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.
