In the evolving landscape of polymer formulation, achieving effective flame retardancy is paramount. Traditional halogenated flame retardants (HFRs) have been widely used for their efficacy; however, growing environmental and health concerns have led to increased scrutiny and regulatory restrictions on these substances. As a result, industries are transitioning towards halogen-free alternatives that offer both safety and performance.
Environmental and Health Concerns of Halogenated Flame Retardants
HFRs, particularly those containing bromine and chlorine, have been associated with several adverse effects:
• Persistence and Bioaccumulation: Many HFRs are persistent in the environment, meaning they do not readily degrade. They can accumulate in living organisms, leading to higher concentrations up the food chain. Studies have detected these chemicals in human breast milk, blood, and fatty tissues, as well as in wildlife. (source)
• Health Risks: Exposure to certain HFRs has been linked to endocrine and thyroid disruption, immunotoxicity, reproductive toxicity, cancer, and adverse effects on fetal and child development and neurologic function. (source)
Regulatory Landscape in the United States and Canada
In response to these concerns, regulatory agencies in the United States and Canada have implemented measures to limit the use of certain HFRs (source):
• United States: Several states have enacted laws restricting or banning specific flame retardants in consumer products. For instance, Washington State has banned certain brominated flame retardants in home appliances. Additionally, multiple states have introduced legislation to prohibit the sale of products containing specific flame retardants, particularly in children’s products and upholstered furniture.

• Canada: Under the Chemicals Management Plan, Canada assesses and manages the risks associated with chemical substances, including flame retardants. Recent assessments have led to the proposal of bans on certain HFRs deemed to pose health risks. However, some decisions have been met with criticism for not encompassing a broader range of harmful flame retardants. (source)
