In the realm of electrical safety, the materials used in cables and wires play a critical role in preventing fire hazards. Traditional flame retardants often contain halogens, which can lead to corrosive smoke and toxic byproducts when exposed to heat or fire. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing safer material solutions, and this article explores the science behind halogen-free flame retardants, particularly phosphorus-nitrogen (P-N) based compounds, and their crucial application in cables and wires.

The electrical industry demands materials that not only provide excellent conductivity and insulation but also offer robust fire safety properties. Halogenated flame retardants, while effective, have raised significant environmental and health concerns due to the release of harmful substances such as hydrogen chloride (HCl) or hydrogen bromide (HBr) during combustion. These compounds contribute to severe corrosion of equipment and pose inhalation risks. Consequently, there has been a strong push towards halogen-free alternatives. Manufacturers are increasingly looking to purchase these safer options to meet stringent regulatory requirements and improve overall safety standards. Our P-N flame retardants offer a compelling solution to these challenges.

Phosphorus-nitrogen flame retardants, such as our TF-901, are designed to overcome the limitations of halogenated systems. These compounds work through multiple mechanisms to inhibit fire. Primarily, in the condensed phase, they promote the formation of a stable char layer on the surface of the polymer. This char acts as a physical barrier, shielding the underlying material from heat and oxygen and preventing the release of flammable gases. In the gas phase, decomposition products of P-N flame retardants can scavenge highly reactive free radicals (like H• and OH•) that propagate the flame, thus interrupting the combustion cycle. This dual-action approach makes them highly efficient. The good dispersibility of our TF-901 also ensures smooth surfaces on extruded wires, a key requirement for high-speed cable manufacturing.

The benefits of using these halogen-free solutions in cables and wires are substantial. They significantly reduce smoke generation and the release of toxic gases, leading to improved visibility and safer evacuation during a fire. Furthermore, they are free from corrosive halogens, protecting sensitive electronic components and infrastructure. Compliance with international standards such as UL1581 VW-1, a critical test for wire and cable flammability, is often achievable with the right P-N flame retardant formulation. For manufacturers, selecting these advanced additives ensures their products are not only safer but also more environmentally friendly. Businesses looking to purchase these specialized chemicals will find them to be a vital component for next-generation cable designs.
