    HYDROX* P40S Modified sequestrant

    HYDROX P40S allows to control bleaching processes with hydrogen peroxide through stabilization in a way that the highest possible degree of whiteness is achieved with little fibre damage. The product is suitable for processes with and without sodium silicate.

    HYDROX* P802 Acrylate copolymer

    HYDROX P802 is free from potassium and chloride, and therefore does not disturb the lye recycling. The highest stability to chemicals and temperatures allows the prevention of hardener deposits in heat exchangers, sieves, filters, pumps or other machine parts.

    HYDROX* P900 Modified polycarboxylates

    HYDROX P900 has an excellent sequestering and dispersing capacity towards alkaline earth metal ions and their salts. The product effectively prevents scale of insoluble inorganic salts and thereby contributes to increased productivity and to consistent pulp quality. Furthermore, it is particularly suitable for resin rich hardwood digesting processes in combination with tall oil.
