Phenol-formaldehyde resins What is Chemistry

Phenol-formaldehyde resins These thermosetting resins are obtained by reacting phenol C 6 H 5 OH and phormaldehyde CH 2 O. Formaldehyde forms −CH 2 − bridges between two phenol molecules, producing chains. Linear chains are obtained when the reaction ratio is 1:1. Phenol, however, may also react with a third formaldehyde molecule.
