Expanding the Potential of High-Performance Materials Through Proprietary Dispersion Technology

Leveraging its long-standing, proprietary ultra-fine particle dispersion technology, Mitsubishi Pencil provides high-quality dispersions of materials that are otherwise difficult to disperse—such as PTFE (fluororesin), carbon nanotubes (CNTs), and graphene.

Furthermore, for CNTs and graphene, we offer custom dispersion services: we can mix these materials with specific resins or inorganic substances as requested by each individual client to create tailored dispersions.

PTFE Dispersions

Our PTFE dispersions are liquid materials in which PTFE—a substance traditionally difficult to disperse uniformly in organic solvents—is stably dispersed at the nanoscale.

These dispersions can be easily incorporated into resins or varnishes and integrated seamlessly into existing manufacturing processes.

They leverage the inherent properties of PTFE—such as low dielectric constant, excellent water and oil repellency, and low friction—to enhance electrical characteristics, improve sliding performance, and increase wear resistance.

They are well-suited for a wide range of applications, including high-frequency circuit boards, low-dielectric resins, functional coatings, molding materials, and binders for high-performance batteries.

CNT and Graphene Dispersions

While CNTs and graphene possess excellent electrical conductivity, they are prone to aggregation, making them difficult to handle.

Leveraging our proprietary dispersion technology and mass-production expertise, we provide these materials as uniform and stable dispersions.

Our products achieve an optimal balance of high solid content, low viscosity, and low moisture content, providing robust support for the development of next-generation battery materials—from slurry preparation to electrode coating.

By maximizing the performance of these conductive additives, we enhance contact efficiency with active materials, simultaneously improving battery performance and increasing the efficiency of manufacturing processes.
