Catalysts technologies

1971 Start of manufacturing epoxy resins

Resins technologies

Resin-synthesis technology, processing technology, evaluation technology, etc.

1994 Start of manufacturing airbag inflators

Creation of New Products and Businesses by the Fusion of Basic Technologies

The basic technologies of Nippon Kayaku are related to fine chemicals that are based on original products developed in the fields of explosives, dyes, pharmaceuticals, and subsequently, resins such as epoxy resins for the encapsulation of semiconductors. And from the fusion of these technologies, new products and businesses have been created.

First, by applying the ignition technology related to the field of explosives, the business of developing and manufacturing micro gas generators and inflators for ensuring safety in automobiles was started. Moreover, by fusing our technologies for low-molecular-weight compounds synthesis (pharmaceuticals) and high-molecular-weight compounds synthesis (resins), "polymeric micelle anti-cancer drugs" that incorporated a drug delivery system (DDS) were created; these drugs are currently undergoing clinical trials.

Furthermore, the technologies for the synthesis and compounding of dyes have been applied to colors for inkjet printers and color filters for digital cameras, etc. By fusing these technologies with the resin manufacturing technology, the businesses of polarizing films and photo-functional films were started.

In the future, we will not only create new products and businesses by strengthening and expanding our technologies but also develop new basic technologies by fusing and integrating our various preexisting technologies.
