The world's third largest pentaerythritol production facility

Exports of 88% of the polyols production

The plant in Tortosa (Tarragona) is one of the world's leading producers of polyols (pentaerythritol, dipentarerythritol and sodium formate). This centre supplies practically all consumers of polyols in the Spanish market and exports the rest of its production, 88%, to more than 50 countries.

Polyols are mainly used to manufacture synthetic resins and lubricants; paints; PVC stabilisers; and printing inks. These products use formaldehyde as a raw material, which is produced in the same factory. In Tortosa there are three formaldehyde plants, two pentaerythritol plants and one dipentaerythritol plant. Their overall production capacity is 310,000 t/year.

The R&D department of the intermediate chemicals division, to which the plant is integrated, is located in this centre. This department has developed the ErcrosGreen+ and ErcrosTech ranges, which are resins with advanced environmental and technological properties.

The workforce at the Tortosa plant is over 110 people.
