Highly activated bleaching earth

Type:ATL-4

Product description

ATL4 is a highly active bleaching earth used in a wide scope of applications. It is manufactured by acid activation of calcium bentonite.

ATL4 is well suitable for the removal of polar compounds like chlorophyll, carotinoids, phospholipids and peroxides, via chemisorption and acid catalysis.

ATL4 is very suitable for refining vegetable and animal oils and fats, moreover for finishing and/or reprocessing numerous types of mineral oils, paraffins and waxes.
