Bausano in many years of production, research and development of plastic extrusion with additive and fillers worked also with Magnetite. It is a naturally occurring iron oxide with the chemical formula Fe3O4. It is mined from several deposits worldwide and although most is used to make iron and steel, the many special properties of magnetite have led to several other applications including as a filler for plastics and coatings.
A black lustrous powder with unusual properties. Often used for its high density (5.2 gcm-3 for pure grades). It also has high thermal conductivity and quite high electrical conductivity. It is x-ray opaque and can be used to block radiation.
The first commercial application in polymers was developed in the late 1990s.
