An inhibitor is a chemical that is added to a material to slow down or prevent an unwanted reaction such as polymerization. Inhibitors are added to many materials that can polymerize easily when they are pure. Inhibitor levels in materials may gradually decrease during storage even at recommended temperatures.ther chemicals (catalysts and initiators) and controlled amounts of heat, light and pressure are often involved. Vigorous polymerization is potentially hazardous because the reaction may get out of control. Once started, the reaction is accelerated by the heat that it produces.
