Cardanol is a naturally occurring Phenol manufactured from CNSL. It is a monohydroxyl Phenol having a long hydrocarbon Chain (C15H27) in the meta position. Cardanol is obtained in the distilation process of technical CNSL under reduced pressure. The composition of Cardanol contains approximately 78% of cardanol, 8% cardol, 2% polymeric material, less than 1.2% methyl cardanol, 2.3% heptadecyl homologue triene, 3.8% heptadecyl homologue diene and the remainder other homologous phenols. Cardanol contributes to improved flexibility, good drying after baking, high electric insulation properties and thermal stability.These properties make Cardanol an effective substitute for the petroleum-based Phenol.
