Melting point: iav yog ib hom ntawm amorphous thiab tsis muaj qhov chaw melting tas. Nws feem ntau suav tias nws qhov taw qhia ntxaws yog 500 ~ 750 ℃
Boiling taw tes: txog 1000 ℃
Qhov ceev: 2.4 ~ 2.76 g / cm3
Thaum iav fiber ntau yog siv los ua cov khoom siv rau cov hnab yas coj los tiv thaiv cov plastics, qhov loj tshaj yog nws lub zog loj. Lub zog tensile yog 6.3 txog 6.9 g / d hauv lub xeev qhov qauv, thiab 5.4 txog 5.8 g / d hauv lub xeev ntub dej. Kev ua haujlwm zoo thaum tshav kub kub tsis kam, tsis muaj qhov cuam tshuam rau lub zog thaum ntsuas kub txog 300 ℃. Nws muaj zoo hluav taws xob rwb thaiv tsev thiab yog ib qib siab hluav taws xob rwb thaiv tsev ntaub. Nws kuj yog siv los ua cov khoom siv tiv thaiv tshav kub thiab cov khoom siv tiv thaiv hluav taws. Feem ntau tsuas yog corroded los ntawm concentrated alkali, hydrofluoric acid thiab concentrated phosphoric acid.
