An Overview of Precision Associates' Capabilities and Products

Click here to view our: Capabilities and Products Brochure.

As PFAS regulations shift from discussion to active enforcement, OEMs in the medical, aerospace and industrial sectors face a critical turning point. The fluorinated materials that have been industry standards for decades, including FKM, FFKM and PTFE, are now under intense regulatory scrutiny.

To help you navigate this transition, Precision Associates (PAI) has released a new white paper: Futureproofing Your Products Against PFAS Restrictions.

This guide outlines the technical and operational steps OEMs must take now to protect market access and avoid supply chain disruptions.

Inside the White Paper:

• The Three Pillars of Risk: Understanding market access, supply chain vulnerability and qualification bottlenecks.
• Potential PFAS-Free Alternatives: A look at how materials like HNBR, Silicone and EPDM can serve as viable, high-performance substitutes.
• The 5-Step Roadmap: A practical strategy for identifying exposure, prioritizing high-risk parts and beginning the validation process.
• The Qualification Challenge: Why the transition can take months and how to streamline your testing and documentation.
