WebUrethane's resistance to chemicals is affected by the chemical's concentrations, temperature and duration of contact with the urethane. Unless otherwise noted, the chemicals listed below are at full concentration and 70°F . A = Little or no effect B = Minor to mderate effect C = Severe effect WebRaffinate. In chemical separation terminology, the raffinate (from French raffiner, to refine) is a product which has had a component or components removed. The product having the removed materials is referred to as the extract. For example, in solvent extraction, the raffinate is the liquid stream which remains after solutes from the original ...
