Ana amfani da shi akai-akai don rage ƙarin ƙwayoyin halitta don ƙananan ƙwayoyin halitta, wanda aka ƙara a yanayin narkewa lokacin da daidaiton manyan ƙwayoyin halitta ya karye, yana hana motsi na manyan ƙwayoyin halitta, don rage manufar ƙirƙirar ƙwayoyin halitta.

(2) Ƙara wasu gaurayen resin
Kamar ƙaramin adadin LDPE, resin HDPE da aka haɗa a cikin PP, zai iya lalata halayen kristal na PP sosai yayin sarrafawa, don ƙara resin PE a cikin PP, misali, tasirin abubuwan da ke ciki daban-daban na PE akan ƙimar raguwar PP an nuna su a cikin teburin da ke ƙasa. Bugu da ƙari, yana yiwuwa a ƙara resins marasa kristal kamar PS, ABS, PMMA da PC zuwa PP, wanda kuma zai iya taka rawa wajen rage lu'ulu'u.

Tasirin ƙara wasu resins akan raguwar ƙarfi ya yi ƙasa da tasirin zaruruwa masu cikewa da abubuwan cikawa marasa tsari, kuma gabaɗaya PP mai ƙarfafa zaruruwa ne kawai zai iya yin tasiri ga raguwar kusan kashi 50%.

4. Gyaran elastomer mai hadewa
Ana iya haɗa elastomers ciki har da POE, EPDM, SBS, da sauransu, duk nau'ikan elastomers akan ƙimar raguwar filastik yana kusa da tasirin.

Idan abun da ke cikin elastomer ya kasance ƙasa da kashi 5%, tasirin kowane nau'in elastomer akan raguwar PP abu ɗaya ne. Sai bayan abun da ke cikin elastomer ya wuce kashi 5%, matakin tasirin nau'ikan elastomer daban-daban zai bambanta, kuma tsarin tasirin akan ƙimar raguwa shine POE>EPDM>SBS, wanda yayi daidai da tasirin tauri na elastomers akan PP.

Amfani da abubuwan cikawa marasa tsari a cikin PP da aka haɗa da elastomers yana haifar da raguwar raguwar ƙanƙantawa.

5. Gyaran haɗa sinadarai da dasawa
Misali, yin amfani da resin PP wajen gyaran dashen zai iya rage yawan sinadarin resin, domin cimma manufar rage raguwar ... daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar daidaituwar
