Resin ea phenolicke thepa ea polymer ea maiketsetso e entsoeng ka ho kopana ha li-phenol (tse kang phenol) le aldehydes (tse kang formaldehyde) tlas'a asiti kapa motheo oa catalysis. E na le khanyetso e ntle ea mocheso, ho thibela mocheso le matla a mechini 'me e sebelisoa masimong a motlakase, a likoloi, a lifofane le a mang.
Phenolic resin (Phenolic Resin) ke resin ea maiketsetso e seng e ntse e sebelisoa indastering. E etsoa ke karabelo ea condensation ea phenol kapa lintho tse tsoang ho eona (joalo ka cresol, xylenol) le formaldehyde. Ho ea ka mofuta oa catalyst (e nang le asiti kapa alkaline) le karolelano ea thepa e tala, e ka aroloa ka mekhahlelo e 'meli: thermoplastic le thermosetting.
