Nippon Kayaku produces and retails a range of chemicals. By product category, the company divides itself into four areas. Epoxy resins used as flame retardants in electronics, colorants, and dyes used in inkjet printers and materials for the production of textiles are sold by the functional chemicals segment, which is the one that generates the most income of any segment. Pharmaceutical companies market anti-cancer, biological, cardiovascular, vitamin, and anti-inflammatory medications. The automotive sector is supplied by the safety systems segment with airbag inflators and micro gas generators for seatbelt pre-tensioners, both of which are intended to protect passengers in the event of an accident. Insecticides and herbicides are offered for sale in the agrochemicals market.
