Factory Introduction
The Sodium Metabisulphite factory we are representing was established in1984 and it is one of the oldest Sodium Metabisulphite factory in China. our factory's production capacity is around 2000MT/Month. Our Sodium Metabisulphite's main purity is 97%MIN and there are two grades including tech grade and food grade.We have ever exported Sodium Metabisulphite to Canada and Australia for mining; to America for textile industry; to Thailand and India for food industry; to Switzerland and Malaysia for water treatment; to Egpyt and South Africa for tannery.
