phenoplast

A scientist pours phenoplast resin into a mold.

Definition

Noun: A synthetic thermosetting resin produced by the condensation of a phenol with an aldehyde, especially formaldehyde. Phenoplasts are characterized by their hardness, chemical resistance, and electrical insulating properties once cured. They are a type of plastic.

Usage

Phenoplast is used as a material noun. It refers to the class of resinous materials themselves, not typically to a single object made from them. * The early electrical insulators were made from phenoplast. * Phenoplast is known for its excellent heat resistance. * The chemist developed a new formula for the phenoplast.

Examples
  • The laboratory tabletop was coated with a durable layer of phenoplast.
  • One of the first synthetic plastics, Bakelite, is a type of phenoplast.
  • The properties of the phenoplast make it suitable for automotive components.
Advanced Usage
  • As an uncountable noun: Most commonly, "phenoplast" is used as an uncountable noun referring to the substance in bulk or as a material.
    • The mold was filled with liquid phenoplast.
  • In technical/industrial contexts: The term is primarily used in scientific, engineering, and manufacturing discussions about materials.
    • The study compared the mechanical strength of phenoplast to that of epoxy resins.
Variants and Related Words
  • Phenolic resin: This is a more common technical synonym for phenoplast.
  • Phenol-formaldehyde resin: This is the specific chemical name for the most common type of phenoplast.
  • Thermoset / Thermosetting plastic: This is the broader category to which phenoplasts belong. Once cured, they cannot be remelted.
  • Bakelite: This is a historical and trademarked name for an early and well-known type of phenoplast.
Synonyms
  • Phenolic resin
  • Phenol-formaldehyde resin
  • Thermosetting phenolic
