The unmatched benefits of Phosphorus-based Halogen-Free Flame Retardants

Enhancing fire safety with sustainable solutions: when it comes to the choice of flame retardant additives, the benefits of phosphorus-based halogen-free compounds are second to none

Ugo Zucchelli

Fire safety is vital in many industries. From manufacturing processes to electronic devices and plastics compounds, flame retardant additives play a critical role in inhibiting and slowing down the ignition of flames, while also preventing the release of toxic substances and reducing smoke formation in the event of fire. As companies strive to create safer environments and products, choosing the right flame retardant additive becomes crucial. Let’s delve into the world of flame retardant additives and explore why Phosphorus-based halogen-free flame retardants, thanks to their chemical properties, are the preferred choice in the fire safety field.

Phosphorus and Its Fire Safety Properties

There are many factors to consider when choosing a flame retardant additive, including:

  • Processing behaviour
  • flame retardancy
  • smoke toxicity
  • migration and aging
  • recyclability
  • chemical and physical properties
  • compliance with regulations and standards
  • toxicity profile
  • availability and cost

Great R&D efforts and industrial practice have shown that Phosphorus-based chemical additives are the best class of materials to fit all these requirements, allowing an optimal fire safety solution for various applications.

Phosphorus, with its various oxidation states and versatile chemical structures, offers a wide range of flame retardant options. Phosphorus-based flame retardants can be categorized into five different product families:

  • phosphate esters
  • phosphonates
  • phosphinates
  • polyphosphates
  • inorganic phosphorus compounds

Within these classes, the percentage of phosphorus content increases progressively, resulting in higher flame retardancy. Among these families, inorganic Phosphorus compounds, such as red phosphorus and inorganic phosphinates, offer the highest Phosphorus content and, therefore, more flame retardancy effectiveness.

Compared to traditional flame retardants based on Bromine or Chlorine in combination with Antimony Trioxide, Phosphorus-based compounds represent really a bright alternative. Apart from the Halogen-Free nature, one new possibility is to replace antimony trioxide in some polymers (polyesters, styrenics) at comparable loading level with increase of electrical properties like CTI. Another attractive possibility is to use Phosphorus-based synergic to reduce the hydrates loading or increasing the flame retardants performances of the compound.

Italmatch Chemicals, a global specialty chemicals leader, offers a wide portfolio of Phosphorus-based halogen-free flame retardants for thermoplastic and thermoset polymers. These compounds not only enhance fire safety but also show a favorable toxicological profile not harmful to humans or the environment, even once the compound is disposed or recycled.
