The Industrial Materials business group leverages core technological competencies to expand into diverse market segments. Our key technologies include Dispersion Technology, used in producing specialized inks for ballpoint and sign pens, and Sintering Technology, integral to our high-performance pencil and mechanical pencil leads. Additionally, we accumulate years of experience in Fine Machining and Container Design. We are proud to showcase our expertise in these fields.
Traditionally, ballpoint and marker pens relied on dyes for color. Mitsubishi Pencil, however, prioritized the superior durability of pigments, refining this technology over 40 years. While pigments are harder to process due to agglomeration and precipitation, Mitsubishi Pencil perfected its dispersion technology, now applied across various fields
Through developing advanced inks, we mastered ultrafine particle dispersion technology. Our PTFE dispersion applies this expertise to distribute fine PTFE particles, unlocking the benefits of this high-performance engineering plastic. Empower your products/processes with the unique properties of PTFE using our innovative dispersion solution.
Mitsubishi Pencil enhances battery performance with innovative dispersion technology, optimizing the effectiveness of carbon nanotubes (CNTs) as a conductive additive
Mitsubishi pencil’s battery graphene dispersions for conductive agents has proven results in charge/discharge cycle improvement
By using mixing and molding technology initially developed for writing instruments we have been able to manufacture dry electrodes, which are the next-gen electrode technology that is expected to reduce the environmental impact by eliminating the need for drying processes and the use of solvents.
Mitsubishi Pencil has a longstanding tradition of integrating carbon materials into its writing instruments. Our Plastic Formed Carbon (PFC) product line applies this expertise to a wide range of applications. PFC boasts high purity and mechanical stiffness, along with key characteristics of carbon materials such as electrical conductivity, thermal stability, corrosion resistance, and biocompatibility. These properties make it suitable for various industries and diverse applications.
Carbon products leverage the exceptional properties of their base material: lightweight and stiff, making it ideal for diaphragms and ultrasonic matching layers. Its hardness and tribological features make it perfect for sliding elements. By controlling pore size, we can fine-tune the material's characteristics for optimal porosity. With excellent corrosion resistance and electrical conductivity, PFC is the material of choice for electrodes.
The years of experience creating writing instruments allowed for great advancements in product development.
By optimizing our original conductive filler, conductive fibers and thermoplastic resin, we have achieved a high level of balance between each physical property.
From mechanisms to dispense fine amounts of liquid accurately and suitable for high temperature and pressure environments, to ones that work with highly viscous or aggregate-prone liquids, these technologies can be adapted and customized according to client’s needs.
