Fenolformaldehyde
Phenol formaldehyde is a thermosetting polymer, also known as Bakelite or Novolac. It is formed by the reaction of phenol with formaldehyde, typically under acidic or basic conditions. This reaction creates a cross-linked network structure, which gives the material its characteristic rigidity and thermal stability.
The polymerization process can be controlled to produce different types of resins. Resols, formed under alkaline
Phenol formaldehyde resins exhibit excellent electrical insulation properties, good heat resistance, and mechanical strength. They are
Historically, phenol formaldehyde was one of the first synthetic plastics to be mass-produced and found widespread
