Molykote® DX(S), P-40(S), G-4500 FMS: Meeting Industry Demands Without PFAS
As environmental and health regulations evolve, the industrial sector is being driven to fundamentally rethink its practices—particularly in lubrication. The PFAS-free industrial lubricants in the Molykote® range reflect this shift toward safer and more sustainable solutions. Developed by DuPont™, Molykote® DX(S), Molykote® P-40(S), and Molykote® G-4500 FMS exemplify this commitment.
These technically advanced products enable industrial operators to maintain high-performance standards while aligning with growing societal and regulatory expectations regarding health and environmental safety.

What Does PFAS-Free Mean?
PFAS (per- and polyfluoroalkyl substances) are a broad class of synthetic fluorinated chemicals known for their resistance to heat, water, and chemicals. Widely used for decades across multiple industrial sectors, PFAS are now under scrutiny due to their environmental persistence and tendency to bioaccumulate, raising significant health and ecological concerns.
A PFAS-free product is formulated without the intentional addition of these substances. This ensures a safer alternative for operators and a lower environmental impact, in line with recent regulatory trends across Europe and internationally.

❓ FAQ – PFAS-Free Molykote Lubricants
🔹Why should PFAS be avoided in industrial lubricants?
PFAS are known as “forever chemicals” due to their extreme persistence. Their accumulation in soil, water, and living organisms poses significant health and environmental threats. Regulations, particularly in Europe, are increasingly restricting or banning their use.
🔹Are PFAS-free lubricants as effective as traditional products?
Yes. Molykote PFAS-free lubricants are engineered to match—or even exceed—traditional products in terms of:
- Wear resistance
- Thermal stability
- Longevity
- Performance at both high and low temperatures
🔹 Do these lubricants comply with HSE regulations?
Absolutely. Molykote PFAS-free lubricants are formulated to meet stringent Health, Safety, and Environmental (HSE) standards, reducing operator risk and enhancing site compliance.
🔹How can I transition to a PFAS-free solution with Molykote?
Samaro offers tailored technical support to help you select and implement the best solution:
- Application analysis
- Product selection
- Technical datasheets and testing
- Implementation follow-up
🔹Does switching to PFAS-free lubricants require a full purge?
Ideally, yes. For optimal performance and to eliminate residual PFAS contamination, it’s best to clean existing deposits before applying a new PFAS-free lubricant. This is considered a best practice for a clean transition.
🔹Why make the switch to PFAS-free now?
- To stay ahead of tightening regulations
- To protect your operators from toxic exposure
- To enhance your CSR and sustainability profile
- Because performance is equivalent or superior
