Laser marking pigments are added to plastics and inks and irradiated with YAG lasers to achieve high-contrast and fine printing. The pigment particles absorb the laser energy, causing the resin surrounding the pigment to turns white. This results in a laser marking pigment characterized by high blackness and fine (transparent) printing, requiring only minimal addition regardless of resin type or substrate shape. The laser marking market continues to grow due to its advantages, including ink-free systems, scratch resistance, versatility in surface design, anti-tampering and anti-counterfeiting properties, and high-quality, high-speed marking. Unfortunately, many common polymers are difficult to mark effectively because of insufficient absorption of the laser beam. Laser marking pigments developed by Kela provide excellent marking performance on various plastics and coatings at very low loading levels.

The material is a complex vanadate of copper, zinc, and vanadium.


Zirconium Phosphotungstate (ZWP) is a negative thermal expansion material with good chemical, thermal, and high-temperature mechanical stability. It exhibits significant negative thermal expansion characteristics over a wide temperature range (25-800°C) and has no phase change or water absorption in this negative thermal expansion temperature range.

Zr2 SP2 O12 is the world's first material with two different contraction mechanisms: a framework mechanism and a phase transition mechanism.

Bismuth Nickel Iron Oxide Chemical Formula: z-BiNi1-xFexO3

arbon nanotubes are seamless nanoscale tubular structures formed by single or multiple layers of graphene rolled up along a central axis at a certain helical angle.Single-Walled Carbon Nanotubes: Fewer amorphous carbon, metal, and other impurities and defects, high electrical conductivity.

MXene is a general term for complex atomic layer compounds composed of early transition metals (such as titanium, vanadium) and light elements (carbon or nitrogen), with a layered structure similar to graphene. The surface of the sheets has various polar functional groups, which gives them high dispersibility in hydrophilic materials.

Conductive paste is manufactured by dispersing single-walled carbon nanotubes prepared by the eDIPS method. Through unique dispersion technology, dispersion in water, NMP, and ethanol is achieved while maintaining a high aspect ratio.

MXene is a general term for complex atomic layer compounds composed of early transition metals (such as titanium, vanadium) and light elements (carbon or nitrogen), with a layered structure similar to graphene.

Graphene is an allotrope of carbon, where carbon atoms are sp² hybridized to form a single-layer hexagonal honeycomb lattice.

Overview: Bi₂S₃ is used to replace Germanium (Ge) to form a new type of solid electrolyte Li₁₀BiₓP₂S₁₂₋ₓ. The traditional LGPS solid electrolyte (e.g., Li₁₀GeP₂S₁₂) has excellent ion conductivity, but the high cost and scarcity of Ge limit its large-scale application. By introducing urchin-like Bi₂S₃, it not only provides high capacity potential in terms of structure but also effectively buffers volume and thermal expansion problems during cycling.

Single-walled carbon nanotubes (SWCNTs) are seamless, nanometre-scale tubes formed when one or several graphene sheets roll around a central axis at a defined helical angle. Thanks to exceptionally low levels of amorphous carbon, metal residues and structural defects, they deliver outstanding electrical performance.

Laser marking pigments are added to plastics and inks and irradiated with YAG lasers to achieve high-contrast and fine printing. The pigment particles absorb the laser energy, causing the resin surrounding the pigment to carbonize, while the marking pigment itself turns black. This results in a laser marking pigment characterized by high blackness and fine (transparent) printing, requiring only minimal addition regardless of resin type or substrate shape. The laser marking market continues to grow due to its advantages, including ink-free systems, scratch resistance, versatility in surface design, anti-tampering and anti-counterfeiting properties, and high-quality, high-speed marking.
