ASASP represents the majority of synthetic amorphous silica (SAS) producers in Europe. SAS is a highly pure, crystalline-free, form silicon dioxide (SiO2). It white powder and also supplied in dispersions. There are two main production routes: the wet route for the production of precipitated silica and silica gel and the thermal route for pyrogenic (also called fumed) silica. SAS is used in a wide variety of applications including cosmetics, pharmaceuticals, food, tyres, plastics, insulation, coatings, inks and catalysts. Specific applications include as an abrasion additive in toothpastes, an anti-caking agent in foods to a reinforcement agent in tyres to improve fuel economy. The production volume in Europe exceeds 500,000 tonnes per year.
