Polypropylene ndi wamba pulasitiki chuma ndi wabwino kukana kutentha, kukana dzimbiri ndi mawotchi katundu, choncho chimagwiritsidwa ntchito makampani ndi moyo watsiku ndi tsiku. Komabe, chifukwa cha mphamvu zake zoyaka moto, zoletsa moto zimafunika kuwonjezeredwa kuti ziwongolere mphamvu zake zoletsa malawi. Zotsatirazi zikuwonetsa zoletsa zamoto zomwe zingagwiritsidwe ntchito pa polypropylene.
Aluminiyamu triphosphate: Aluminiyamu triphosphate ndi chinthu chomwe chimagwiritsidwa ntchito mofala kwambiri choletsa moto cha halogen chomwe chimatha kuwongolera bwino mphamvu ya polypropylene yoletsa malawi. Ikhoza kumasula phosphorous oxides pa kutentha kwambiri kuti apange wosanjikiza zoteteza kuteteza kufalikira kwa mpweya ndi kutentha, potero kukwaniritsa lawi retardant zotsatira.
Aluminiyamu hydroxide: Aluminiyamu hydroxide ndi yopanda poizoni, yopanda fungo, komanso yosawononga lawi lamoto yomwe imatha kuwongolera bwino mphamvu yamoto ya polypropylene. Imawola pa kutentha kwakukulu kuti itulutse nthunzi wa madzi, kuyamwa kutentha, ndi kuchepetsa kutentha ndi kutentha kwa polypropylene.
Aluminiyamu silicate: Aluminiyamu silicate ndi halogen-free lawi retardant amene angathe kusintha bwino flame retardant katundu wa polypropylene. Ikhoza kuwola pa kutentha kwakukulu kuti itulutse mpweya wa madzi ndi silicon dioxide kuti ipange chinsalu choteteza kuti chiteteze kufalikira kwa mpweya ndi kutentha, potero kukwaniritsa zotsatira zamoto.
Ammonium polyphosphate ndi phosphorous-nitrogen retardant lawi ndi katundu wabwino retardant malawi ndi matenthedwe bata, ndipo chimagwiritsidwa ntchito polypropylene zipangizo. Ammonium polyphosphate akhoza kuwola pa kutentha kwambiri kumasula phosphorous oxides ndi ammonia, kupanga mpweya wosanjikiza kuteteza kufalikira kwa mpweya ndi kutentha, potero bwino kuwongolera lawi retardant zimatha polypropylene. Kuphatikiza apo, ammonium polyphosphate ilinso ndi mawonekedwe a kawopsedwe otsika, kutsika pang'ono komanso kusamala zachilengedwe, zomwe zimapangitsa kuti ikhale yabwino yoletsa moto wa polypropylene.
M'munda wamafakitale, ammonium polyphosphate imagwiritsidwa ntchito kwambiri pazinthu zoyaka moto za polypropylene, monga zida zamagetsi, zomangira, zida zamagalimoto ndi magawo ena. Makhalidwe ake abwino kwambiri oletsa moto komanso mawonekedwe oteteza chilengedwe azindikirika ndikugwiritsidwa ntchito. Panthawi imodzimodziyo, pamene zofunikira za anthu pachitetezo cha chilengedwe ndi ntchito zachitetezo zikuwonjezeka, ammonium polyphosphate, monga chowotcha chamoto chopanda halogen, chidzagwira ntchito yowonjezereka mu zipangizo za polypropylene.
Kawirikawiri, polypropylene, monga pulasitiki wamba, imayenera kuwonjezera zotetezera moto kuti ziwongolere mphamvu zake zoyaka moto. Aluminiyamu triphosphate, aluminium hydroxide, aluminium silicate, ndi zina zambiri ndi zoletsa moto zomwe zitha kupakidwa polypropylene, ndi ammonium polyphosphate, monga phosphorous-nitrogen retardant lawi, ali ndi chiyembekezo chogwira ntchito mu polypropylene.
