The selection of appropriate flame retardants for polymers like Polypropylene (PP) and Polyethylene (PE) is a critical decision for manufacturers, impacting product safety, regulatory compliance, processing efficiency, and environmental footprint. Historically, halogenated flame retardants, particularly those containing bromine and chlorine, have been widely used due to their high efficacy. However, mounting concerns regarding their environmental persistence and the toxic byproducts released during combustion have spurred a significant shift towards halogen-free alternatives. NINGBO INNO PHARMCHEM CO.,LTD., as a key manufacturer and supplier in this sector, highlights the advantages of our advanced halogen-free flame retardant powder for PP and PE.

Halogenated Flame Retardants: The Traditional Choice

Halogenated flame retardants function primarily by releasing halogen radicals in the gas phase during a fire. These radicals interrupt the radical chain reactions that sustain combustion, effectively quenching the flame. They are known for their high efficiency and cost-effectiveness in many applications. However, their drawbacks are substantial:

  • Environmental Persistence: Many halogenated compounds are persistent organic pollutants (POPs) that do not easily break down in the environment and can bioaccumulate in living organisms.
  • Toxic Combustion Byproducts: When exposed to fire, halogenated flame retardants can release highly toxic and corrosive gases, such as hydrogen halides and dioxins/furans, posing severe health risks to humans and damaging property.
  • Regulatory Scrutiny: Due to these concerns, regulations like RoHS and REACH in Europe, and similar initiatives worldwide, are increasingly restricting the use of many halogenated flame retardants.

Halogen-Free Flame Retardants: The Sustainable Solution

Halogen-free flame retardants, such as our phosphorus-nitrogen based powder, offer a compelling alternative. They typically work through mechanisms in the condensed phase, promoting char formation that acts as a thermal barrier, and in the gas phase by releasing inert gases that dilute oxygen and fuel. Key advantages include:

  • Environmental Friendliness: These additives do not release toxic halogenated byproducts during combustion, leading to significantly less smoke and a reduced environmental impact. They also generally exhibit better biodegradability and lower bioaccumulation potential.
  • Improved Safety Profile: Reduced toxicity during fire events enhances safety for both end-users and manufacturing personnel.
  • Regulatory Compliance: Our products meet current and evolving environmental regulations, ensuring market access and product viability.
  • High Performance: Our specific formulation for PP and PE delivers excellent flame retardancy, achieving UL 94 V-0 ratings, along with high thermal stability (>275°C decomposition temperature), low smoke emission, and minimal mold corrosion. This offers performance that is often comparable or superior to halogenated alternatives.
