Phenolic Resin

A Versatile High-Performance Material

Phenolic resin, derived from the reaction between phenol and formaldehyde, is renowned for its exceptional mechanical strength, dimensional stability, and superior thermal stability. This thermosetting resin offers outstanding resistance to electricity, solvents, and acids, making it highly versatile. As a result, phenolic resin is widely used in manufacturing molding compounds, electronic packaging materials, laminating sheets, surface polishing compounds, bonding agents, impregnation processes, casting resins, and other industrial applications.
