Munguva ichangopfuura, mutengi akabvunza mutengo we polypropylene tambo, mutengi mugadziri wekuredza mambure kunze kwenyika, anowanzo shandiswa polyethylene tambo, asi polyethylene tambo yakanyanya kutetepa, nyore kusunungura mushure mekupfumbura, uye mukana wetambo waya tambo ndeyekuti iyo monofilament yetambo yakaoma, knotting haisi nyore kutsvedza.Asi polypropylene inorema kupfuura polyethylene.Nechepfungwa, iyo molecular formula yepropylene ndeye CH3CH2CH3, uye iyo molecular formula ye ethylene ndeye CH3CH3.Polypropylene ine atomu imwe kabhoni pane polyethylene, saka huremu hwetambo yepolypropylene hunorema kupfuura polyethylene.

Chimiro che polyethylene ndeichi:

—(CH2-CH2-CH2-CH2)n—-

Chimiro che polypropylene ndeichi:

—(CH2-CH(CH3)-CH2-CH(CH3)-CH2-CH(CH3))n—-

Inogona kuonekwa kubva kune chimiro kuti polypropylene ine ketani yebazi kupfuura polyethylene.Mushure mekugadzira tambo, nekuda kwebasa reketani yebazi, tambo yepolypropylene ine simba rakasimba kupfuura polyethylene, uye hazvisi nyore kutsvedza.Density ye polypropylene i 0.91 uye density ye polyethylene i 0.93, saka polyethylene inofanira kurema.

Tambo yepolyethylene inonyanya kuchinjika, yakapfava uye yakapfava kupfuura polypropylene.
