Why Process Industries Want PSP® Fume Exhaust Duct

Posted by Mike Baranski on May 1, 2018 3:20:15 PM

Fluoropolymer Coating and Stainless Steel Fume Exhaust Duct Are a Perfect Combination 

There's no shortage of corrosive fumes and vapors generated by process industries which need to be safely and successfully vented.

Common exhaust duct materials that are tasked with this responsibility include stainless steel, polyvinyl chloride (PVC), and fiberglass reinforced plastic (FRP). While special glass linings, metal alloys, and a wide range of polymers may be used individually or in combination to help meet particular demands, none seem to solve the breadth of corrosive application challenges like PermaShield Pipe (PSP®) with its proprietary fluoropolymer coating.

Fluoropolymer Coating - Q&A

What is a fluoropolymer? A fluoropolymer is a fluorocarbon-based substance that contains atoms of fluorine. It is characterized by a high resistance to solvents, acids, and bases. Fluoropolymers were discovered by happen-stance in 1938 by Dr. Roy J. Plunkett as he was working on freon (for the DuPont corporation) and accidentally polymerized tetrafluoroethylene.

The result was PTFE (polytetrafluoroethylene), more commonly known as Teflon. This material was found to have the lowest coefficient of friction of any known solid and was inert to virtually all chemicals known. Its corrosion resistivity (in almost all applications) exceeds that of glass (borosilicate and enameled glass-steel) and exotic alloys such as Hastelloy, Niobium, Tantalum and Titanium.
