GREENE TWEED’S<br>PFAS-Free Offerings
Greene Tweed’s purpose – to enable customers to operate efficiently and safely in the world’s most demanding environments – has been at the heart of our business for 160 years.
What Are PFAS?
Understanding PFAS and
Why They Matter
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals known for their durability and resistance to heat, water, and oil. However, their persistence in the environment has raised concerns about their impact on human health and ecosystems. At Greene Tweed, we are taking proactive steps to address these concerns, while maintaining the performance and reliability our customers depend on.
Greene Tweed’s Position in the Fluoropolymer Value Chain
Greene Tweed designs and manufactures materials and engineered components for the world’s harshest applications, where failure is not an option. We do not manufacture fluorinated polymers, nor use fluorosurfactants in our production processes.
Our Commitment
A PFAS-Free Innovation Roadmap
Greene Tweed's goal is to innovate using, where possible, PFAS-free and/or non-fluorosurfactant (NFS) polymers in the production of our materials.
Our sealing product compounds – tetrafluoroethylene propylene (FEPM), fluoroelastomer (FKM), and perfluoroelastomer (FFKM) – are considered polymers of low concern (PLC) by the Organization for Economic Co-operation and Development (OECD) Expert Group on Polymers due to their lack of bioavailability and toxicity, meaning they have insignificant environmental and human health impacts.
Through innovation, collaboration, and sustainability initiatives, we are providing PFAS-free and PLC solutions that meet the highest standards of performance and compliance.
Customer Collaboration

Greene Tweed's PFAS-Free Products
High-Performance Solutions Without Compromise
Our extensive portfolio of PFAS-free products – select materials and product lines made from PFAS-free and NFS polymers – is designed to meet the demands of critical applications across industries. From elastomers to thermoplastics and composites, we offer reliable alternatives that deliver exceptional performance.
Thermoplastics and Composites
Greene Tweed offers a growing range of PFAS-free plastics and high-performance thermoplastic composites for structural and engineered solutions, including:
| Arlon® | A tough, rigid material for components where thermal, chemical, and combustion properties are critical |
| WR® | Thermoplastic composites with non-galling, non-seizing performance and chemical resistance, with maximum service temperature of 273°C (525°F) |
| Xycomp® DLF | Proprietary thermoplastic composite offering up to 60% weight reduction versus metal; designed to replace complex-shaped metallic components |
| Orthtek® | Proprietary thermoplastic composite with excellent strength-to-weight ratio and radiolucence, ideal for structures used in surgical equipment and devices |
Elastomers
Greene Tweed is expanding our extensive existing portfolio of PFAS-free elastomer compounds to support more demanding applications, with solutions such as:
| EPM/EPDM | Highlighted compounds include 953, which offers performance in ultra-low temperatures down to -65°C (-85°F), and 823 & 826, nuclear grade materials with outstanding resistance to hot water/steam, polar solvents, and ozone |
| NBR/HNBR/XNBR | High durometer carboxylated NBR material; ultra-low temp NBR down to -60°C (-76°F) |
| AU/TPU | High molecular-weight urethane with strong performance in high and low temp environments |
