Application

(1). Phosphorous acid can be used as reducing agent, nylon whitening agent, also used as a sub phosphate raw materials, pesticide intermediates;

2). Phosphorous acid is the manufacture of phosphite is raw material, manufacturing plastic stabilizer (e.g. two lead phosphite) and organic phosphorus pesticide raw materials.
(3). Phosphorous acid can be used as a stabilizer for polycarbonate. Also used as an antioxidant for nylon 1010.
(4). Phosphorous acid can be used as chemical reagent;
(5). Phosphorous acid can be used as the determination of mercury, gold, silver and lead, reducing agent, acid, copper and cadmium test.
(6). Industrial phosphoric acid is the raw material for the manufacture of plastic stabilizer. Also used in the manufacture of synthetic fiber and sub phosphate.
