PTFE remains stable between a wide range of temperatures, from as low as almost -270⁰c to +260⁰c. Its stability and retention of physical properties at extremely low temperatures make it an ideal solution for cryogenic applications such as:
Cryogenic temperatures are below the scale of refrigeration temperatures and are generally considered to be between -150°c and absolute zero, which is -273°c
A range of coatings are available from almost pure topcoats to resinous single layer systems that can also function without loss of physical properties at temperatures as low as -195°c.
PTFE can provide excellent dry lubrication properties to mating surfaces that are exposed to cryogenic temperatures where traditional lubricants would freeze and become ineffective.
