Company PR
Toda Kogyo is a chemical materials manufacturer based in Hiroshima, Japan. Founded in 1823, our roots can be traced to a group of engineers who produced bengara iron oxide particles, said to be the oldest pigment in Japan. Since then, for over 200 years, we have continued to create products that are needed by people and society while expanding the possibilities of fine particles with our unique technologies and passion.
In order to learn from 200 years of history and open the way to the future, we are now returning to our roots, enhancing added value and expanding applications of pigments and coloring materials for copiers and printers as our core business. On top of that, we regard high-quality magnet materials, dielectric materials, and materials for lithium-ion batteries as a growth business and supply these items to our customers and partners. These chemical materials and components are utilized in a wide variety of products, for example, smartphones, automobiles, and home appliances, that make life richer and more convenient for everybody.
Major Products
- Products for home appliances and ICT equipment(for magnetic tapes, magnetic cards, etc.)
- Product for the paint (color for the car, color for a building, building materials, rust prevention color for the bottom of a ship, paint for the office appliance)
- Automotive product (magnetic material (motor, sensor), materials (inductor for electronic parts, condenser), battery materials)
- Copier, product for the printer(toner materials, carrier, magnet materials (mug roll))
- Environmental materials (CO2 solid recovery materials, CNT, combustion catalysts, soil and groundwater purification materials, lead-free vinyl chloride stabilizers)
