Muaj ntau qhov chaw uas cov yeeb yaj kiab polyimide tuaj yeem siv tau. Yog li ntawd, ntau thiab ntau cov neeg muas zaub tau them sai sai rau cov khoom no. Ntau tus neeg siv khoom thiab cov phooj ywg xav paub seb cov yeeb yaj kiab polyimide ua li cas. Hauv qab no, cov kws tshaj lij kev lag luam tau ua cov lus qhia ntxaws ntxaws, cia peb ua tib zoo saib ua ke.

Txoj kev npaj zaj duab xis yog raws li nram no: nrum polyamic acid tov rau hauv zaj duab xis, ncab thiab imidize nws ntawm qhov kub thiab txias. Cov zaj duab xis yog daj thiab pob tshab, nrog ib tug txheeb ze ntom ntawm 1.39 ~ 1.45. Nws muaj qhov kub thiab txias tsis kam, hluav taws xob tiv thaiv, tshuaj tiv thaiv corrosion thiab hluav taws xob rwb thaiv tsev, thiab tuaj yeem siv tau ntev hauv huab cua ntawm 250 ~ 280 ℃. Cov iav hloov pauv kub siab tshaj 280 ° C (Upilex R), 385 ° C (Kapton) thiab 500 ° C (Upilex S). Lub zog tensile yog 200 MPa ntawm 20 ° C thiab tshaj 100 MPa ntawm 200 ° C. Nws yog tshwj xeeb tshaj yog haum rau siv raws li substrates thiab insulating cov ntaub ntawv rau saj zawg zog luam Circuit Court boards ntawm ntau yam high-temperature resistant motors thiab cov khoom siv hluav taws xob.
