From the smartphones you use on a daily basis to the waterproof jacket you wear on a rainy day, per- and poly-fluoroalkyl substances (PFAS) are present in many everyday electronics. However, these substances pose significant health and environmental risks, and their usage is being restricted by environmental regulations. Thus, learn about the risks associated with these hazardous substances in electronics and discover practical ways to reduce your exposure.

Audit your supply chain. Look at your PFAS and/or fluorine content. You can accomplish these using certificates of compliance, test reports, material disclosures, and/or safety data sheets (SDS).
Do risk assessments.

Polymer PFAS

This type of PFAS is made up of a long chain structure with repeating units of fluorinated organic molecules. Typically, they are in applications requiring high chemical and thermal stability. Thus, these PFAS, like PTFE, are commonly present in articles i.e., physical products.

Non-Polymer PFAS

By contrast, this type of PFAS consists of short-chain molecules. Additionally, they contain fewer repeating units of fluorinated organic molecules. Frequently, this type is for applications requiring lower viscosity and better solubility. Therefore, they are usually present in chemical mixtures.

PFAS are used because they provide critical performance benefits, including:

Resistance to heat and chemicals

Excellent electrical insulation

Water and dirt repellency

Durability in harsh environments

These properties make them difficult to replace in high-performance electronics.

Identifying PFAS requires a combination of:

Supplier declarations and material disclosures

Full Material Declarations (FMD)

Targeted laboratory testing (e.g., LC-MS, total fluorine screening)

Supply chain transparency is critical due to hidden PFAS in components and processes.
