I-Polypropylene ayinayo ityhefu, ayinavumba, kwaye ayinancasa icrystallinepolymer emhlophe ephezulu enendawo yokunyibilika eyi-164 ~ 170 ° C, ingxinano ye-0.90-0.91g/ cm%, kunye ne-molecularweight malunga ne-80,000 ukuya kwi-150,000. Yenye yezona zinto zikhaphukhaphu kuzo zonke iintlobo zeplastiki okwangoku. Izinzile ngakumbi emanzini, kwaye izinga lokufunxa kwamanzi emanzini iiyure ezingama-24 kuphela yi-0.01%6.
