Fa'afefea ona Filifili Mea Fa'akomepiuta Sili Mo le Fa'a'au'au Fa'apalapala
Filifilia o le palasitika saʻo mo le faʻapipiʻiina o tui palasitika e mafai ona faigata-e i ai le faitau afe o filifiliga i le maketi e filifili mai ai, o le tele o ia mea e le aoga mo se sini. O le mea e laki ai, o le malamalama loloto i meafaitino manaʻomia ma le faʻaogaina o le a fesoasoani e faʻaitiʻitia le lisi o filifiliga e mafai ona faʻaogaina i se mea e sili atu ona faʻaogaina. Pe a iloiloina le talosaga, e taua le manatua o fesili nei:
O fea o le a faʻaaogaina ai le vaega?
O le a le umi o lona ola galue?
O a fa'amamafa o lo'o aofia i le fa'aoga?
E iai se sao o mea fa'alelei, pe o le fa'atinoga e sili ona taua?
O a ni fa'alavelave tau tupe i le talosaga?
I se tulaga talitutusa, o fesili o loʻo i lalo e aoga pe a filifilia mea e manaʻomia:
O a uiga fa'ainisinia ma vaila'au e mana'omia mai le palasitika?
E fa'afefea ona amio le palasitika pe a fa'avevela ma mālūlū (fa'ata'ita'iga, fa'alauteleina o le vevela ma fa'aitiitia, fa'afefeteina le vevela, vevela fa'aleagaina)?
O a fegalegaleaiga a le palasitika ma le ea, isi palasitika, vailaʻau, ma isi?
O lo'o aofia ai i lalo se laulau o palasitika fa'apipi'i masani, ta'itasi ma ana lava seti o mea lelei ma fa'aoga lautele o alamanuia:

Thermoplastics o le filifiliga sili lea mo le tui tui. Mo le tele o mafuaʻaga e pei o le toe faʻaaogaina ma le faigofie o le gaosiga. O fea la e mafai ona fa'aogaina ai se oloa e fa'aoga ai le vevela, alu i ai. O oloa fa'alelei maualuga mo le umi na mana'omia ai le mana'omia mo elastomers thermoset. O aso nei e te maua le filifiliga o elastomers thermoplastic. Ina ia matua fetuutuunai lau vaega e le aveesea ai le filifiliga o le faʻaaogaina o thermoplastics. E iai fo'i togi 'ese'ese o TPE mai le vasega o mea'ai e o'o atu i TPE maualuga.
O palasitika oloa e fa'aaogaina i oloa fa'atau i aso uma. O fa'ata'ita'iga o ipu kofe polystyrene, ipu e ave ai le polypropylene, ma tapuni fagu polyethylene maualuga. E taugofie ma tele avanoa. E fa'aaogaina palasitika fa'ainisinia, e pei ona ta'u mai e le igoa, fa'ainisinia. E te mauaina i totonu o greenhouses, ie taualuga, ma meafaigaluega. O faʻataʻitaʻiga o polyamides (Nylon), polycarbonate (PC), ma le acrylonitrile butadiene styrene (ABS). E mafai ona latou tatalia tulaga faigata o le siosiomaga. O le a latou tatalia le uta ma le vevela e sili atu nai lo le vevela o le potu. O palasitika maualuluga e fa'atino lelei i lalo o tulaga e fa'aletonu ai oloa ma palasitika fa'ainisinia. O faʻataʻitaʻiga o palasitika maualuga faʻatinoga o le polyethylene ether ketone, polytetrafluoroethylene, ma le polyphenylene sulfide. E taʻua foi o le PEEK, PTFE, ma le PPS. Latou te maua le faʻaogaina i luga o faʻaoga maualuga e pei o le aerospace, masini faʻafomaʻi, ma masini. O le maualuga o le faatinoga e sili atu le taugata nai lo se oloa poʻo se palasitika inisinia. O meatotino o palasitika e fesoasoani ia te oe e filifili po o fea e fetaui ma se faʻaoga faapitoa. Mo se faʻataʻitaʻiga, o nisi tusi talosaga e manaʻomia mea malolosi ae mama. Mo lenei mea, e te faʻatusatusaina lo latou mamafa ma le malosi tensile.
