Ibyiringiro byisoko rya firime Ntoya ni nziza, ituma ubwiyongere bwisoko ryisoko rya firime ntoya kubashoramari.

Polyester ikoreshwa muri rusange ni polyethylene terephthalate yo mu rwego rwamashanyarazi (polyester yo mu rwego rwamashanyarazi, PET), ifite ibimenyetso biranga dielectric ihoraho, imbaraga zidasanzwe kandi zifite amashanyarazi meza.

Filime ya capacitori yerekana firime ya plastike yo mu rwego rwamashanyarazi ikoreshwa nkibikoresho bya dielectric kubikoresho bya firime, bifite ibisabwa byihariye kubiranga amashanyarazi, nkimbaraga za dielectric nyinshi, gutakaza imbaraga nke, kwihanganira ubushyuhe bwinshi, kristu nyinshi nibindi. Ubushobozi buke bwa firime bukozwe muri firime yoroheje nkibikoresho fatizo bifite ibyiza byubushobozi buhamye, gutakaza bike, kurwanya voltage nziza, kurwanya insuline nyinshi, kuranga inshuro nyinshi no kwizerwa cyane, kandi bikoreshwa cyane mubikoresho bya elegitoroniki, ibikoresho byo murugo, itumanaho, amashanyarazi, amatara ya LED, ingufu nshya nizindi nzego.

Filime za capacitori ahanini ni polypropilene na polyester nkibikoresho fatizo, muri byo polypropilene muri rusange ni amashanyarazi yo mu bwoko bwa homopolymer polypropylene (high gauge homopolymer PP), ifite isuku nyinshi, irwanya ubushyuhe buhebuje, izirinda, ihindagurika ryimiti, irwanya ingaruka nibindi biranga. Polyester ikoreshwa muri rusange ni polyethylene terephthalate yo mu rwego rwamashanyarazi (polyester yo mu rwego rwamashanyarazi, PET), ifite ibimenyetso biranga dielectric ihoraho, imbaraga zidasanzwe kandi zifite amashanyarazi meza. Byongeye kandi, ibikoresho bya firime ya capacitor ikubiyemo kandi polystirene yo mu rwego rwamashanyarazi, polyakarubone, polyimide, polyethylene naphthalate, polifenile sulfide, nibindi, kandi umubare wibikoresho ni muto cyane.

Mu myaka yashize, hamwe n’iterambere ry’ubushinwa mu bumenyi n’ikoranabuhanga mu guhanga udushya, inganda nyinshi zagiye zica buhoro buhoro inzitizi zibangamira inganda, muri icyo gihe, filime ya capacitori y’Ubushinwa ikomeje kwiyongera, Leta kandi yashyizeho politiki zitandukanye zo gushishikariza no gushyigikira iterambere ry’inganda za firime za capacitor ndetse n’inganda zikoreshwa. Bikururwa n’icyerekezo cy’isoko kandi biterwa na politiki ishishikaje, ibigo bihari bikomeje kwagura umusaruro no gushyiraho umurongo wo gutunganya amafilime ku bushobozi, bikomeza kwiyongera mu kongera ubushobozi bw’amafirime y’Ubushinwa. Nk’uko bigaragazwa na "Raporo y'Ubushakashatsi ku Gukurikirana Isoko n'Iterambere ry'ejo hazaza Ibiteganijwe mu nganda z’inganda za Capacitor mu Bushinwa mu 2022-2026" byashyizwe ahagaragara n’ikigo cy’ubushakashatsi cy’inganda cya Xinsijia, kuva mu 2017 kugeza mu 2021, umusaruro w’inganda za firime za capacitori w’Ubushinwa wavuye kuri toni 167.000 ugera kuri toni 205.000.
