Epoxy: Manufacturing Process & Applications - Plastics …

In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen. This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers. They are produced on a large scale for many applications. In general, low molecular weight epoxides are colourless and nonpolar, and often volatile. WebJan 2, 2015 · At a 1:1 weight ratio, there is an excess of epoxy compared to mercaptan groups.
