ASERCOM, the Association of European Refrigeration Component Manufacturers, welcomes the progress update from the European Chemicals Agency (ECHA) and the dossier submitters regarding the universal PFAS restriction proposal.

„We are particularly encouraged by the explicit recognition of fluoropolymers in sealing applications as a distinct subgroup within the updated sector assessments“, Marco Masini, ASERCOM president says. Sealing applications represent a critical use of fluoropolymers in the RACHP industry, where their unique properties – such as chemical resistance, temperature stability and low friction – are indispensable for ensuring the durability, safety and efficiency of compressors and RACHP-systems.

In addition to sealing applications, ASERCOM emphasizes the importance of maintaining access to other vital PFAS-based applications in the RACHP industry. For example:

  • Bearings made from fluoropolymers like PTFE are crucial for reducing friction and wear in compressors, ensuring energy efficiency and long system lifespans, even under challenging conditions such as oil viscosity reduction caused by refrigerants.
  • Cable and wiring insulation using materials like PTFE and FEP is essential for the safety and reliability of internal electrical components, offering high electrical resistance, low flammability and excellent durability in harsh environments.
  • Electronics components, such as printed circuit boards and capacitors coated with fluoropolymers, provide critical chemical and temperature resistance, ensuring the reliability of HVAC&R control and monitoring systems.

The RACHP solutions operate under extreme conditions, including high pressure and temperature fluctuations and chemical exposure. PFAS-based materials nowadays play an very important role in overcoming these challenges. Their use significantly contributes to the energy efficiency, sustainability and longevity of RACHP systems, aligning with the industry’s goals of minimizing environmental impact.

ASERCOM supports a balanced regulatory approach that acknowledges the importance of these applications while exploring feasible alternatives and minimizing emissions. We look forward to contributing further, science-based insights on these critical uses to the ongoing discussions, emphasizing their crucial role in energy-efficient and sustainable RACHP solutions.
