1. Ezi n'ibu Njirimara Aramid bụ a mgbanwe polymer na elu na-agbasa ike karịa nkịtị polyester, owu, naịlọn, wdg, na ukwuu elongation, nro mmetụta na ezi spinnability, na ike Mere n'ime staple eri nke dịgasị iche iche denier na ogologo.N'ime ígwè ọrụ textile nkịtị, a na-eme eriri na filament ka ọ bụrụ yarn dị iche iche ma kpaa ya n'ime akwa na akwa na-abụghị nke a kpara akpa.Mgbe emechara, ọ nwere ike izute ihe ndị a chọrọ nke uwe nchebe na mpaghara dị iche iche.
2.Ezigbo ọkụ retardancy na okpomọkụ na-eguzogide.Meta-aramids nwere njedebe ikuku oxygen (LOI) karịa 28 ya mere anaghị aga n'ihu na-ere ọkụ mgbe ha na-ahapụ ọkụ.Ọrụ ọkụ na-egbochi ọkụ nke Newstar® meta-aramid dabere n'ụdị kemịkalụ nke ya, yabụ na ọ bụ eriri ọkụ na-adịgide adịgide nke na-agaghị ebelata ma ọ bụ tufuo ihe na-egbochi ire ọkụ n'ihi iji oge na oge ịsa ahụ.Newstar® meta-aramid nwere ezigbo nkwụsi ike nke okpomọkụ, enwere ike iji ya na-aga n'ihu na 205ºC, ma ka nwere ike ịnọgide na-enwe ike dị elu na okpomọkụ dị elu karịa 205°C.Newstar® meta-aramid nwere okpomọkụ ire ere dị elu, ọ gaghị agbaze ma ọ bụ gbazee.Na-agbaze n'okpuru ọnọdụ okpomọkụ dị elu.Carbonization na-amalite naanị na okpomọkụ karịa 370 Celsius.
3.Ngwongwo kemịkalụ siri ike meta-aramid nwere ezigbo nguzogide ọtụtụ kemịkalụ, nwere ike iguzogide ọtụtụ acid inorganic na-etinye uche dị elu, ma nwee nguzogide alkali dị mma n'ime ụlọ okpomọkụ.
4. Meta-aramid na-eguzogide radieshon nwere ezigbo nguzogide radieshon.Dịka ọmụmaatụ, n'okpuru ikpughe ogologo oge na ụzarị ultraviolet 1.2 × 10-2 w/in2 na ụzarị gamma 1.72 × 108rads, ike ha na-agbanwe agbanwe.
5. Meta-aramid na-adịgide adịgide na-enye esemokwu dị mma na nguzogide kemịkal.Mgbe 100 sachara, ike akwa akwa ejiri Newstar® meta-aramid mesoo ka nwere ike iru karịa 85% nke ike mbụ.
