Phenolic temperature range
WebNov 20, 2015 · The pre-oxidation temperature was 250 °C, stabilization time was 2 h, heating rate was 5 °C·min −1, the whole pre-oxidation process was maintained in an air atmosphere. The carbonization temperature was 900 °C, carbonization time was 2 h, heating rate was 2 °C·min −1 , the whole process was kept under a nitrogen atmosphere. Phenolic resins are found in myriad industrial products. Phenolic laminates are made by impregnating one or more layers of a base material such as paper, fiberglass, or cotton with phenolic resin and laminating the resin-saturated base material under heat and pressure. The resin fully polymerizes (cures) during this process forming the thermoset polymer matrix. The base material choice depends on the intended application of the finished product. Paper phenolics ar…
