Ulusi waukulu watatu wapamwamba kwambiri padziko lonse lapansi masiku ano ndi: aramid, carbon fiber, ultra-high molecular weight polyethylene fiber, ndi ultra-high molecular weight polyethylene fiber (UHMWPE) chifukwa cha mphamvu zake zapamwamba komanso modulus yeniyeni, imagwiritsidwa ntchito munkhondo, ndege, zinthu zophatikizika bwino (zipangizo zamasewera, zingwe, ndi zina zotero) zakhala zikugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Pakadali pano, ukadaulo wa ulusi wolemera kwambiri wa molekyulu ku China wapangidwanso mwachangu kwambiri. Pakadali pano, mumakampani olumikizirana, chinthu chachikulu chomwe chimagwiritsidwa ntchito kwambiri ndi ulusi wagalasi wolimbikitsidwa. M'zaka zingapo zapitazi, chakwezedwanso chifukwa cha magwiridwe antchito athunthu a ulusi wa aramid. Komabe, chifukwa cha zinthu zosiyanasiyana monga mtengo, msika wa ulusi wolimbikitsidwa wa aramid fiber (KEVLAR) ukuyamba kuchepa pang'onopang'ono, ndipo opanga ndi ogwiritsa ntchito ambiri amayang'ana kwambiri ulusi wa UHMWPE, chifukwa ulusi wolimbikitsidwa wa UHMWPE uli ndi mtengo wocheperako komanso magwiridwe antchito abwino. Komabe, chifukwa cha mawonekedwe osiyanasiyana a ulusi (kuphatikiza kukana kutentha, ndi zina zotero), zofunikira zapamwamba za ulusi wokonzedwa bwino komanso wonyowa zaperekedwa patsogolo. Kampani yathu yakula ndikuyika bwino ma resini a vinyl pa njira yopukutira ulusi wa Treated surface aramid, pachifukwa ichi, yabweretsa ulusi wa vinyl woyenera kupukutira ulusi wa molekyulu wolemera kwambiri, ndipo idagwiritsidwa ntchito m'magulu. Mtundu uwu wa maziko olimbikitsidwa ndi wotsika ndi 40% kuposa mtengo wa ulusi wa aramid, koma uli ndi mphamvu zambiri zopindika komanso zomangika.
