Phenolic Resin vs. Epoxy Resin: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 1, 2024
Phenolic resin is a heat-cured polymer made from phenol and formaldehyde, known for heat resistance; epoxy resin is a thermosetting polymer formed from epoxide and polyamine, notable for its strong adhesion and chemical resistance.

Key Differences

Phenolic resin, created by polymerizing phenol with formaldehyde, is known for its high heat resistance and mechanical strength. Epoxy resin, formed from the reaction of epoxide and a polyamine hardener, is recognized for its excellent adhesive properties and durability.
