3. Application: MAPO is mainly used as a crosslinking agent for the coating layer of propellant to enhance mechanical properties. In AP/HTPB propellant, it is also used as a bonding agent. In industry, MAPO is also used as a crosslinking agent for polymer compounds, polymer materials and industrial resins. It is also used as a raw material for pharmaceuticals and agricultural chemicals, as a processing aid for textiles, paper, leather, etc., to enhance the mechanical properties and anti-aging performance of products. MAPO is also a male sterile insecticide, commonly used in the preparation of anti-fertility rodenticide products for rodent control.

4. Safety instructions: Toxic. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing to avoid contacting with skin, eyes and clothing.
