HP500N ili ndi chilolezo ndi Lyondell Basell's Spheripol teknoloji. Propylene yaiwisi imapangidwa kudzera mu njira ya PDH, ndipo sulfure yomwe ili mu propylene monomer ndiyotsika kwambiri. Mankhwalawa ali ndi makhalidwe amphamvu kwambiri, kukhazikika kwakukulu, ductility wabwino, kukonza kosavuta, kununkhira kochepa ndi zina zotero.
