Main types:
1. Regular SSA (Purity 98% min, whiteness 85% min, moisture 0.5% max, pH value of 5% solution 9~11, NaCl content 0.7% max)
2. Big granular SSA (Particle size slightly bigger than regular SSA, but it can not be tell by naked eyes, and bulk density is also the same with regular SSA).
3. Low Chloride SSA (NaCl content 0.1% max)
Packing and delivering
1. Stuffing agent in detergent powder
2. Paper making
3. Glass industry
4. Dye industry
5. Raw material for making Sodium Silicate
1. When SSA is exposed in air, it absorbs moisture and becomes sodium sulphate decahydrate (Na

O)
2. Even SSA is tightly closed in the containers or bags, it still can cake sometimes, if it can be easily crushed into powder again, then it's called a phenomenon of fake-caking, it won't influence the quality of the material
3. If the SSA is stocked in a warehouse, then there is no need to use UV-Resistant packing which is USD1/mt higher in cost
4. We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
