I-PP, ekwabizwa ngokuba yi-polypropylene, yipolymer eyenziwe nge-polypropylene kunye ne-alkene reaction, yinto emhlophe ye-waxy, ecacileyo kunye nenkangeleko elula.Ifomula yemichiza ngu (C3H6) x, ingxinano yi-0.89-0.91g/cm3, inokutsha, indawo yokunyibilika i-165℃, ukuthamba kwi-155℃, uluhlu lobushushu bokusebenzisa ngu-30～140℃.Ngaphantsi kwe-80 ℃ inokumelana nokuhlwa kweasidi, ialkali, ulwelo lwetyuwa kunye neentlobo ngeentlobo zezinyibilikisi eziphilayo, zinokubola phantsi kwefuthe lobushushu obuphezulu kunye ne-oxidation.I-pp bristles yenziwe nge-polypropylene, engaguquguqukiyo, engagugiyo kwaye ayinyanzelisi kakhulu kune-pbt, kwaye ngoko isetyenziswe kwiibrashi ezininzi zokucoca eziphantsi.

Nangona ii-pp bristles zitshiphu kakhulu, zinokusetyenziselwa ukukhupha iibhodi zesekethe, ngoba?Kuba i-pp ngokwayo itshajelwe ngombane, ukuba idityaniswe ne-toner eqhubayo ekumgangatho ophezulu, iya kuba sisandla esilungileyo sokuvula umsinga.
