PHENOLIC RESINS PROPERTIES Excellent dielectric strength Good machinability Light weight Heat and wear resistant Resists corrosion and chemicals Good mechanical strength & dimensional stability Low moisture absorption APPLICATONS Terminal boards Switches Bearings Gears Wear strips Gaskets Washers Transformers Machining components Industrial laminates bagpipe chanters... Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.

Why phenol does not dissolve in water when excess?

Phenol is slightly soluble in water due to hydrogen bonding between the hydroxyl group of phenol and water molecules. However, when excess phenol is added, it disrupts the hydrogen bonding network of water molecules, making it less soluble. This is because phenol-phenol interactions become stronger than phenol-water interactions, leading to precipitation.
