Electronic and hybrid polymer systems place far stricter demands on laser marking than conventional plastics. Requirements such as electrical neutrality, material purity, dimensional stability, and long-term reliability significantly narrow the acceptable processing window. This article explains the unique challenges of laser marking in electronic and hybrid polymer systems, why many standard marking approaches fail, and what fundamental material behaviors must be considered to achieve reliable and compliant marking performance.

Low-power and high-speed laser marking is increasingly adopted to improve throughput, reduce thermal damage, and enable finer feature resolution. However, many conventional laser marking additives fail under these conditions. This article explains why standard additives designed for high-energy marking lose effectiveness at low laser power and high scanning speeds, and which fundamental material limitations drive these failures.

Antimony-based laser marking additives have long been used to enhance laser absorption and contrast in plastics. However, increasing regulatory pressure, purity requirements, and application-specific constraints are driving growing demand for antimony-free laser marking solutions. This article explains when antimony-free laser marking matters, why antimony-containing systems become limiting in modern polymer applications, and how alternative laser-responsive mechanisms enable compliant and stable marking performance without relying on antimony.

Background

Laser marking on plastics can be broadly divided into two categories: black laser marking and colored laser marking. While black marking remains the most widely adopted ...

Detail

Carbon black is widely used for laser marking due to its strong laser absorption. However, in modern polymer systems it often causes uncontrolled conductivity, poor edge definition, migration, and regulatory risks. This article explains the structural failure modes of carbon black in laser marking plastics and why controlled laser-responsive inorganic additives are increasingly preferred.

Laser marking additives—often referred to as “laser marking pigments”—frequently fail due to mismatches between material mechanism, substrate behavior, and laser conditions. This article benchmarks common failure modes in laser marking systems and explains why certain additives fail, how to diagnose the cause, and which functional alternatives perform better.

Detail

LaserMark additives (often searched as laser marking pigments) are laser-responsive functional additives designed to generate durable, high-readability contrast on plastics. This decision tree helps engineers and designers select the appropriate LaserMark grade based on substrate color, absorption behavior, marking mechanism, and application requirements.

Laser marking performance depends on more than optical absorption. This article explains why some laser marking additives fail despite strong absorption at laser wavelengths. It highlights the importance of energy conversion efficiency, thermal response, and compatibility with polymer matrices in laser marking applications.
