Innovative tech enhances plastic safety
Researchers at Kabardino-Balkarian State University in Russia have developed a low-cost additive for PVC (polyvinyl chloride) materials and insulation wires that helps reduce their flammability. The additive is based on a mixture of four chemicals that form a char layer when exposed to heat, limiting oxygen access and slowing flame spread, while releasing non-flammable gases such as nitrogen and ammonia during combustion. The formulation, with an optimal ratio of 2:3:2, enhances fire resistance and contributes to reducing the production costs of electrical wires and cables.
