PU yog cov khoom siv organic polymer uas tau siv dav hauv ntau lub teb chaws kev lag luam vim nws qhov kev ua tau zoo heev.
Nws tau muab faib ua cam khwb cia polyurethane elastomer (hu ua CPU), thermoplastic polyurethane elastomer (hu ua TPU), thiab sib xyaw polyurethane elastomer (hu ua MPU).
CPU: Cam khwb cia polyurethane elastomer (CPU) yog ib yam tshiab ntawm cov khoom siv hluavtaws polymer ntawm roj hmab thiab yas. Hauv kev siv tswv yim, nws feem ntau yog siv los hloov cov khoom siv roj hmab. Vim tias CPU muaj qhov ua tau zoo tshaj plaws Abrasion tsis kam (qhov zoo tshaj plaws ntawm elastomers), cam khwb cia polyurethane elastomer (CPU luv luv) kuj hu ua thermosetting elastomer. Nws ua kua nyob rau hauv chav tsev kub thiab ua khoom tom qab ua tiav. Yog li ntawd, CPU feem ntau siv rau kev ua haujlwm casting, xws li casters, Mining, roj refining, textile, tshuab luam ntawv rollers, cov khoom tiav yog muaj zog hnav tsis kam.
TPU: Thermoplastic polyurethane elastomer (TPU luv luv) kuj yog ib yam tshiab ntawm cov khoom siv hluavtaws polymer ntawm roj hmab thiab yas. Hauv kev siv tswv yim, nws feem ntau yog siv los hloov cov khoom siv roj hmab thiab tseem muaj feem xyuam nrog CPU. Kev hnav zoo heev (qhov zoo tshaj plaws ntawm elastomers), nws dhau los ua khoom ntawm chav tsev kub. Nws ua kua los ntawm cua sov los yog tov. Tom qab ua tiav thiab shaping, nws dhau los ua cov khoom siv polyurethane dua.
TPU yog cov khoom siv dav siv thiab tsim ntau hom polyurethane elastomer, xws li cov khoom siv kis las: skate wheels, skates, buckles, accessories, thiab snow boots. Cov khoom lag luam: cov ntsaws ruaj ruaj, nws pib qhov chaw (cov kav dej pov thawj pov thawj, cov yeeb nkab fittings, kev poob siab absorbers, muaj log, conveyor txoj siv sia. Cov khoom siv yeeb nkab: cov kav dej cua siab, cov kav dej tua hluav taws, cov kav dej kho mob ... cov hlau thiab cables, strips, watch straps, films. Cov ntaub ntawv khau: khau, khau khiab, cua cushions, accessories, tawv, spikes, ntawv lo, thiab lwm yam.
