Physics:Sodium Hydroxide Regular:caustic soda; M.F:NaOH M.V:40
1; Character :
30%Caustic Soda Lye is liquid with colorless and bright, the gravity is 1.291
99.5%solid caustic soda is white solid ,the gravity is 2.13 ,character is alcali ,strong scour for skin ,forbe and paper . Keep out of wetness and air . caustic soda chemical character is very activitied,it is important chemical materials
2; Applications:
Manufacturing of Dyes and Pharmaceuticals, Rayon, Pulp and Paper, Aluminium Metal, Sodium Salts, Petroleum Products, Rubber Chemicals .Besides using for traditional industries,it can be used directly in other industries that require caustic soda of high quality, such as synthetic fiber, medicine, water treatment, petrochemical and so on.
Due to apply the 1st art of produce technology ,Our caustic soda can meet with requirement of many industries . 30% caustic soda lye standard Q/XJJ.02.11-1998 45% caustic soda lye and solid caustic soda standard Q/XJJ.02.01-1998
