Kukhazikika kwamafuta okhazikika. Chodziwika kwambiri cha aramid 1313 ndi kukana kwake kutentha, komwe kungagwiritsidwe ntchito kwa nthawi yayitali pa kutentha kwakukulu kwa 220 ℃ popanda kukalamba. Mphamvu zake zamagetsi ndi zamakina zimatha kusungidwa kwa zaka 10, ndipo kukhazikika kwake ndikwabwino kwambiri. Pafupifupi 250 ℃, kutsika kwake kwamafuta ndi 1% yokha; Kutentha kwakanthawi kochepa kwa 300 ℃ sikungayambitse kuchepa, kusungunula, kufewetsa, kapena kusungunuka; Zimangoyamba kuwola pa kutentha kopitilira 370 ℃; Mpweya wa carbon umangoyambira pafupifupi 400 ℃ - kukhazikika kwa kutentha koteroko sikochitika mu ulusi wosamva kutentha.

Kunyada lawi retadancy. Kuchuluka kwa mpweya wofunikira kuti zinthu ziwotche mumpweya zimatchedwa malire a oxygen index, ndipo akamakwera malire a oxygen index, m'pamenenso amayendetsa bwino lawi lake. Nthawi zambiri, mpweya wopezeka mumlengalenga ndi 21%, pomwe malire a oxygen index a aramid 1313 ndi akulu kuposa 29%, ndikupangitsa kuti ikhale fiber yoletsa moto. Chifukwa chake, sichidzayaka mumlengalenga kapena kuthandizira kuyaka, ndipo chimakhala ndi zozimitsa zokha. Chikhalidwe ichi chochokera ku mamolekyu ake ake chimapangitsa kuti aramid 1313 azitchinjiriza moto mpaka kalekale, chifukwa chake amadziwika kuti "fireproof fiber".

Kusungunula kwabwino kwamagetsi. Aramid 1313 ili ndi ma dielectric otsika kwambiri ndipo mphamvu yake ya dielectric imathandiza kuti ikhale yosasunthika bwino kwambiri pa kutentha kwambiri, kutentha pang'ono, komanso chinyezi chambiri. Pepala lotchinjiriza lomwe lakonzedwa nalo limatha kupirira ma voltages owonongeka mpaka 40KV/mm, ndikupangitsa kuti ikhale chida chodziwika bwino kwambiri padziko lonse lapansi.

Kukhazikika kwapadera kwamankhwala. Mapangidwe a mankhwala a aramid 1313 ndi okhazikika mwapadera, osagonjetsedwa ndi dzimbiri za ma inorganic acid ndi mankhwala ena, komanso osagonjetsedwa ndi hydrolysis ndi dzimbiri la nthunzi.

Wabwino makina katundu. Aramid 1313 ndi chinthu chosinthika cha polima chokhala ndi kuuma pang'ono komanso kutalika kwambiri, komwe kumapangitsa kuti ikhale yofanana ndi ulusi wamba. Itha kusinthidwa kukhala nsalu zosiyanasiyana kapena nsalu zosalukidwa pogwiritsa ntchito makina osokera wamba, ndipo sizimva kuvala komanso kung'ambika, zomwe zimagwiritsidwa ntchito mosiyanasiyana.

Super amphamvu radiation kukana. Aramid 1313 kugonjetsedwa ndi α, β, χ Kuchita kwa ma radiation kuchokera ku radiation ndi kuwala kwa ultraviolet ndikwabwino kwambiri. Kugwiritsa ntchito 50Kv χ Pambuyo pa maola 100 a radiation, mphamvu ya fiber idakhalabe pa 73% yake yoyambirira, pomwe poliyesitala kapena nayiloni anali atasanduka kale ufa.
