High Purity Molybdenum Trioxide

Introduction

Molybdenum Trioxide Smoke Suppressant is an additive flame retardant with dual functions of flame retardancy and smoke suppression. Compounding with other flame retardants can reduce cost, improve flame retardancy of Molybdenum Trioxide Smoke Suppressant and reduce smoke. Molybdenum Trioxide Smoke Suppressant also has the dual effects of flame retardant and smoke suppression. Molybdenum Trioxide Smoke Suppressant shows a certain synergistic effect with aluminum hydroxide trihydrate and antimony oxide. 

Molybdenum Trioxide Smoke Suppressant is more effective for chlorine-containing adhesives. The reference dosage of 0.5 to 5.0 parts of Molybdenum Trioxide Smoke Suppressant can reduce the amount of smoke produced by 30% to 80%, and increase the oxygen index by 10% to 20%.

In the gaseous state, molybdenum trioxide consists of MoO₃ molecules with double bonds between Mo-O. In the solid state, the anhydrous molybdenum trioxide is an orthorhombic system and contains a layered structure composed of deformed octahedral MoO6. The octahedron forms a chain, and there are oxygen atoms cross-linked between them, and a Mo-O (non-cross-linked oxygen) bond in the octahedron is short in length.
