PP, izwi kandi nka polypropilene, ni polymer ikozwe muri polypropilene wongeyeho alkene reaction, ni ibikoresho byashashara byera, bibonerana kandi byoroshye mumiterere.Imiti yimiti ni (C3H6) x, ubucucike ni 0.89-0.91g / cm3, gutwikwa, gushonga 165 ℃, koroshya kuri 155 ℃, gukoresha ubushyuhe ni -30 ～ 140 ℃.Munsi ya 80 ℃ irashobora kurwanya ruswa ya aside, alkali, amazi yumunyu hamwe nudukoko twinshi twa organic organic, irashobora kubora bitewe nubushyuhe bwinshi na okiside.Urupapuro rwa pp rukozwe muri polypropilene, idahinduka cyane, idashobora kwihanganira kwambara kandi ntigishobora kwangwa kurusha pbt, bityo ikoreshwa mumashanyarazi menshi yo hasi.

Nubwo pp ya pp ihendutse cyane, irashobora gukoreshwa muguhagarika imbaho ​​zumuzunguruko, kubera iki?Kuberako pp ubwayo yishyuzwa amashanyarazi, niba ihujwe na toner yujuje ubuziranenge, bizaba ikiganza cyiza cyo guhagarika ikigezweho.
