I am trying to find out if Phosphine is corrosive to PVC. We have an application to run Coaxial cables down a tunnel below a grain Silo where Phosphine is regularly used as a fumigant. Can Anybody help?
FYI - Phosphine is only corrosive to metals.
- Actually, I believe that phosphine may attack certain plastics too, such as nylon, as well as attacking rubbers and plasticisers. You should be safe with polyethylene or polypropylene. Not sure about PVC- maybe, maybe not. Walkerma 17:49, 19 August 2005 (UTC)
Yes phosphine is corrosive to both metals as well as plastics. Howevr, one may avoid its corrosion to plastics for which PH3 may prove dangerous and set fire in the presence of moisture. Hence, minimizing moisture may result in least damage to plastics. Muhammad Shoaib Ahmedani, (Ph.D.) Entomology, University of Arid Agriculture, Rawalpindi, Pakistan.
PH3 is corrosive to metals and to a lesser degree platics. If you are running Coaxial through the bottom of a bin that is regularly fumigated with PH3, is the coaxial sealed airtight within the PVC? If not, you may have corrosion!
