Teflon FEP is translucent, flexible and feels heavy because of its high density. It resists all known chemicals except molten alkaki metals, elemental fluorine and fluorine precursors at elevated temperatures. It should not be used with concentrated perchloric acid. FEP withstands temperatures from -270 degrees C to +250 degrees C and may be sterilized repeatedly by all known chemical and thermal methods. It can even be boiled in nitric acid.
