That would be high density polyethylene, or HDPE. It withstands conc. hydrochloric acid and conc. nitric acid, but for long term storage of sulfuric
acid over 80%, I would go with glass containers. In regards to salts, HDPE resists attack from most common inorganic solids, bar polymerised sulfur
trioxide. As long as you don't mind the containers being translucent or opaque, HDPE is a good, chemical resistant, and less fragile alternative to
glass. It is not, however, suitable for use with most organic solvents. |
