Phenoplasts
Phenoplasts, also known as phenolic resins, are a class of synthetic polymers produced by the reaction of phenol with formaldehyde. These thermosetting resins are known for their excellent thermal stability, electrical insulating properties, and resistance to chemicals and solvents. The polymerization process involves a condensation reaction where water is eliminated as a byproduct. There are two main types of phenoplasts: novolacs, which are formed under acidic conditions and require a curing agent, and resols, which are formed under basic conditions and are self-curing.
Phenoplasts find widespread applications in various industries. They are commonly used as binders in the production
