The history of AEROSIL®

The shortage of raw materials and resources on our planet has been a hotly debated topic for several decades. The ”black gold” in particular inspired many to become active researchers. The people at former Degussa, now Evonik Industries, were also enthusiastic about the idea of one day finding a substitute for oil. This is why, in 1941, they began to develop a white filling material for the tire industry as a substitute for industrial carbon black, which, up to then, could only be produced from oil. Just twelve months on, having created high-temperature flame hydrolysis, they succeeded in producing the first ultrafine-particle pyrogenic silica. Their vision became reality and the brand known as AEROSIL® was born.

This success story took its course, and in 1966, an important foothold was established in Asia with the building of the Nippon Aerosil production plant in Yokkaichi, Japan. In 1976, the same step was taken westwards when the production of AEROSIL® began at the new Degussa plant in Mobile (Alabama/USA).

More than 70 years of experience, development and research have by now made AEROSIL® the most frequently used brand for the creation, modification and characterization of surface effects.
