Hengcheng's micro pearl silica is made from sulfuric acid and sodium silicate. By using the pressure spray drying technology, it provides our customers with non- dusting micro pearl silica that is denser than powder and easier to handle. We offer several packaging options. These include paper bags and big bags, on plastic or wood pallets, and in bulk in specially lined containers. This enables us to deliver anywhere in the world and according to customer needs and preferences.
