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).

Cost-push inflation is a purported type of inflation caused by increases in the cost of important goods or services where no suitable alternative is available. As businesses face higher prices for underlying inputs, they are forced to increase prices of their outputs. It is contrasted with the theory of demand-pull inflation.
As an Epoxy modifier it is classed as an epoxy reactive diluent. [8] It is also used to synthesize other molecules. [9] The use of the diluent does effect mechanical properties and microstructure of epoxy resins. [10] [11] It has been used to simultaneously increase cryogenic strength, ductility and impact resistance of epoxy resins. [12]

The 2000s commodities boom, commodities super cycle [1] or China boom was the rise of many physical commodity prices (such as those of food, oil, metals, chemicals and fuels) during the early 21st century (2000–2014), [2] following the Great Commodities Depression of the 1980s and 1990s.
