PFAS-Free Materials: Compliance, Sustainability, and End-Use Performance Shape Material Choice
PFAS-free material selection is becoming more important as companies respond to evolving global regulations, consumer demand, sustainability goals, and supply chain risk. For OEMs and processors working with plastics, the shift away from PFAS requires more than simply removing a material from a specification. It requires a practical understanding of why PFAS have been used, why they are under scrutiny, and what alternative materials can support the performance requirements of the application.
PFAS-Free Solutions: How Material Selection Supports Compliance and Performance
Conventus Polymers helps customers identify PFAS-free materials that meet performance, compliance, and sustainability goals tailored to their unique applications. For programs where flame retardance, chemical resistance, water resistance, low friction, wear resistance, or other functional requirements matter, the right material strategy can help support the transition away from PFAS while maintaining application performance.
PFAS Are Widely Used Because of Their Functional Properties
PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals characterized by a high level of fluorination. In plastics, they have been widely used because they can provide resistance to water, grease, heat, and UV rays.
Thousands of PFAS compounds have been developed, each with distinct functional properties. That has made PFAS a versatile and widely used class of chemicals across many applications. However, those same characteristics also make PFAS difficult to break down, which is why they are often called “forever chemicals.”
Why PFAS Are Concerning
PFAS have a unique structure that makes them both water- and fat-repellent. This can give them the potential to bind to proteins instead of dissolving in the body, introducing the possible risk of PFAS entering cells, accumulating, and interacting with biological substances.
Several factors contribute to the concern around PFAS:
- Hydrophobic and lipophobic properties: PFAS repel water and fats, helping them avoid breakdown and removal by the body.
- Protein binding: PFAS can bind to proteins, helping them move through the body and accumulate in tissues.
- Strong chemical bonds: Their carbon-fluorine bonds make them extremely durable and resistant to breakdown.
- Bioaccumulation: PFAS can remain in the body and environment for a long time.
- Potential health effects: Their buildup may interfere with biological processes such as hormone function or organ health.
Because of their persistence in the environment, potential links to serious health issues, and increasing regulatory restrictions, PFAS are under intense global scrutiny.
Why Companies Need PFAS-Free Solutions
Companies are making the switch to PFAS-free materials for several connected reasons. Evolving global regulations are placing more pressure on manufacturers to understand where PFAS may exist in their materials and supply chains. At the same time, customers and consumers are increasingly looking for safer, more sustainable products.
PFAS-free solutions can help companies:
- Stay compliant with evolving global regulations
- Meet consumer demand for safer, more sustainable products
- Future-proof supply chains with safer, scalable alternatives
For plastic applications, that shift requires a material selection process that accounts for both compliance expectations and end-use performance. A PFAS-free material still needs to function in the application, process effectively, and support the requirements that originally led teams to consider PFAS-based materials or coatings.
PFAS-Free Does Not Always Mean the Same Thing
Plastic resin suppliers are taking a few different approaches to helping customers find PFAS-free solutions. One approach is certifying materials as PFAS-free. Certifications for PFAS-free materials are still in development, but one plastic-specific PFAS test and certification has started to be used: UL 746G for plastics and recycled plastics.
UL 746G includes three different levels of certification:
- Non-fluorine materials
- Non-PFAS materials
- Non-PFAS with total fluorine ≤50 mg/kg not due to polymeric PFAS
Another approach is labeling materials as “PFAS not intentionally added.” When a plastic is labeled this way, it means PFAS were not deliberately used during the manufacturing process. However, that label does not guarantee the product is entirely PFAS-free, as trace amounts may still be present due to contamination or materials used upstream.
For customers, that distinction matters. “PFAS-free,” certified PFAS-free, and “PFAS not intentionally added” are not interchangeable terms. Understanding the difference helps teams evaluate material options more clearly and communicate expectations across the supply chain.
PFAS Alternatives Should Be Matched to the Application
Replacing PFAS is not only a compliance exercise. It is also a design and performance challenge. Choosing the best polymer family for the application, or using additives to supplement deficient properties, can often meet or exceed the performance of materials that used PFAS for flame retardance, chemical resistance, water resistance, and other functions.
For example, an application that need a slippery surface, POK can provide a low coefficient of friction and good wear resistance. Alternatively, a silicone additive can also be used as a lubricant.
For applications that need increased chemical resistance, PEEK or a sulfone can help increase the part’s chemical stability.
This application-specific approach matters because PFAS may have been used for different reasons depending on the part, environment, and performance requirements. A PFAS-free replacement should be selected based on what the material needs to do, not only what it needs to avoid.
Conventus Can Help
Conventus partners with both our suppliers and customers to identify PFAS-free materials that meet performance, compliance, and sustainability goals tailored to unique applications. That process can include evaluating whether a certified PFAS-free material is needed, whether a “PFAS not intentionally added” material is appropriate, or whether an alternative polymer family or additive strategy can support the application’s performance requirements.
For companies working through PFAS-related material changes, the goal is not simply to remove PFAS from a specification. The goal is to identify a practical, scalable material solution that supports compliance expectations, supply chain stability, sustainability goals, and the performance demands of the finished part.
