Ọrụ PPO na-ekpebi mpaghara ngwa yana oke ojiji ya:
1) MPPO nwere obere njupụta, dị mfe hazie, thermal deformation okpomọkụ na 90 ~ 175 ℃, dị iche iche nkọwa nke commodities, ezi akụkụ kwụsie ike, adabara imewe nke ụlọ ọrụ ngwá, ezinụlọ ngwa, kọmputa na ndị ọzọ igbe, chassis na nkenke akụkụ.
2) The dielectric mgbe niile na dielectric ọnwụ Angle tangent nke MPPO bụ ndị kasị ala n'etiti ise n'ozuzu engineering plastics, ya bụ, ihe mkpuchi kasị mma na ezigbo okpomọkụ na-eguzogide, kwesịrị ekwesị maka eletriki ụlọ ọrụ.
Kwesịrị ekwesị maka imepụta akụkụ mkpuchi ọkụ eletrik eji na ọnọdụ mmiri na ibu, dị ka mkpuchi mkpuchi, isi tube, ogwe njikwa, ọta ihe ntụgharị, igbe agba agba, mkpuchi mkpuchi, wdg.
3) MPPO mmiri na-eguzogide mmiri na ikpo ọkụ ọkụ, mmiri dị mma, kwesịrị ekwesị maka ịmepụta mita mmiri, nfuli.
Ọkpụkpọ yarn a na-eji na ụlọ ọrụ akwa kwesịrị ịdị na-eguzogide mkpụrụ dijitalụ. tube yarn nke MPPO mere nwere ogologo ndụ ọrụ.
4) The dielectric na-adịgide adịgide na dielectric ọnwụ Angle tangent nke MPPO na engineering plastics adịghị emetụta okpomọkụ na ugboro ugboro, na okpomọkụ na-eguzogide na akụkụ kwụsie ike dị mma, kwesịrị ekwesị maka electronic ụlọ ọrụ.
