Ulusi wopangidwa kuchokera ku ma polima opangidwa kuchokera kuzinthu zopangira monga mafuta. Mitundu yosiyanasiyana ya ulusi imapangidwa kuchokera kumitundu yosiyanasiyana yamankhwala. Ulusi uliwonse wopangidwa uli ndi mawonekedwe apadera komanso mawonekedwe omwe amauyenerera pakugwiritsa ntchito kwake. Zingwe zinayi zopangira -poliyesitala, polyamide (nayiloni), acrylic ndi polyolefin - amalamulira msika wa nsalu. Nsalu zopangira zimagwiritsidwa ntchito m'mafakitale ndi magawo osiyanasiyana, kuphatikiza, zovala, mipando, kusefera, magalimoto, ndege, zam'madzi, ndi zina.
Nsalu zopangapanga nthawi zambiri zimakhala ndi mapulasitiki, monga poliyesitala, omwe amayankha bwino pakukonza laser. Mtengo wa laser umasungunula nsaluzi mowongolera, zomwe zimapangitsa kuti m'mphepete mwake mukhale opanda burr komanso osindikizidwa.
