Fluoropolymers Chemical Resistance
All Fluoropolymers, and especially PTFE, have excellent chemical properties.
The chemical resistance is nearly overall with only few limitations, which can be summarized as follow:
| Fluorinated Hydrocarbons | Swelling (reversible after short-term exposure, not reversible after long term exposure) |
| Alkali metals, in solution or molten state | Fluorine elimination/Polymer destruction |
| Halogens, Elementar Fluorine, Chlorine-Trifluoride | At very high temperatures possible chemical reaction with polymer destruction (possible explosion) |
| Monomers: Styrene, Butadiene and Acrylonitrile | Possible penetration / Spontaneous polymerization may destroy the polymer |
| High energy radiation | Gamma radiation: physical properties can be reduced by approx. 50% already with 10kGy dosage |
| Nitrating acid: mixture of concentrations H2SO4 and HNO3 | At high temperatures (>100°C) possible decomposition of the fluoropolymer |
PFA excels in all the properties and characteristics offered by both PTFE and FEP.
Range of working temperatures
from -70°C (-95°F) to 260°C (500°F)
Longer and improved flex-life
