For Fume Exhaust Systems

Polypropylene is an excellent material for fume exhaust systems. It is preferred for systems that are cleaning nitric/hydrofluoric acid fumes. Unlike fiberglass, it is resistant to hydrofluoric acid fumes.

Polypropylene is easily formed into ductwork, scrubbers, etc. It is used for dampers, mist eliminators, packing, piping, and other standard parts.
