In the late 70s and early 80s the company continued to make a number of acquisitions. In 1978 KemaNord acquired Swedish civil explosives chemical group Nitro Nobel and Liljeholmens Stearinfabrik; in 1981 it acquired Swedish electronics group Pharos from AGA and a year later the paints group Nordsjö. In 1983 the group consolidated the food systems groups of KenoGard and Kema Nobel to form Probel, later called Nobel Biotech. In 1984 Bofors acquired majority interest in KemaNobel, both companies have historic ties to Alfred Nobel, the 19th century Swedish inventor whose invention of dynamite gave a safe way to manage the detonation of nitroglycerin. By 1985 Bofors had integrated the entire KemaNobel group into itself and changed its name to Nobel Industries.
