Mgbe 100 sachara, ike ndọka nke akwa m-aramid ka nwere ike iru karịa 85% nke ike mbụ ha. Nguzogide okpomọkụ nke para-aramids dị elu karịa nke inter-aramids, na-eji ọnọdụ okpomọkụ na-aga n'ihu -196°C ruo 204°C na enweghị ire ere ma ọ bụ agbaze na 560°C. Ihe kachasị dị ịrịba ama nke para-aramid bụ ike dị elu na modul dị elu, ike ya karịrị 25g / dan, nke bụ oge 5 ~ 6 nke ígwè dị elu, oge 3 nke eriri iko na oge 2 nke akwa nylon ụlọ ọrụ mmepụta ihe; modul ya bụ 2 ~ 3 ugboro nke elu mma ígwè ma ọ bụ iko eriri na 10 ugboro nke elu ike nylon ụlọ ọrụ yarn. Ọdịdị elu pụrụ iche nke aramid pulp, nke a na-enweta site na fibrillation elu nke eriri aramid, na-eme ka njide nke ogige ahụ dịkwuo mma ma ya mere ọ dị mma dị ka eriri na-eme ka ọ dị ike maka esemokwu na ngwaahịa mkpuchi. Aramid Pulp Hexagonal Special Fiber I Aramid 1414 Pulp, ìhè odo flocculent, plush, na ụbara plumes, ike dị elu, ezigbo akụkụ kwụsie ike, na-abụghị kenkuwa, elu okpomọkụ na-eguzogide, corrosion eguzogide, siri ike, ala shrinkage, ezi abrasion nguzogide, nnukwu elu ebe, ezi bonding na ihe ndị ọzọ, a ume ike ihe onwunwe na nkezi nke 8% nke elu mmiri, elu nke elu 8% na elu. mpaghara 8m2/g. A na-eji ya dị ka ihe na-eme ka gasket na-eme ka ọ dị mma na-arụ ọrụ nke ọma, ọ dịghịkwa emerụ ahụ ike mmadụ na gburugburu ebe obibi, a pụkwara iji ya mee ihe maka mkpuchi na mmiri, mmanụ, ike dị iche iche na ọkara acid na alkali media. E gosiputara na ike nke ngwaahịa ahụ bụ 50-60% nke ngwaahịa asbestos fiber na-emesi ike mgbe agbakwunyere ihe na-erughị 10% nke slurry. A na-eji ya na-eme ka esemokwu na ihe mkpuchi na ngwaahịa ndị ọzọ arụpụtara, enwere ike iji ya dị ka ihe ọzọ maka asbestos maka ihe mkpuchi esemokwu, akwụkwọ mkpuchi mkpuchi okpomọkụ na-arụ ọrụ dị elu na ihe mgbagwoju anya.
