Phenol + formaldehyde → phenol–formaldehyde polymer (thermosetting)
What each symbol means
| Symbol | What it stands for |
|---|---|
| HCHO | Formaldehyde provides −CH₂− bridges under acidic/basic catalysis |
| Phenol | Aromatic ring with −OH (electrophilic substitution sites ortho/para to OH) |
When to use this
Base or acid catalyzed; excess formaldehyde + heat leads to cross-linked three-dimensional network (thermosetting).
