Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs Discovered in 1907 by Leo Baekeland and sold as Bakelite in 1909, phenol formaldehyde resin was the first true synthetic plastics. We use cookies to help provide and enhance our service and tailor content and ads. Phenol-formaldehyde resins were the first completely synthetic polymers to be commercialized. The boards are constituted of a relatively incoherent material, pasted by a phenol resin acting as a glue. Phenol-formaldehyde polymers are polymers formed by the interaction of a phenol, or a mixture of phenols, and formaldehyde. Phenolic resins (Phenoplasts) are synthetic thermosetting resins invented by Dr. Leo Baekeland in 1907. Phenolic resins are a group of the most versatile polymers yet invented. They may be used in this state or an organic solvent such as methanol can be added to reduce the solids concentration and viscosity of the mixture. background: white; Cracking, discoloration, fading, blooming. padding: 1px; .slideritem { .slidergallery_leftalign { }, Physical Properties for Selected Thermoset Resins.
