On the possibility of upgrading the composition of cable PVC compound

Upgrade of the composition of cable PVC-compound grade I40-13A with aluminum hydroxide has been carried out. Fire resistance, thermophysical and physical-mechanical properties of the obtained compounds have been investigated. It is shown that the modernization of the composition of cable PVC compound with aluminum hydroxide enables production of a fi re-resistant compound. It was found that aluminum hydroxide significantly changes the thermophysical properties of cable plastic compound. In particular, heat generation and smoke generation during plastic compound combustion are significantly reduced. It has been established that the physical-mechanical and rheological characteristics of the cable compound modernized with aluminum hydroxide remain at the level of the original compound. The optimal amount of aluminum hydroxide for the modernization of cable plastic compound of the I40-13A grade is 10–15 wt.%.
