Expanded Polytetrafluoroethylene (PTFE Teflon®), also called expanded Teflon®, is a material that has extremely broad chemical resistance (only molten alkali metals and fluorine gas attack it) and excellent dielectric and non-stick properties.
It is easy to handle and susceptible to degradation by radiation.
Specifically, the Belpaflon PL sheet is made of expanded PTFE and has multidirectional orientation of the fibers.
It is a material with great elasticity and adaptability, very suitable for flanges in poor condition and has the unbeatable chemical resistance of PTFE.
Expanded Teflon is approved by the FDA for food use.
