PP, inozivikanwawo sepolypropylene, ipolymer yakagadzirwa nepolypropylene pamwe nealkene reaction, ichena waxy zvinhu, inopenya uye yakajeka muchitarisiko.Iyo kemikari formula ndeye (C3H6) x, density ndeye 0.89-0.91g/cm3, inogona kupisa, inonyunguduka 165 ℃, kupfava pa155 ℃, shandisa tembiricha yemhando -30～140℃.Pasi pe80 ℃ inogona kuramba kuodzwa kweasidhi, alkali, mvura yemunyu uye zvakasiyana siyana zvezvinonyungudutsa, zvinogona kuparara pasi pekupisa kwakanyanya uye oxidation.Iyo pp bristles yakagadzirwa nepolypropylene, iyo isingachinjiki, isingapfeki uye isinganyanyi kusemesa kupfuura pbt, uye saka inoshandiswa mumabhurashi mazhinji ekuchenesa.

Kunyangwe ma pp bristles akachipa zvakanyanya, anogona kushandiswa kuvhura mabhodhi edunhu, nei?Nekuti pp pachayo yakachajwa zvemagetsi, kana yakasanganiswa nemhando yepamusoro conductive toner, inove ruoko rwakanaka rwekusunungura yazvino.
