Function of Epoxol® 9-5

The activity of Epoxol® 9-5 as a plasticizer acid scavenger and reactive chemical intermediate is due to its high oxirane content (9% minimum), an average of 5-1/2 groups per molecule. It is capable of reacting with 5-1/2 equivalents of mineral acid, halogen acid, or carboxylic acid. The stronger and more corrosive the acid, the more rapidly it is deactivated by Epoxol® 9-5. The epoxy groups in Epoxol® 9-5 open in the presence of acids and chemically combine to form neutral esters of the acid present. (Epoxol® 9-5 and its reaction products with acids are neutral.)

Epoxol® 9-5 contains 30% more oxirane oxygen than Epoxidized Soybean Oil and therefore, 30% more functionality on an equal weight basis. This will result in greater performance and/or efficiency when used at the same percentage in a formula.
