Polypropylene (PP) resins o polymers thermoplastic, o lona uiga e mafai ona fausia i le vevela ma toe liusuavai e aunoa ma le aveesea o latou uiga taua. Thermoplastics eseese i lenei auala mai thermosets, lea e oʻo i suiga tumau pe a maeʻa. Thermoplastics e masani ona toe fa'aaogaina mo lea mafua'aga. O isi mea fa'afefete e aofia ai le polyethylene, polyvinyl chloride, polystyrene, polycarbonate, acrylic, acrylonitrile butadiene styrene, nylon, ma le polytetrafluoroethylene.
Polypropylene resins e masani lava opaque, maualalo-density polymers ma sili thermoforming ma tui tui uiga. Pe a faatusatusa i isi polymers, o le meafaitino o loʻo i ai se vaapiapi vaʻaia o le vevela, maʻaleʻale i lalo -20°C ma e le mafai ona faʻaaogaina i le vevela i luga atu o le 120°C. E tauva muamua i le polyethylene ma e mafai ona faʻamalamalamaina mo mea e pei o pusa vaʻaia, ae o le polyethylene e mafai ona faʻafefeteina, pei o fagu susu, mo se faʻataʻitaʻiga. E le mafai e le Polypropylene ona fetaui ma le manino manino o polymers e pei ole polycarbonate ae e lelei tele.
Polypropylene homopolymers ma polypropylene copolymers o loʻo faia ai le tele o faʻasologa o polypropylene i aso nei. O le homopolymer o le vasega fa'aoga lautele, e aofia ai se monomer propylene tasi, ma e semi-crystalline i foliga. O lo'o maua le tele o copolymers, lea, pe a fa'atusatusa i le homopolymer, ua fa'atuputeleina le malu, sili atu le tete'e o a'afiaga, sili atu le tumau ma le ma'a'a'a, fa'aleleia atili le malosi o le vevela, ma sili atu le tete'e. O le fa'aoga lautele o le togi lea e fautuaina mo le fa'afeso'ota'i o mea'ai ma fa'aoga e taua ai le malo. O nisi fa'afefiloiga fa'atasi ma homopolymers e maua ai mea e maualuga lona malosi (PP impact copolymer); po'o, fa'afefiloi ma le ethylene ma le butane, mea fa'amaufa'ailoga sili atu (PP terpolymer); po'o le fa'aleleia atili o mea fa'ainisinia e pei ole malosi fa'afefeteina ma fa'alautele (PP HMS). O lo'o maua le Polypropylene e pei o se fa'alaua'itele, la'ititi-maualalo, tapuni-cell foam (EPP).
O le maualalo o le vevela o le polypropylene e faigata ai le masini ma e itiiti se mea na faia e gaosia ai filaments e fetaui ma le lomitusi 3D. Ae ui i lea, o lona viscosity maualalo i le vevela vevela e fetaui lelei i le extrusion ma le faʻaogaina o talosaga, e aofia ai le faʻafefe, faʻamalosi faʻamalosi, ma le rotomolding, mo se faʻataʻitaʻiga.
E le pei o le tele o thermoplastics, o le polypropylene e le faigofie ona mitiia le susu, ma i lalo o tulaga masani e masani lava ona faʻapipiʻiina e aunoa ma le faʻaogaina muamua i se taamilosaga faʻamago.

O le faʻaaogaina autu o le propylene e mafai ona vaevaeina i ni vaega se lima: PP tui faʻapipiʻi, PP ata, PP fiber, PP ata, PP paipa.
1. PP tui tui
PP palasitika e masani ona faʻaaogaina i mea laiti fale, meataalo, masini fufulu, vaega taʻavale ma isi.
2. PP uaea ata
O le tusi uaea Polypropylene e masani lava ona faʻaaogaina i oloa lalaga palasitika, o le faʻaaogaina i aso uma o taga pusa, taga lalaga, taga meaʻai ma taga manino o oloa PP uaea tusi mea.
3. PP ata tifaga
Polypropylene ata tifaga e masani ona vaevaeina i le BOPP ata tifaga, ata CPP, ata tifaga IPP, PP ata tifaga e masani ona faʻaaogaina i meaʻai afifiina.
4. alava PP
O le alava polypropylene o se ituaiga o oloa fiber e faia mai le polypropylene e ala i le liusuavai. E masani ona faʻaaogaina i teuteuga, lavalava ma isi fanua, talu mai le faʻatinoina o le faiga faʻavae e lua-tamaiti i le 2011, solo susu susu, napekini ma isi oloa a tina ma pepe, faʻalavelave faʻafuaseʻi tuʻuina atu o meafaitino.
5. PP paipa
Ona o le le oona ma le maualuga o le vevela tetee o le polypropylene, o mea paipa PP e masani ona faʻaaogaina i le tuʻuina atu o le vai ma le faʻavevelaina, pe a faʻatusatusa i le paipa PE, o le mamafa o le paipa PP e mama, felauaiga faigofie, ma sili atu le lelei o le puipuiga o le siosiomaga, e mafai ona toe faʻaaogaina. .
O le faʻapipiʻiina o loʻo i totonu o le 25kg taga palasitika, e mafai ona feaveaʻi e ala i nofoaafi poʻo le sami ma teu i totonu o se faleteuoloa mago.
