SWCNT Slurry – High-Conductivity Single-Walled Carbon Nanotube Dispersion for ESD Plastics, Coatings and Battery Materials

SWCNT slurry is a high-conductivity, pre-dispersed formulation of single-walled carbon nanotubes. It provides fast, uniform dispersion in plastics, coatings and battery materials, enabling ultra-low loading, stable resistivity and clean processing in water, NMP or ethanol.

Introduction

Our SWCNT slurry is formulated using high-aspect-ratio single-walled carbon nanotubes (eDIPS process). Through proprietary dispersion technology, the CNT network remains stable and uniform in water, NMP, ethanol and mixed systems. It is designed for ESD plastics, conductive coatings, printed electronics and battery electrode additives.

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. 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.

Kela Material presents Cerium Orange - One of the Cerium-Based Inorganic Pigment Series The main component of Kela cerium-based inorganic pigments is cerium sulfide. Cerium sulfide (Ce₂S₃) has a chemical composition approximating Ce₂S₃ and forms orthorhombic crystals. It is insoluble in water and strong alkaline solutions but readily dissolves in acids, releasing hydrogen sulfide gas. Under inert gas and reducing atmospheres, it maintains chemical stability up to 1500°C, while in oxidizing atmospheres it remains stable up to 350°C. Color Range and Properties The Kela Cerium Red cerium-based inorganic pigment series covers a color spectrum from deep red to orange-yellow. Cerium Red is a soft crystalline phase material that does not damage the structure of glass fibers in plastics and can actually enhance the mechanical properties of glass fibers. Key Advantages Non-toxic: Safe for use and complies with EU export standards and related national safety, health, and environmental regulations Strong covering power: Excellent opacity and color strength Good thermal stability: Maintains performance at high temperatures Environmentally friendly: Serves as an excellent substitute for toxic cadmium sulfide-based or heavy metal-based inorganic pigments Applications As a new type of green, environmentally friendly pigment, Cerium Red's high temperature resistance makes it widely applicable in: Plastics industry Rubber industry Other applications requiring heat-resistant, non-toxic colorants This innovative pigment represents a significant advancement in replacing traditional toxic heavy metal pigments while maintaining superior performance characteristics and meeting stringent international safety standards.

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.
