Description

Galden® HT PFPE are inert, dielectric and high-performance heat transfer fluids with boiling points ranging from 55°C to 270°C. This range is broader than other fluorinated heat transfer fluids and enables PFPE to be used at end-use temperatures up to 290°C. Solvay Specialty Polymers offers a safe Heat Transfer (HT) media for deman ding applications, including: – Semiconductor – Chemical – Pharmaceutical – Vapor phase heating – Transformer and super computer cooling – Recirculating chillers – NuclearGalden® HT PFPE are inert, dielectric and high-performance heat transfer fluids with boiling points ranging from 55°C to 270°C.
