Tụkwasị na nke ahụ, mgbanaka mkpuchi nkedo bụ mmanụ na-eguzogide mmanụ, hydrolysis na-eguzogide, na-eguzogide ọgwụ, ma nwee ike dị elu, nke kwesịrị ekwesị maka ngwá ọrụ mmanụ dị elu, ihe na-ebuli elu, ngwá ọrụ igwe na-emepụta ihe, nnukwu akụrụngwa hydraulic, wdg.
Polyurethane akara mgbanaka: polyurethane nwere ezigbo ihe eji arụ ọrụ, yana nguzogide ya na nguzogide nrụgide dị elu karịa rubbers ndị ọzọ. Nguzogide ịka nká, nguzogide ozone na nguzogide mmanụ dịkwa mma, mana ọ dị mfe iji hydrolyze na oke okpomọkụ. A na-ejikarị ya eme ihe maka njikọ mkpuchi na-eguzogide nrụgide dị elu, dị ka hydraulic cylinders. N'ozuzu, okpomọkụ nso bụ - 45 ~ 90 ℃.
Na mgbakwunye na imezu ihe ndị a chọrọ n'ozuzu maka ihe mkpuchi mkpuchi, mkpuchi mkpuchi polyurethane ga-aṅa ntị na ọnọdụ ndị a:
(1) Juputara na ngbanwe na ngbanwe;
(2) Ike igwe kwesịrị ekwesị, gụnyere ike mgbasawanye, elongation na nguzogide akwa mmiri.
(3) arụmọrụ kwụsiri ike, siri ike ịza na ọkara, yana obere mmetụta shrinkage thermal (Joule mmetụta).
(4) Ọ dị mfe ịhazi na ịkpụzi, ma nwee ike idowe oke nha.
(5) Ọ naghị emebi elu kọntaktị ma metọọ ọkara.
