ʻO Kevlar (Kevlar) ka inoa maoli o kahi huahana o DuPont, he ʻano mea polymer.ʻO kona inoa kemika ʻo "poly (terephthalamide)", i ʻike mau ʻia ʻo "aramid fiber".
ʻO Aramid ka inoa nui o ka polyamide aromatic.Hoʻohālikelike ʻia me nā mea polyamide maʻamau e like me ka nylon 6 a me ka nylon 66, he waiwai maikaʻi loa ka aramid e like me ka ikaika ultra-kiʻekiʻe, modulus kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe no ka mea ua hoʻololi ʻia ke kaulahao kalapona palupalu i loko o ke kaulahao molekala e ke apo apo benzene paʻa.Nui nā ʻano ʻano aramid, a hoʻohana nui ʻia ka aramid fiber 1313 a me ka aramid fiber 1414.Kevlar pili i ka aramid fiber 1414. ʻO ka inoa kemika o ka aramid fiber 1313 he polyphthalamide, he mea ahi maikaʻi loa.
I kēia manawa, ʻoi aku ka nui o ka noi makahiki o ka para-aramid fiber (aramid fiber 1414) ma Kina ma mua o 5,000 tons, e hilinaʻi nui ana i nā lawe mai, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai ma kahi o 200,000 yuan / ton.ʻO nā mea hana nui ʻo DuPont ma United States a me Teijin ma Iapana.
No ka m-aramid fiber (aramid fiber 1313), ʻo "Taimeida" i hana ʻia e Yantai Taihe New Materials Co., Ltd. ʻo ia ka lua o ka mākeke kiʻekiʻe loa ma ka honua a he ikaika ka mākeke mākeke.ʻO nā mea hoʻolako honua o ka m-aramid fiber ka nui o DuPont ma United States a me Teijin ma Iapana.Loaʻa iā Dupont ka māhele mākeke kiʻekiʻe loa a me nā kikoʻī huahana waiwai, a ʻo ia nō ke alakaʻi ʻoihana honua.
