phapang pakeng tsa PP le PVC ho sa tsotellehe ponahalo kapa maikutlo a ka fapana haholo;Boikutlo ba PP bo batla bo le thata 'me PVC e batla e le bonolo.
PP ke resin ea thermoplastic e lokiselitsoeng ke polymerization ea propylene.Ho na le litlhophiso tse tharo tsa lihlahisoa tsa isochronous, tse sa laoloang le tse fapaneng, 'me lihlahisoa tsa isochronous ke likarolo tse ka sehloohong tsa lihlahisoa tsa indasteri.Polypropylene e boetse e kenyelletsa li-copolymers tsa propylene le palo e nyane ea ethylene.Hangata e translucent, e se nang 'mala e tiileng, e sa nkhang ha e sa chefo.
Likarolo: e seng chefo, e sa latsoeheng, e tlaase, matla, ho tiea, ho thatafala le ho hanyetsa mocheso ho molemo ho feta polyethylene e tlaase ea khatello, e ka sebelisoa ka likhato tse 100 kapa joalo.Thepa e ntle ea motlakase le li-insulation tse phahameng tsa maqhubu ha li amehe ke mongobo, empa li fetoha brittle ka mocheso o tlase, ha li senyehe, li bonolo ho tsofala.E loketse ho etsa likarolo tse akaretsang tsa mochini, likarolo tse hanyetsanang le kutu le likarolo tsa insulation.
PVC ke e 'ngoe ea lihlahisoa tse kholo ka ho fetisisa lefatšeng tsa lihlahisoa tsa polasetiki, tse theko e tlaase, tse sebelisoang haholo, polyvinyl chloride resin ke phofo e tšoeu kapa e bobebe e mosehla.Li-additives tse fapaneng li ka eketsoa ho latela li-USES tse fapaneng, 'me lipolasetiki tsa polyvinyl chloride li na le thepa e fapaneng ea' mele le ea mochini.Ho eketsa polasetiki e nepahetseng ka polychlorethylene resin e ka etsoa ka mefuta e fapaneng ea lihlahisoa tse thata, tse bonolo le tse hlakileng.Boima ba PCC e hloekileng ke 1.4g/cm3, 'me bongata ba li-plasticizers le li-filler tsa PCC hangata ke 1.15-2.00g/cm3.POLYchlorethylene e thata e na le matla a matle, a tenyetsehang, a hatellang le a ho hanyetsa 'me e ka sebelisoa e le thepa ea meralo feela.
