Descrizione del prodotto

TONSIL® 4120-A FF is a highly active bleaching earth for special applications. It is manufactured by acid activation of calcium bentonite and blended with an amount of 5 % activated carbon. TONSIL® 4120-A FF is a fine, greyish-dark powder showing a highly porous inner structure and a multitude of acid sites upon its surface. TONSIL® 4120-A FF possesses an outstanding adsorptive capacity for removal of polar compounds like chlorophyll, phospholipids, peroxides, via chemisorption and acid catalysis as well as unpolar components as for example carotenoids and polycyclic hydrocarbons (PAH). TONSIL® 4120-A FF is very suitable for refining vegetable and animal oils and fats, which are difficult to bleach. It is also highly recommended for decolourization of natural waxes.
