Sodium polysulphide Letter 1109 --- I'm on the staff of a research group attempting to assemble an economic model for one of McDonnell Douglas' helicopter manufacturing facilities. The model is almost complete, but I am having an extremely hard time finding a manufacturer/ price for the chemical sodium polysulfide, if anybody has any relevant information. Thanks, DJ Wiegand, Chem. E. -Michigan Technological University --- I am having a hard time understanding where sodium polysulfide is used in the manufacture of helicopters. Perhaps in waste treatment? If so, check with the supplier! Ask the guys who gave you the list of chemicals they're using. I do know you can get sodium polysulfide from most lab supply houses. Check your Mallinkrodt, J.T. Baker, Merck, or equivalent catalog. Bill Vins microwave & cable assemblies Mesa (what a place-a), Arizona

I am also looking for polysulfide solutions,both sodium and ammonium, I have managed to source sodium tetrasulfide in an ALFA (Johnson Matthey ) catalog,but have had no luck with any pentasulfides.

Can any one help!!!

Thanks

I had also some trouble in finding commercially available sodium polysulfide. I went back in the chemical history of polysulfide sealing compounds. They are produced from liquid polysulfides for example by Morton International.

Morton Int. is using sodium polysulfide as intermediate in their production but it usually will not be isolated.

I found a second source, also a producer of liquid polysulfides.

I can think of two applications for polysulfides in the metal finishing industry.

1. It is used as an additive in zinc cyanide solutions to overcome metallic impurities. If this is the case, any supply house of brighteners for the zinc solutions will sell you polysulfide under commercial names.

2. It is used for testing protective layers of silver deposits. In this case, the quantities you need are very small and you can probably get it from fine chemical suppliers like Sigma, Merck etc.

Sodium Polysulfide is available from Best Sulfur Products in Fresno, CA. I came across this question on Google and was brought to this site with the link provided. I hope this helps.

Any suggestions as to off the shelf sources of supply in Europe. I want to use the product short term to detox small amounts of laboratory cyanide wastes until such time as these wastes can be returned to the mine circuits once the mine is commissioned in about 3 months time.

++++ Most plating supply houses will probably have this in stock since it is used for the several purposes previously mentioned. While it may be used as a final precipitant, though, I have never heard of detoxing cyanide with sodium polysulphide. Ted Mooney finishing.com Brick, New Jersey April 8, 2008 Alan Massey, Mobile Al offered to supply an MSDS for sodium polysulfide. How do we contact Mr. Massey? Walter Lydick - Jackson, Mississippi February 11, 2009 Dear readers: I am the Plant Engineer for a production unit who manufactures Sodium Polysulfide. In fact, I am Alan Massey's replacement! I would be happy to provide MSDS, product and customer service information for our product. Sincerely, JONAH KLEIN Evonik-Degussa - Mobile, Alabama opt
