TAPSTAR LM | LASER MARKING MASTERBATCH

The process during which components are labeled or marked with the aid of a laser is known as laser marking of plastic or plastic engraving. The method and the additive or grade used for laser marking depends on the polymer of the plastic component to be marked.

 

Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. Many plastics and thermoplastics can be laser marked. Should a plastic’s properties mean that it cannot be laser marked, it can usually be modified with a suitable additive or masterbatch for plastic laser marking.

TapStar LM series works on the basic mechanism where the active ingredient of our masterbatch absorbs the laser light and converts it into heat, decomposing the surrounding polymer to carbon, thus giving a high contrast black mark. Taprath also offers grades for white marks on black substrates. Here the mechanism changes. In this case, the laser light causes foam formation around the pigment, thus revealing the original colour of the base polymer which is typicallywhite or light yellow.

​

TapStar LM grades are compatible with PE, PP, PVC, PC, TPU and PA.
