Modification of the Recipe of Industrial PVC Plastic for Increasing its Fire Resistance

A directed modification of the formulation of industrial PVC plastic brands I40-13A was carried out using zinc borate, antimony oxide and chalk. It was found that the introduction of these additives into the compound can significantly increase the values of the oxygen index and the coke residue of the initial PVC plastic. It was found that a modification of the formulation of industrial PVC plastic leads not only to an increase in fire resistance, but also to a noticeable improvement in the basic physical and mechanical properties of the compound. It is shown that with a slight modification in the formulation of industrial PVC plastic compound it is possible to obtain materials that meet fire safety requirements
