Description
Aflas® or TFE/P is a member of a new generation of fluoroelastomers compounded especially to provide unique properties for specific applications. The primary uses for Aflas are in parts for oil drilling equipment. Aflas can be crosslinked (cured) using a variety of systems, but generally peroxides are used to provide the best all around environmental resistance. A unique property of TFE/P is, that at very low temperatures (down to -54 °C) it takes on leathery consistency and remains functional, unlike many other rubbers which can often become brittle and shatter at low temperatures.
