He maikaʻi nā manaʻo o ka mākeke o nā kiʻiʻoniʻoni lahilahi, e alakaʻi ana i ka ulu ʻana o ka mākeke koi no nā kiʻiʻoniʻoni lahilahi no nā capacitors.

ʻO ka polyester i hoʻohana ʻia ʻo ia ka polyethylene terephthalate uila (electric-grade polyester, PET), nona nā hiʻohiʻona o ke kiʻekiʻe dielectric mau, kiʻekiʻe tensile ikaika a me nā waiwai uila maikaʻi.

ʻO ke kiʻiʻoniʻoni Capacitor e pili ana i ke kiʻiʻoniʻoni uila uila i hoʻohana ʻia ma ke ʻano he mea dielectric no nā capacitors kiʻiʻoniʻoni, nona nā koi kūikawā no nā hiʻohiʻona uila, e like me ka ikaika dielectric kiʻekiʻe, haʻahaʻa haʻahaʻa, kiʻekiʻe wela ke kūpaʻa, kiʻekiʻe crystallinity a pēlā aku. ʻO nā capacitors kiʻiʻoniʻoni lahilahi i hana ʻia i ka kiʻiʻoniʻoni ʻoniʻoni e like me nā mea maka i nā mea maikaʻi o ka capacitance paʻa, haʻahaʻa haʻahaʻa, maikaʻi loa ka pale ʻana i ka uila, kiʻekiʻe insulation kūpaʻa, nā hiʻohiʻona alapine maikaʻi a me ka hilinaʻi kiʻekiʻe, a hoʻohana nui ʻia i ka uila, nā mea hana home, nā kamaʻilio, nā uila uila, nā kukui LED, ka ikehu hou a me nā māla ʻē aʻe.

ʻO nā kiʻiʻoniʻoni Capacitor ka hapa nui o ka polypropylene a me ka polyester ma ke ʻano he kumu, ʻo ia ka polypropylene ma ke ʻano he uila homopolymer polypropylene (high gauge homopolymer PP), me ka hoʻomaʻemaʻe kiʻekiʻe, ke kūpaʻa wela maikaʻi loa, ka insulation, ke kūpaʻa kemika, ke kūpaʻa hopena a me nā ʻano ʻē aʻe. ʻO ka polyester i hoʻohana ʻia ʻo ia ka polyethylene terephthalate uila (electric-grade polyester, PET), nona nā hiʻohiʻona o ke kiʻekiʻe dielectric mau, kiʻekiʻe tensile ikaika a me nā waiwai uila maikaʻi. Eia kekahi, ʻo nā mea o ke kiʻi capacitor e komo pū me ka polystyrene grade electrician, polycarbonate, polyimide, polyethylene naphthalate, polyphenylene sulfide, etc., a ʻo ka nui o kēia mau mea he liʻiliʻi loa.

I kēia mau makahiki i hala iho nei, me ka hoʻomaikaʻi ʻana i ka ikaika o ka ʻepekema a me ka ʻenehana hou o Kina, ua ʻoi aku ka nui o nā ʻoihana i nā keʻakeʻa i ka ʻoihana, i ka manawa like, ke hoʻomau nei ka ulu ʻana o ke koi kiʻi capacitor o Kina, ua hoʻokumu pū ka mokuʻāina i kahi ʻano o nā kulekele e paipai a kākoʻo i ka hoʻomohala ʻana i ka ʻoihana kiʻi capacitor a me kāna mau noi noi. Hoʻopili ʻia e nā mākaʻikaʻi mākeke a alakaʻi ʻia e nā kulekele hoʻoikaika, hoʻomau nā ʻoihana i kēia manawa e hoʻonui i ka pae hana a waiho i nā laina hana kiʻiʻoniʻoni no nā capacitors, e hoʻoikaika hou i ka piʻi ʻana o ka mana hana kiʻiʻoniʻoni capacitor o Kina. Wahi a ka "Research Report on the Market Monitoring and Future development Prospects of China's Capacitor Film Industry in 2022-2026" i hoʻokuʻu ʻia e Xinsijia Industry Research Center, mai 2017 a 2021, ua hoʻonui ka mana hana o ka ʻoihana kiʻi kiʻi capacitor Kina mai 167,000 tons a 205,000.
