Application Note Technical Fundamentals of UV Laser Marking of Silicone

Silicone is used in many demanding applications due to its material properties. At the same time, the material poses unique challenges for laser marking. Low absorption, high elasticity, and sensitivity to heat input make it difficult to achieve stable and reproducible laser marking results. This application note explains the material-related challenges and demonstrates how silicone can be marked reliably and gently using UV-based laser technology.
