3 Requirements
3.1 Grades
Aluminum hydroxide according to the chemical composition and physical properties are divided into two grades. AH-1, AH-2.
3.2 chemical composition and physical properties
Chemical composition and physical properties of aluminum hydroxide should meet the requirements in Table 1. Values in the table according to the provisions of GB/T 8170 and were rounding determination.
