fenoolformaldehüüd
Fenoolformaldehüüd, also known as phenol formaldehyde resin, is a synthetic polymer that results from the reaction between phenol and formaldehyde. This reaction, often catalyzed by either acid or base, creates a thermosetting plastic that undergoes an irreversible curing process when heated.
The initial reaction produces a liquid or solid prepolymer, which can then be molded and heated to
Phenol formaldehyde resins were among the first synthetic plastics to be commercially produced, with Bakelite being
While still in use for certain specialized applications where their unique properties are advantageous, the use
