Nangona i-PP (i-polypropylene) kunye ne-PVC (i-polyvinyl chloride)abahlali beetyhubhu ze-lamellazisetyenziswa kwiinkqubo zokucocwa kwamanzi, kukho umahluko omkhulu kwiipropati zezinto, ukusebenza kunye neendlela zokufakela.
1. Umahluko kwizinto eziphathekayo
| Into | PP | I-PVC |
| Uxinano (g/cm3) | 0.9-0.91 | 1.38-1.45 |
| Indawo yokunyibilika (℃) | 160-170 | 75-90 |
| Ubushushu obuguquguqukayo bobushushu (℃) | 110 （0.45MPa） | 65 （0.45MPa） |
| I-coefficient yokwandisa umgca | 1.5×10⁻⁴/℃ | 6×10⁻⁵/℃ |
| Amandla okuxinana (MPa) | 30-40 | 50-60 |
2. Uthelekiso lweempawu zoomatshini
| Into | PP | I-PVC |
| Ukumelana neempembelelo | Icacile ukuba iyabhitya (<0 ℃) | Gcina ukuqina (-15 ℃) |
| Uxinzelelo lwexesha elide | Ukurhubuluza kwenzeka xa umthwalo uqhubeka (inkxaso kufuneka iqiniswe) | Ukumelana okuhle nokurhubuluza |
| Ubomi benkonzo | Iminyaka emi-3-5 | Ide ibe yi-20%-30% kune-PP |
| Isantya sokugcinwa | Iminyaka emi-3 | Iminyaka emi-5 |
3. Umahluko kunyango lwamanzi
| Into | PP | I-PVC |
| Ubuthambile bomphezulu | 0.8-1.2μm | 0.4-0.6μm |
| I-engile yokutyibilika kodaka | 55°-60° | 50°-55° |
| Ukunamathela kwi-biofilm | Ubuthathaka (ukungakhathali ngamanzi) | Oqinileyo (umphezulu we-polar) |
| Izinga lokuhamba koyilo (m/h) | 1.0-1.5 | 0.8-1.2 |
4. Umahluko ekufakweni
I-PP: Ukuwelda komoya oshushu (260-300 ℃) kufuneka kusetyenziswe
I-PVC: Ingadityaniswa nezinyibilikisi okanye idityaniswe kumaqondo obushushu aphantsi (180-220 ℃)
