix or change color themselves (intrinsic effect) and thus create a permanent change in color. A whitish/light grey marking is achieved by foaming, whereas carbonization or coloring of the additive results in a dark/dark grey marking. By combining special additives and colorants even colored markings can be achieved.
