A leader on the electronics markets, Febex offers two ranges of high purity products.
Electronics is Febex’s main market, thanks to its dedicated products of the highest purity and its long-standing expertise. Our high technology equipments, such as the clean room, position us as the leader on the European markets.
In 1989, Febex produced its first electronic-grade phosphoric acid. Benefiting from 25 years’ experience, analyses and development, we have acquired world-renowned expertise in the electronics sector. Febex developed its range of products to cater to the specific requirements of its markets.
Phosphoric Acid Range
The production of phosphoric acid is made up of different steps, resulting in different qualities depending on the application. Electronics requires the highest possible purity, especially in regards to metals such as iron. Several purification steps ensure that impurities do not exceed the level of the ppb. The production unit of the electronic grades is situated in a dedicated building.
Processing takes place in a clean room and is monitored by a particle counter. Any form of exterior contamination is thus excluded throughout the production chain. The choice of production equipment is strategic to prevent contamination by metals, particularly iron, chrome, or nickel, or by alkalines.
Superbex, with an iron content below 2 ppm, is mainly used in first generation electronic equipment component production plants and in the TFT-LCD screen industry.
Ultrabex is electronic-grade with ultra-low iron contents: from 200 ppb (IC200) to 50 ppb (IC50). With minute traces of impurities and stringent analyses, Ultrabex is ideal for applications requiring an extremely high purity and particle control, such as the manufacturing of electronic microchips.

Sodium Hypophosphite Range
Sodium hypophosphite, marketed under the brand Sofibex, is produced from a mixture of lime, caustic soda and phosphorus. The quality of the finished product depends on the strict sourcing of the raw material. The production line is exclusively dedicated to the manufacturing of Sofibex.
Febex is the only producer outside of China, and its Sofibex is greatly appreciated on the market of electroless nickel plating, especially by the manufacturers of hard disks. The unique quality of Sofibex Swiss Made enables the incorporation of more than 11% phosphorus in the layer of nickel, rendering it amagnetic. Due to Sofibex’s excellent solubility, the nickel plating is homogeneous and completely amorphous, ensuring an extremely efficient protection against corrosion and heat.
