The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).

The global epoxy resin market was valued at approximately $8 billion in 2016. The epoxy resin market is dominated by the Asia-Pacific region, which contributes 55.2% of the total market share. China is the major producer and consumer globally, consuming almost 35% of the global resin production.
Envalior (formerly DSM) is the only commercial supplier of this resin, which markets under the trade name Stanyl. [ 1 ] [ 2 ] Nylon 46 is an aliphatic polyamide formed by the polycondensation of two monomers , one containing 4 carbon atoms, 1,4-diaminobutane ( putrescine ), and the other 6 carbon atoms, adipic acid , which give nylon 46 its name.
A resin is a solid or highly viscous liquid that can be converted into a polymer. [1] Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, and predominantly terpenes. Well known resins include amber, hashish, frankincense, myrrh and the animal-derived resin, shellac.
Bakelite was produced for the first time in 1872 by Adolf von Baeyer, though its use as a commercial product was not considered at the time. [6]Leo Baekeland was already wealthy due to his invention of Velox photographic paper when he began to investigate the reactions of phenol and formaldehyde in his home laboratory.

A melamine-resin plate A melamine-resin ladle. Melamine resin is often used in kitchen utensils and plates (such as Melmac). Because of its high dielectric constant ranging from 7.2 to 8.4, melamine resin utensils and bowls are not microwave safe. [3] During the late 1950s and 1960s melamine tableware became fashionable.
