PTFE Products Properties:
TEMPERATURE RESISTANCE
- Temperatures above 77°C are not favorable for components of most elastomers and plastics, whereas PTFE withstands temperatures as high as 260°C. Even below 77°C, if acids corrosive to metals and organic solvents are combined, liners and components of PTFE are often preferred because elastomers and other plastics often lack resistance to solvent swelling and softening.
CHEMICAL INERTNESS
- By Chemical inertness, we mean that PTFE fluorocarbon resins can be in continuous contact with another substance with no detectable chemical reaction taking place. In general, PTFE fluorocarbon resins are chemically inert. Nevertheless, this statement, like all generalizations, must be qualified if it is to be perfectly accurate. The qualification will not lead to confusion, however, if one keeps in mind the basic facts about the behavior of PTFE resins. More details.
ABSORPTION
- In contrast to metals, plastic and elastomers absorb varying quantities of the materials they contact, especially organic liquids. Absorptivities in PTFE are unusually low, and a chemical reaction between the plastic and the other substances is a rarity (with the few exceptions noted previously). However, when absorption is combined with other effects, this property can influence the serviceability of these resins in a particular chemical environment. More details.
PERMEATION
- Permeation is a factor closely related to absorption, but it is also a function of other physical effects, such as diffusion and temperature. In over 20 years of experience with PTFE lined pipe, the number of failures attributed to permeation of a corrosive vapor followed by corrosion of the support member have been remarkably few. The liner thicknesses of 1.27 to 6.35mm necessary for physical strength at high temperatures reduce permeation to the point that it is normally a minor consideration. More details.
