OPL Non Ferric Alum - Product Overview
Alum is essentially aluminium sulphate with the empirical formula Al2 (SO4)3.18HO. It is of two types (i) Ferric and (ii) Non Ferric.
Non Ferric Alum is a purer form of aluminum sulphate. It is used in better grades of paper for loading and sizing purposes. Non Ferric Alum is manufactured from aluminium trihydrate whereas ferric alum uses bauxite as the raw material. The raw material is cooked with sulphuric acid under suitable conditions. The resultant product is cooled in suitable moulds to slabs. It is available both, in solid and in liquid forms. At Orient Packagings Ltd. we have both products.
