The synthetic thermosetting polymers referred to as "bakelite resins," or phenolic resins, were initially created in the early 1900s by Belgian-American chemist Leo Hendrik Baekeland. These resins have been essential to the development of plastics throughout history, and because of their remarkable qualities, they are widely used in a wide range of consumer and industrial applications. Formaldehyde, an aldehyde, and phenol, an aromatic molecule with hydroxyl functional, combine to generate bakelite resins. Bakelite resins are extremely stiff and heat-resistant because of this reaction, known as condensation polymerization, which creates a three-dimensional cross-linked network structure. Because of their resistance to deformation and high temperatures, they are especially useful in applications where other materials, such conventional thermoplastics, would break down. The superior electrical insulating qualities of Bakelite resins are among their main advantages. They have made a substantial contribution to the development of the electrical industry by being widely used in the fabrication of electrical components like switches, plugs, connectors, and circuit boards. Even in demanding electrical applications, their low electrical conductivity and excellent dielectric strength guarantee dependable operation. But over time, the dominance of Bakelite resins has decreased due to the development of alternative polymers and composites. More contemporary materials with better qualities have supplanted many of its initial uses. However, Bakelite is still useful in specialised applications where its special set of qualities is crucial. In conclusion, the world of materials and polymers has been significantly impacted by Bakelite resins. Their creation revolutionised a number of sectors and represented a critical turning point in the development of synthetic polymers and their uses. Bakelite resins are still associated with innovation and the groundbreaking work that established the groundwork for contemporary plastics technology, even though their use is decreasing.
