Resins are polymer made by repeatedly linking discrete molecules (monomers) together to form chain or networks. Plenco phenolic resins are oligomers (polymers with a few repeating units) synthesized by repeatedly linking phenolic (hydroxy-aromatic) monomers with aldhehyde chemicals.
The majority of Plenco products are combinations of phenol (hydroxybenzene, C6H6O) and formaldehyde (methanal, CH2O), though specialized applications may require use of substituted phenols (such as, cresol, resorcinol, cashew, nutshell liquid distilate), or other aldhehydes. Phenolic resin manufacturers polymerize phenol by substituting formalin on the phenol's aromatic ring via a condensation reaction.
