Kev faib tawm ib txwm muaj ntawm polyurethane elastomers yog raws li cov txheej txheem ua, uas tau muab faib ua cam khwb cia polyurethane elastomers, sib xyaw polyurethane elastomers thiab thermoplastic polyurethane elastomers.
Vim muaj cov ntaub ntawv sib txawv, kev sib xyaw thiab kev ua haujlwm, thiab cov hom phiaj siv, cov tshuaj tiv thaiv kev txhaj tshuaj polyurethane elastomers (RIMPU) thiab cov tshuaj-dispersed polyurethane elastomers tau tshwm sim. Raws li daim ntawv tsim, nws tau muab faib ua cov khoom siv thiab cov kua system.
Nws kuj tau muab faib raws li cov tshuaj muaj pes tsawg leeg ntawm raw cov ntaub ntawv. Feem ntau, muaj polyester lossis polyether, yog li muaj polyether polyurethane elastomer thiab polyester polyurethane elastomer.
