Elkem Siliconi Italia (former Bluestar Siliconi Italia) first facility started up in 1969. The Company changed its name several times: in 2000 we became Rhodia Siliconi Italia, Bluestar in 2007 and finally Elkem in 2017.

At the Plant, we have two main production capabilities: specialties and rubbers. Specialties include RTV 2, RT gels, paste and grease, and antifoam. Rubber consists of RTU products and masterbatches. From rubber, healthcare, speciality fluids and advanced molding and printing, to textile coating, sealing and bonding, and construction, the Caronno plant serves a great variety of segments.
