Cov thermal stability. Qhov tseem ceeb tshaj plaws ntawm aramid 1313 yog nws qhov kub thiab txias, uas tuaj yeem siv tau ntev ntawm qhov kub ntawm 220 ℃ tsis muaj kev laus. Nws cov khoom siv hluav taws xob thiab cov khoom siv kho tshuab tuaj yeem khaws cia txog li 10 xyoo, thiab nws qhov kev ruaj ntseg zoo heev. Nyob ib ncig ntawm 250 ℃, nws thermal shrinkage tus nqi tsuas yog 1%; Lub sij hawm luv luv rau qhov kub siab ntawm 300 ℃ yuav tsis ua rau shrinkage, embrittlement, softening, los yog melting; Nws tsuas yog pib decompose ntawm qhov kub siab tshaj 370 ℃; Carbonization tsuas yog pib ntawm ib ncig ntawm 400 ℃ - xws li thermal stability yog tsis tshua muaj nyob rau hauv cov organic tshav kub-resistant fibers.

Txaus siab nplaim taws retardancy. Qhov feem pua ​​​​ntawm cov pa oxygen xav tau rau cov khoom siv los hlawv hauv huab cua yog hu ua qhov txwv oxygen index, thiab qhov siab dua qhov txwv oxygen index, qhov zoo dua nws cov nplaim hluav taws. Feem ntau, cov ntsiab lus ntawm cov pa oxygen hauv huab cua yog 21%, thaum qhov txwv oxygen index ntawm aramid 1313 yog ntau dua 29%, ua rau nws cov nplaim hluav taws kub. Yog li ntawd, nws yuav tsis hlawv nyob rau hauv cov huab cua los yog pab nyob rau hauv combustion, thiab nws tus kheej extinguishing zog. Cov yam ntxwv tseem ceeb no tau muab los ntawm nws tus kheej cov qauv molecular ua rau aramid 1313 mus tas li nplaim taws retardant, li no nws yog hu ua "fireproof fiber".

Hluav taws xob rwb thaiv tsev zoo heev. Aramid 1313 muaj qhov tsis tshua muaj dielectric tsis tu ncua thiab nws lub zog muaj zog dielectric ua rau nws tswj tau cov hluav taws xob zoo hauv qhov kub thiab txias, tsis tshua muaj kub, thiab cov av noo siab. Cov ntawv rwb thaiv tsev npaj nrog nws tuaj yeem tiv taus qhov hluav taws xob tawg mus txog 40KV / mm, ua rau nws yog lub ntiaj teb lees paub cov khoom siv rwb thaiv tsev zoo tshaj plaws.

Zoo tshuaj stability. Cov qauv tshuaj ntawm aramid 1313 yog qhov ruaj khov, tiv taus corrosion ntawm feem ntau cov concentrated inorganic acids thiab lwm yam tshuaj, thiab resistant rau hydrolysis thiab chav corrosion.

Zoo heev mechanical zog. Aramid 1313 yog cov khoom siv polymer hloov tau nrog qhov tsis tshua muaj zog thiab siab elongation, uas muab nws tib yam spinnability zoo li cov fibers zoo tib yam. Nws tuaj yeem ua tiav rau hauv ntau yam ntaub lossis cov ntaub tsis-woven siv cov tshuab spinning, thiab hnav-resistant thiab tsim kua muag, nrog rau ntau yam kev siv.

Super muaj zog hluav taws xob tiv thaiv. Aramid 1313 resistant α、β、χ Kev ua haujlwm ntawm hluav taws xob los ntawm hluav taws xob thiab ultraviolet lub teeb yog zoo heev. Siv 50Kv χ Tom qab 100 teev ntawm hluav taws xob, lub zog fiber ntau tseem nyob ntawm nws qhov qub 73%, thaum polyester lossis nylon twb dhau los ua hmoov.
