Tokyoink

Plastic Chemicals Division

To meet increasingly sophisticated and diversifying needs in the field of plastics, we are working to provide a variety of products, including masterbatches and compounds by leveraging our dispersion and processing technologies.

Colorants for Plastic

Our colorants are used in plastic products found all around us, including in automobiles, home appliances, containers, and films, and we offer masterbatches, liquid colors, dry colors, and colorants to fit molding conditions and the resins to be used. We also provide colorants for thermosetting resins used in areas such as domestic equipment, and are working on colorings for a wide range of fields.

  • Colorant Masterbatches
  • Liquid Masterbatches
  • Dry Colors
  • Colorants for Thermosetting Resins

Functional Additives for Plastics

While plastics offer many advantages that include being lightweight and easy to mold, they also have disadvantages such as degradation from ultraviolet rays and being prone to combustion and electrostatic charge build up. We offer functional additives to make up for such disadvantages. By adding functional additive masterbatches during the molding process, it is possible to impart functionality such as weather resistance, flame resistance, and electrical conductivity to plastic. In this way, our products are also used for purposes other than coloring in places they cannot be seen. Our lineup also includes masterbatches for biodegradable resins.

  • Functional Masterbatches
  • Masterbatches for Biodegradable Resins

Compounds

We increase and improve the functionality of resins by blending, kneading, and alloying common resins and engineering plastic resins with colorants, additives, and various fillers in high concentrations. Electroconductive resin (PAPIOSTAT) has electrical properties thanks to the fact that it contains conductive carbon dispersed at a high concentration. We offer compound processing in a clean factory to meet requirements for high quality.

  • Functional Resin Compounds
  • Electroconductive Resin Compounds
  • Made-to-Order Compounds

Detergents

Our detergent lineup features nine brands covering injection and extrusion molding for use according to your molding method, the resin you use, purpose of use, and other such factors, and they offer a powerful cleaning and effective displacement solution.

  • PLACLAIRE for Injection Molding
  • POWERFUL PURGE for Extrusion Molding

Powder Resins

Our powdered resins are produced using the pulverization and blending technologies we have developed and refined over the course of many years.
Thanks to their excellent adhesive strength and various properties of thermoplastic resins, these resins are widely used in various fields as a hot melt adhesive, coating agent, sealant, modifier, and additives. We have also brought to market biodegradable resins and bio-olefin powder resins, which enable our customers to develop environmentally friendly products.

  • Various Powder Resins
  • Biodegradable Powder Resins
  • Bio Powder Resins

Other Functional Products

We also offer filaments for 3D printers, stage sealants, and, on the slightly unusual side, materials for radiation measurement.
Our heat dissipating materials include silicone-free two-component curable gap fillers customized to meet specific needs in applications including LiB, power modules, and high-heat applications.
