Piana, M., Gardi, S., Sarti, G. (2024, September). Paper present at PVC Formulation 2024, Düsseldorf, Germany.
This paper examines the evolution of poly(vinyl chloride) compounds used in cable manufacturing, focusing on the key drivers for replacing hazardous chemicals in PVC or PVC-based compounds with halogen-free alternatives, particularly concerning additive issues and fire performance.
The environmental benefits of PVC are emphasized, along with advancements in reducing smoke and acidic effluents during fires. The paper highlights the role of stringent European Union regulations and directives, such as RoHS, REACH, and CPR, in driving the development of more sustainable PVC formulations.
Furthermore, it explores the creation of new low-smoke, low-acidity compounds for cables that incorporate advanced flame retardants, smoke suppressants, and acid scavengers, demonstrating how these compounds meet and exceed fire safety standards in terms of heat release, smoke production, and effluent toxicity.
Additionally, it addresses common misconceptions, including the belief that modern PVC cables still contain hazardous additives, cannot be recycled, and produce dense black smoke and toxic emissions, making them less sustainable than halogen-free alternatives.
The findings support the conclusion that PVC remains a viable and often superior option for cable applications in today’s increasingly competitive and environmentally conscious market, mainly due to its sustainability and adaptability to stricter fire safety regulations.
