Resins-ka Polypropylene (PP) waa polymers-ka thermoplastic-ka, taasoo la macno ah in lagu samayn karo kulayl oo dib loo dhalaalin karo iyada oo aan la lumin astaamahooda gaarka ah. Thermoplastic-ku sidan ayuu uga duwan yahay thermoset-yada, kuwaas oo isbeddel joogto ah sameeya ka dib marka la adkeeyo. Thermoplastic-yada guud ahaan dib ayaa loo warshadayn karaa sababtan awgeed. Thermoplastic-yada kale waxaa ka mid ah polyethylene, polyvinyl chloride, polystyrene, polycarbonate, acrylic, acrylonitrile butadiene styrene, naylon, iyo polytetrafluoroethylene.
Resins-ka Polypropylene badanaa waa polymers aan caddayn, cufnaan yar leh oo leh astaamo heer-kulul oo heer sare ah iyo qaab-dhismeed duritaan. Marka la barbardhigo polymers-ka kale, walaxdu waxay leedahay heerkul cidhiidhi ah, oo noqda mid jilicsan oo ka hooseeya -20°C isla markaana aan la isticmaali karin heerkulka ka baxsan 120°C. Waxay si weyn ula tartantaa polyethylene waxaana laga dhigi karaa mid hufan oo loogu talagalay walxaha sida baakadaha wax lagu arko, halka polyethylene-ka laga dhigi karo oo keliya mid hufan, sida dhalooyinka caanaha, tusaale ahaan. Polypropylene ma la mid noqon karo cadaynta indhaha ee polymers-ka sida polycarbonate laakiin si fiican ayuu u shaqeeyaa.
Maanta, noocyada polypropylene homopolymers iyo polypropylene copolymers ayaa ah kuwa ugu badan ee loo isticmaalo qaabaynta polypropylene. Homopolymer-ku waa heerka isticmaalka guud, oo ka kooban hal monomer propylene ah, waana qaab nus-kristal ah. Noocyo kala duwan oo copolymers ah ayaa la heli karaa, kuwaas oo, marka la barbar dhigo homopolymer-ka, ay leeyihiin jilicsanaan kordhay, iska caabin saameyn oo wanaagsan, adkeysi iyo adkaansho wanaagsan, kor u qaadid xoog heerkul hooseeya, iyo iska caabin dildilaac wanaagsan. Heerka isticmaalka guud waa kan lagu taliyay taabashada cuntada iyo codsiyada halkaas oo adkaanshuhu muhiim yahay. Isku darka qaarkood ee co- iyo homopolymers waxay keenaan agab leh xoog saameyn sare leh (copolymer saameynta PP); ama, oo lagu qaso ethylene iyo butane, sifooyin filim-xirid oo heer sare ah (PP terpolymer); ama sifooyin farsamo oo la hagaajiyay sida xoogga dhalaalka iyo fidinta (PP HMS). Polypropylene waxaa loo heli karaa xumbo unug xiran oo ballaaran (EPP).
Heerkulka hoose ee daadinta Polypropylene wuxuu adkeynayaa in la farsameeyo, wax yarna lagama qaban soo saarista fiilooyin ku habboon daabacaadda 3D. Si kastaba ha ahaatee, daxalkeeda hooseeya heerkulka dhalaalka ayaa ka dhigaya mid ku habboon isticmaalka daadinta iyo qaabaynta, oo ay ku jiraan qaabaynta afuufidda, qaabaynta cadaadiska, iyo rotomolding, tusaale ahaan.
Si ka duwan thermoplastics-yada badan, polypropylene si fudud uma nuugto qoyaanka, xaaladaha caadiga ahna badanaa waa la qaabeyn karaa iyada oo aan marka hore la marin wareeg qalajin.

Isticmaalka ugu weyn ee propylene waxaa loo qaybin karaa shan qaybood: qaabaynta duritaanka PP, sawirka PP, fiber PP, filimka PP, tuubada PP.
1. wax taajka duritaanka PP
Balaastikada PP waxaa inta badan loo isticmaalaa qalabka guryaha yaryar, alaabta carruurtu ku ciyaarto, mashiinnada dharka lagu dhaqo, qaybaha baabuurta iwm.
2. Sawir silig PP ah
Sawirka siligga Polypropylene waxaa inta badan loo isticmaalaa alaabada balaastikada ah ee la tolay, isticmaalka maalinlaha ah ee bacaha weelka, bacaha tolay, bacaha cuntada iyo bacaha hufan waa alaabada sawirka siligga PP.
3. Filimka PP
Filimka Polypropylene guud ahaan wuxuu u qaybsan yahay filimka BOPP, filimka CPP, filimka IPP, filimka PP waxaa inta badan loo isticmaalaa baakadaha cuntada.
4. Faybarka PP
Faybarka Polypropylene waa nooc ka mid ah badeecadaha faybarka laga sameeyo polypropylene iyadoo la adeegsanayo wareeg dhalaal ah. Inta badan waxaa loo isticmaalaa qurxinta, dharka iyo meelaha kale, tan iyo markii la hirgeliyay siyaasadda laba-ilmoodka ah sannadkii 2011, masaxyada qoyan ee hoos u dhaca, xafaayadaha iyo alaabada kale ee hooyada iyo dhallaanka ayaa kor u kacay, taasoo keentay yaraanta sahayda walxaha faybarka ee gudaha.
5. Tuubada PP
Sababtoo ah iska caabbinta heerkulka aan sunta ahayn iyo heerkulka sare ee polypropylene, walxaha tuubada PP waxaa inta badan loo isticmaalaa nidaamka biyaha iyo kuleylka, marka la barbar dhigo tuubada PE, miisaanka tuubada PP waa mid fudud, gaadiid ku habboon, waxqabadka ilaalinta deegaankana waa ka wanaagsan yahay, dib loo warshadeyn karo.
Baakadu waxay ku jirtaa bacaha balaastikada ah ee 25kg ah, kuwaas oo lagu qaadi karo tareen ama badda laguna kaydin karo bakhaar qalalan.
