Cov polypropylene (PP) resins yog cov thermoplastic polymers, txhais tau tias lawv yuav raug tsim los ntawm cua sov thiab rov yaj yam tsis poob lawv cov yam ntxwv intrinsic. Thermoplastics txawv ntawm txoj kev no los ntawm thermosets, uas hloov pauv tas mus li tom qab hardening. Thermoplastics feem ntau yog recyclable rau qhov laj thawj no. Lwm cov thermoplastics suav nrog polyethylene, polyvinyl chloride, polystyrene, polycarbonate, acrylic, acrylonitrile butadiene styrene, nylon, thiab polytetrafluoroethylene.
Cov polypropylene resins feem ntau yog cov polymers uas tsis pom tseeb, tsis muaj zog nrog cov yam ntxwv zoo heev rau thermoforming thiab txhaj tshuaj molding. Piv nrog rau lwm cov polymers, cov khoom siv no muaj qhov kub thiab txias nqaim, ua rau brittle hauv qab -20 ° C thiab siv tsis tau hauv qhov kub tshaj 120 ° C. Nws sib tw feem ntau nrog polyethylene thiab tuaj yeem ua kom pom tseeb rau cov khoom xws li cov pob khoom pom tseeb, thaum polyethylene tsuas yog ua kom pom tseeb, xws li hauv cov jugs mis nyuj, piv txwv li. Polypropylene tsis tuaj yeem phim qhov pom tseeb ntawm cov polymers xws li polycarbonate tab sis nws ua tau zoo heev.
Cov polypropylene homopolymers thiab polypropylene copolymers ua rau feem ntau ntawm cov polypropylene formulations niaj hnub no. Homopolymer yog qib siv dav dav, muaj ib qho propylene monomer, thiab yog semi-crystalline hauv daim ntawv. Muaj ntau yam copolymers muaj, uas, thaum piv rau homopolymer, muaj kev mos mos dua, tiv taus kev cuam tshuam zoo dua, ruaj khov dua thiab tawv dua, txhim kho lub zog qis qis, thiab tiv taus kev tawg zoo dua. Qib siv dav dav yog qhov pom zoo rau kev sib cuag zaub mov thiab daim ntawv thov qhov twg qhov tawv yog qhov tseem ceeb. Qee qhov kev sib xyaw ntawm co- thiab homopolymers ua rau cov ntaub ntawv uas muaj lub zog cuam tshuam siab (PP cuam tshuam copolymer); lossis, sib xyaw nrog ethylene thiab butane, cov khoom zoo dua-sealing zaj duab xis (PP terpolymer); lossis cov khoom siv kho tshuab zoo dua xws li lub zog yaj thiab extensibility (PP HMS). Polypropylene muaj nyob rau hauv daim ntawv nthuav dav, qis-density, kaw-cell ua npuas ncauj (EPP).
Qhov kub qis ntawm Polypropylene ua rau nws nyuaj rau tshuab thiab tsis tau ua dab tsi los tsim cov filaments uas haum rau 3D printing. Txawm li cas los xij, nws cov viscosity qis ntawm qhov kub yaj ua rau nws zoo rau extrusion thiab molding daim ntawv thov, suav nrog blow molding, compression molding, thiab rotomolding, piv txwv li.
Tsis zoo li ntau cov thermoplastics, polypropylene tsis yooj yim nqus cov dej noo, thiab nyob rau hauv ib txwm muaj xwm txheej feem ntau tuaj yeem pwm yam tsis tau raug thawj zaug rau lub voj voog ziab.

Kev siv propylene tseem ceeb tuaj yeem muab faib ua tsib pawg: PP txhaj tshuaj molding, PP kos duab, PP fiber, PP zaj duab xis, PP yeeb nkab.
1. PP txhaj tshuaj molding
PP yas feem ntau yog siv rau hauv cov khoom siv hauv tsev me me, cov khoom ua si, cov tshuab ntxhua khaub ncaws, cov khoom siv hauv tsheb thiab lwm yam.
2. PP hlau kos duab
Cov khoom siv kos duab polypropylene feem ntau yog siv rau hauv cov khoom yas woven, kev siv txhua hnub ntawm cov hnab ntim khoom, cov hnab woven, cov hnab zaub mov thiab cov hnab pob tshab yog cov khoom siv kos duab PP.
3. PP zaj duab xis
Feem ntau, cov yeeb yaj kiab polypropylene muab faib ua BOPP zaj duab xis, CPP zaj duab xis, IPP zaj duab xis, thiab PP zaj duab xis feem ntau yog siv rau hauv cov khoom noj khoom haus.
4. PP fiber
Polypropylene fiber yog ib hom khoom siv fiber ua los ntawm polypropylene los ntawm kev sib hloov yaj. Feem ntau siv rau hauv kev kho kom zoo nkauj, khaub ncaws thiab lwm yam teb, txij li thaum siv txoj cai ob tug menyuam hauv xyoo 2011, cov ntaub so ntub dej, cov ntaub so ntswg thiab lwm yam khoom niam thiab menyuam yaus nce ntxiv, ua rau cov khoom siv fiber hauv tsev tsis txaus.
5. Cov yeeb nkab PP
Vim yog polypropylene tsis muaj tshuaj lom thiab kub tsis kam, PP yeeb nkab feem ntau yog siv rau hauv kev muab dej thiab cua sov, piv rau PE yeeb nkab, PP yeeb nkab hnyav yog sib dua, yooj yim thauj mus los, thiab kev tiv thaiv ib puag ncig zoo dua, tuaj yeem rov ua dua tshiab.
Cov ntim khoom yog nyob rau hauv 25kg hnab yas, uas tuaj yeem thauj los ntawm kev tsheb ciav hlau lossis hiav txwv thiab khaws cia rau hauv lub tsev rau khoom qhuav.
