fenolihartsilla
Fenolihartsilla, commonly referred to as phenolic resin, is a class of synthetic polymers produced by the condensation of phenol with formaldehyde. These resins are typically thermosetting, meaning that once cured they form crosslinked networks that are resistant to heat, chemicals, and creep. The term encompasses several closely related resins developed in the early 20th century, including the well-known Bakelite.
The two main families of phenolic resins are novolacs and resols. Novolacs are formed with phenol and
Manufacture involves acid- or base-catalyzed condensation polymerization of phenol with formaldehyde, producing water as a byproduct.
Applications are diverse and historically significant. Phenolic resins are used in electrical insulation components, moulded thermoset
Safety and environmental aspects focus on residual formaldehyde emissions and handling hazards associated with phenol and
