THERMINOL 55 Resistant O-Rings and Seals
Therminol 44 is also known as Therminol VP-1 or Dowtherm A and is a high temperature heat transfer fluid used in a range of applications, such as air conditioning, chemical processing and manufacturing. When rubber is exposed to Therminol 44, it is susceptible to swelling and cracking, which can greatly reduce its durability and strength. Additionally, oxidation, which can cause cracking in the rubber over time, may be accelerated when exposed to the chemical.
