PTFE Sheet Style 7000 is made form 100% virgin PTFE. Virgin PTFE is almost universally inert as
a result of the molecular structure of the resin. Components made of this material exhibit excellent impermeability to most corrosive liquids, vapors and gases, even at elevated temperatures, as well as under pressure and vacuum. Virgin PTFE has exceptional electrical and dielectric properties, but can somewhat limited for mechanical applications. It will creep or cold flow when a compressive load is applied.
