Galden® PFPE – Heat Transfer Fluids

Galden® PFPE - High Performance Dielectric Heat Transfer Fluids

Galden® PFPE is a family of advanced fully fluorinated fluids specifically developed for use in high-demand industrial environments. These fluids are chemically inert and deliver outstanding dielectric properties, superior chemical resistance, and consistent performance across an exceptionally broad temperature range—cryogenic conditions to extreme heat. Their boiling points extend 55°C to 270°C (131°F to 518°F), while their recommended operating range spans -70°C to 290°C (-94°F to 554°F), making them a highly versatile solution for critical applications in harsh conditions.

Key Application Areas

Galden® PFPE fluids are widely applied in industries including semiconductor manufacturing, electronics testing and thermal management, carriers for fluorinated lubricants, solar energy systems, chemical processing (CPI), battery production, pharmaceutical manufacturing, and food-related processes.

In the electronics and semiconductor sectors, Galden® PFPE fluids play a vital role in multiple high-precision applications. They are used as heat transfer media in electronic component production, as dielectric testing fluids for evaluating thermal shock resistance and hermetic sealing integrity, and as working fluids in the Vapor Phase Soldering (VPS) process for assembling components onto printed circuit boards.

Galden® PFPE Product Range

The Galden® PFPE portfolio consists of specialized fluid grades designed to meet the specific performance requirements of different industrial processes.

Product Line	Primary Use	Performance Characteristics
Galden® HT	Heat Transfer Media	Developed for safe and efficient heat transfer in extreme environments over a wide temperature range. High Boiling (HB) grades operate between 150°C and 290°C and provide significantly lower evaporation losses compared to Low Boiling (LB) grades.
Galden® D	Electronics Testing	Engineered for electronic reliability testing, including thermal shock evaluation and hermetic seal assessment.
Galden® LS/HS	Vapor Phase Soldering (VPS)	Precisely formulated for VPS applications with tightly controlled molecular weight distribution and stable vapor temperature behavior.
Galden® SV	Precision Cleaning Solvents	Low molecular weight, CFC-free solvents designed for cleaning operations. They can be applied to heated components, preheated prior to use, or sprayed under pressure, and also serve as carriers for fluorinated lubricants.
