Ulusi wagalasi, wotchedwa "ulusi wagalasi", ndi chinthu chatsopano cholimbitsa komanso cholowa m'malo mwa chitsulo. M'mimba mwake mwa monofilament ndi ma micrometer angapo mpaka ma micrometer opitilira makumi awiri, zomwe ndi zofanana ndi 1/20-1/5 ya ulusi wa tsitsi. Mtolo uliwonse wa ulusi wa ulusi umapangidwa ndi mizu yochokera kunja kapena ngakhale ulusi wambirimbiri.
Ulusi wagalasi uli ndi makhalidwe osayaka, osapsa ndi dzimbiri, osatentha, osatulutsa mawu, osagwira ntchito bwino, komanso osagwiritsa ntchito magetsi. Uli ndi ntchito zambiri ndipo umagwiritsidwa ntchito kwambiri pa zomangamanga, magalimoto, zombo, mapaipi a mankhwala, zoyendera njanji, mphamvu ya mphepo ndi zina.
Njira yopangira ulusi wagalasi ndikupera ndikusintha zinthu zopangira monga pyrophyllite kukhala zofanana, ndikuzisungunula mwachindunji mu uvuni wotentha kwambiri kuti apange madzi agalasi, kenako kujambula waya. Makina ojambula waya ndi chida chofunikira kwambiri popanga ulusi wagalasi, ndipo ndi makina omwe amakoka galasi losungunuka kukhala waya. Galasi losungunuka limatsikira pansi kudzera mu mbale yotayikira, ndipo limatambasulidwa mwachangu ndi makina ojambula waya, ndipo limakulungidwa mbali ina. Pambuyo pouma ndi kupotoza pambuyo pake, padzakhala chinthu cholimba cha ulusi wagalasi.
