4-Vinylpyridine in Resins

4-Vinylpyridine (4VP) finds industrial use in resins. It can be used in precious metal recovery and in ion exchange applications. 

Vinylpyridines provide a unique set of properties to wide range of applications due to good thermal stability, chemical stability, mild basicity, mild pH trigger, and compatibility with most polymerization techniques.


Precious Metal Recovery

Precious metals are rare, naturally occurring metallic chemical elements. Precious metals tend to be less reactive than most elements. Examples are gold, silver, platinum, and palladium. Chemically stable and effective in strong acids, 4VP-based resins are effective in metal recovery, mining, refining, and purification. 

Ion Exchange Resins

4-Vinylpyridine based resins have unique properties due to the pyridine ring and resin’s strong interactions with polar and aromatic materials that enable their removal from liquid and gaseous process streams. The chemical and thermal stability of the resin gives utility in a wide range of ion exchange applications.
