Khoom Taw qhia
PU Rod
PU pas nrig yog cov khoom siv hluav taws xob tshiab ntawm cov roj hmab thiab cov yas, uas muaj kev siv siab ntawm cov yas thiab cov roj hmab siab elasticity, zoo heev hnav tsis kam thiab tenacity (lub npe hu ua "coj-tiv taus roj hmab"), siab siv thiab elasticity, muaj peev xwm nqa tau ntau dua. Lwm cov elastomers nyob rau hauv tib lub hardness, muaj kev cuam tshuam tsis kam, zoo qaug zog thiab kev co kuj, nrog rau zoo heev tearing kuj, aging kuj, roj kuj thiab tshuaj tsis kam.
Cov khoom sivn
Lawv yog cov ntaub ntawv muab ntau yam khoom tshwj xeeb uas ua rau cov khoom tsim los ua kom tau raws li ntau yam kev thov. Cov nqi zoo tshaj thiab kev ua tau zoo tau ua rau ntau zaus ntawm kev hloov cov hlau, roj hmab, ntoo thiab yas nrog casting Polyurethane elastomer.
