Chemical Properties of Fluroethylenepropylene (FEP)
METHOD FOR STEAM CLEANING GOODYEAR ENGINEERED PRODUCTS
(Chem one,
VIPER, FABCHEM AND FABCHEM ARC)
As stated by E.I. du Pont de Nemours
5 IMPORTANT REQUIREMENTS
GENERAL INFORMATION
FEP fluorocarbon resins are attacked by certain halogenated complexes containing fluorine including:
chlorine trifluoride, bromine trifluoride, iodine pentafluoride and fluorine itself.
FEP is also attacked by such metals as sodium or potassium, especially in their molten states. Great care
should be used when mixing finely divided fluorocarbon polymers with finely divided metals, such as
aluminum, magnesium or barium, since these can react violently if ignited or heated to a high temperature.
Certain complexes of these metals with ammonia or naphthalene (in either solvent) also attack the products.
Certain metal hydrides such as boranes, aluminum chloride and certain amines have also been observed to
attack fluorocarbon resins at elevated temperatures.
The following materials are inert to FEP:
Alcohols
Aldehydes
Aliphatic Hydrocarbons
Anhydrides
Aromatics
Chlorocarbons
Esters
Ethers
Fluorocarbons
Inorganic Bases
Inorganic Oxidizing Agents
Ketones
Organic Acids
Salt Solutions
Strong Mineral Acids

1) Hose must be
open-ended
during steam cleaning.
2) Temperature of Steam–
Maximum 288°F
.
3) Length of Cleaning Time–
5 to 10 minutes
...Not more than 15 minutes.
4) Care must be taken
not to score
the tube (liner) with the nozzle or wand end.
5) Prolonged steam jet contact on a specific area of the tube (liner)
could cause tube damage
.
