Thermosets
Phenolic Novolac Thermoset — Phenolic Novolac Resin
Phenolic novolac resins are thermosets formed by reacting phenol with excess formaldehyde under acidic conditions. They offer excellent thermal stability, flame retardancy, and good mechanical properties, often compounded with fillers for specific uses.
