PFAS (perfluorinated and polyfluorinated alkyl substances) are fundamental components of modern sealing technology.

Particularly in the form of materials such as PTFE, FKM and FFKM, they offer outstanding properties: extreme chemical resistance, high thermal stability and exceptionally low friction. These advantages make PFAS-based seals the standard for demanding applications in the chemical and process industries:

• Chemical and process industries
• Food and pharmaceutical production
• Mechanical and plant engineering
• Hydraulics and motor technology

Current challenge: Sustainability & regulation

Due to their environmental persistence and potential health risks, PFAS are regulated throughout Europe - with far-reaching consequences for sealing technology. The EU is working on a far-reaching restriction proposal that requires adjustments and innovations.

Important facts:

• For many highly demanding applications, there are currently no equivalent, PFAS-free alternatives.
• PFAS-free means: no intentionally added PFAS - a complete analytical exclusion is hardly possible.
• The industry is intensively searching for solutions to combine regulatory requirements and the highest quality standards.

Our answer: progress & responsibility

We accompany the change:

• Customised advice on the selection of suitable sealing materials
• Modern production processes for maximum safety and quality
• Development and testing of PFAS-free alternatives, e.g. based on TPU or UHMW-PE
• Transparent communication on material properties, risks and legal requirements

PFAS-free seals have already been tried and tested in less extreme applications. For many key applications, however, specialised fluoropolymers remain the current state of the art.
