Packaging & Shipping

 

Packing and delivering

Application

 

1. Stuffing agent in detergent powder
2. Paper making
3. Glass industry
4. Dye industry
5. Raw material for making Sodium Silicate

 

Important Notice

1. When SSA is exposed in air, it absorbs moisture and becomes sodium sulphate decahydrate (Na₂SO₄.10H₂O)
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)
