Polypropylene (PP) resin ndeye thermoplastic polymers, zvichireva kuti inogona kuumbwa nekupisa uye kunyungudutswa zvakare pasina kurasikirwa nehunhu hwayo hwemukati. Thermoplastics inosiyana nenzira iyi kubva kune thermosets, iyo inochinja zvachose mushure mekuoma. Thermoplastics inowanzo shandiswazve nekuda kwechikonzero ichi. Mamwe thermoplastics anosanganisira polyethylene, polyvinyl chloride, polystyrene, polycarbonate, acrylic, acrylonitrile butadiene styrene, nylon, uye polytetrafluoroethylene.
Polypropylene resins anowanzo kuve opaque, yakaderera-density mapolymer ane yakanakisa thermoforming uye jekiseni kuumba maitiro. Zvichienzaniswa nemamwe mapolymer, zvinhu zvacho zvine tembiricha yakati chechetere, ichiva brittle pazasi -20°C uye isingashandisike mukupisa kunodarika 120°C. Inokwikwidza zvakanyanya kupikisa polyethylene uye inogona kuitwa pachena kune zvinhu zvakadai sekuona-kuburikidza nemapakeji, nepo polyethylene inogona kungoitwa translucent, senge mumajagi emukaka, semuenzaniso. Polypropylene haigone kuenderana nekujeka kwemaziso emapolymers akadai sepolycarbonate asi inoita zvakanaka.
Polypropylene homopolymers uye polypropylene copolymers inoumba ruzhinji rwepolypropylene formulations nhasi. Iyo homopolymer ndiyo yakajairika-yekushandisa giredhi, ine imwechete propylene monomer, uye iri semi-crystalline muchimiro. Mhando dzakasiyana-siyana dzemacopolymers dziripo, iyo, kana ichienzaniswa nehomopolymer, yakawedzera kupfava, zviri nani kukanganisa kupikisa, kusimba kwesimba uye kusimba, kuvandudza kushoma-tembiricha simba, uye nani kutsemuka kuramba. Iyo yakawanda-yekushandisa giredhi ndiyo inokurudzirwa yekubata chikafu uye maapplication uko kuoma kwakakosha. Mimwe misanganiswa ye-co- uye homopolymers inoguma mune zvigadzirwa zvine yakakwira simba rekuita (PP impact copolymer); kana, yakasanganiswa ne ethylene uye butane, yepamusoro firimu-sealing properties (PP terpolymer); kana kuvandudzwa kwemagetsi zvinhu zvakadai sekunyunguduka simba uye kuwedzera (PP HMS). Polypropylene inowanikwa seyakawedzera, yakaderera-density, yakavharwa-sero foam (EPP).
Polypropylene's low annealing tembiricha inoita kuti zviome kuchina uye zvishoma zvakaitwa kugadzira filaments inokodzera kudhindwa kwe3D. Nekudaro, iyo yakaderera viscosity pakunyunguduka tembiricha inoita kuti inyatsokodzera kune extrusion uye kuumba maapplication, anosanganisira blow molding, compression molding, uye rotomolding, semuenzaniso.
Kusiyana neakawanda thermoplastics, polypropylene haitore unyoro nyore, uye mumamiriro ezvinhu akajairwa kazhinji inogona kuumbwa pasina kutanga yaiswa pasi pekuomesa.

Iko kushandiswa kukuru kwepropylene kunogona kukamurwa kuita zvikamu zvishanu: PP jekiseni kuumba, PP kudhirowa, PP fiber, PP firimu, PP pombi.
1. PP jekiseni kuumba
PP plastiki inonyanya kushandiswa mumidziyo midiki yemumba, matoyi, muchina wekuwachisa, auto zvikamu uye zvichingodaro.
2. PP wire kudhirowa
Polypropylene waya yekudhirowa inonyanya kushandiswa muzvigadzirwa zvepurasitiki zvakarukwa, kushandiswa kwemazuva ese kwemasaga emidziyo, mabhegi akarukwa, mabhegi echikafu uye mabhegi akajeka ndeye PP waya yekudhirowa zvigadzirwa.
3. PP firimu
Polypropylene firimu rinowanzo kupatsanurwa kuita BOPP firimu, CPP firimu, IPP firimu, PP firimu rinonyanya kushandiswa mukurongedza chikafu.
4. PP fiber
Polypropylene faibha imhando yechigadzirwa chefiber yakagadzirwa kubva ku polypropylene nekunyunguduka kutenderera. Inonyanya kushandiswa mukushongedza, zvipfeko uye mamwe minda, kubvira pakaitwa mutemo wevana vaviri muna 2011, mawipe emvura ezasi, manapukeni uye zvimwe zvigadzirwa zvemadzimai nevacheche zvinowedzera, mudzimba fiber zvinhu kupa kushomeka chiitiko.
5. PP pombi
Nekuda kweiyo isiri-chepfu uye yakanyanya kupisa tembiricha yepolypropylene, PP pombi zvinhu zvinonyanya kushandiswa mukupa mvura uye kudziyisa sisitimu, zvichienzaniswa ne PE pombi, PP pombi huremu huremu, kufambisa kuri nyore, uye kuchengetedza kwezvakatipoteredza kuri nani, kunogona kushandiswazve. .
Kurongedzerwa kwacho kuri mumabhegi epurasitiki anorema 25kg, anogona kutakurwa nechitima kana negungwa ochengetwa mudura rakaoma.
