Meatotino tau vailaau:

Phenol-formaldehyde resin ua saunia e faapea:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
Tasi-Laasaga Resins.Ole fua faatatau ole formaldehyde ile phenol e lava lona maualuga e fa'ataga ai le faiga o le thermosetting e fai e aunoa ma le fa'aopoopoina o isi fa'apogai o feso'ota'iga.
Resin Vaega Lua.Ole fua ole formaldehyde i le phenol e lava le maualalo e taofia ai le faʻafefe o le vevela mai le tupu i le taimi o le gaosiga o le resini.I le taimi lea, ua taʻua le resin novolac resin.Mulimuli ane, o le hexamethylenetetramine o loʻo tuʻufaʻatasia i totonu o le meafaitino e galue ai o se puna o fesoʻotaʻiga vailaʻau i le taimi o le faʻaogaina o le gaioiga (ma le liua i le thermoset poʻo le setete faʻamalolo).

Talosaga:

Phenolic resins o loʻo faʻaaogaina mo vaega taugofie e manaʻomia ai mea lelei faʻamalo eletise, faʻafefe vevela, poʻo vailaʻau.Ole averesi ole ola ole resini e tusa ma le 1 masina ile 21.1°C.E mafai ona fa'alautele lea mea ile teuina ile pusaaisa ile 1.6 i le 10°C.O le fesuiaiga o le faʻamalosi (e tusa ai ma le mafiafia o le lafo) ma faʻatupuina le vevela faʻamalolo i le 93 ° C o le a suia ai le taimi faʻamalolo mai le umi o le 8 itula i le puʻupuʻu 15 min.
O nisi fa'aitiitiga e tupu i le fa'auma mae'a (0.012 i le 0.6 mm / mm), fa'atatau i le aofa'i o le fa'atumu, aofa'i o fa'amamafa, ma le fua o le fofo.Ole taamilosaga vave ole fofo e maua ai le maualuga ole fa'aitiitia.Talu ai e mafai ona fa'avavevave le taamilosaga fa'amalolo, o lo'o fa'aaogaina phenolics i gaioiga pupuu.
E faigofie ona aveese vaega phenolic lafo mai le limu pe afai o loʻo faʻaaogaina vaega vavae e fautuaina e le faʻatau.O le fa'ailoga e fa'aleleia atili ai mea taua o le fa'au'uga mae'a.
