Effect of MgO•Sb₂O₅ on Fire Resistance and Physical and Mechanical Properties of Cable PVC-Plasticate

Abstract:

Based on magnesium carbonate and antimony oxide (V), MgO•Sb₂O₅ was obtained. In the formulation of fire-resistant cable PVC-plasticate, antimony (III) oxide was replaced by MgO•Sb₂O₅ and the fire resistance and physical and mechanical properties of the resulting compound were investigated. It is shown that the replacement of antimony (III) oxide in the composition of PVC cable compound MgO•Sb₂O₅ leads to the production of a compound that is not inferior in its characteristics to the original plastic compound. In particular, the fire resistance of cable PVC-plasticate, standard industrial formulation and with the obtained MgO•Sb₂O₅, is practically the same (OI=32%). It has been established that the physical and mechanical characteristics of the cable compound, when replacing antimony oxide (III) with MgO•Sb₂O₅ in the formulation, remain at the level of the original compound, while MgO×Sb₂O₅ will have a less negative impact on the environment.
