Polyurethane yog dab tsi?

Polyurethane yog cov khoom siv polymeric nrog lub cev zoo thiab tshuaj lom neeg, nws cov yam ntxwv suav nrog

1. zoo txhua yam khoom: polyurethane muaj lub zog tensile siab, modulus ntawm elasticity thiab hardness, nrog rau zoo abrasion thiab qaug zog kuj.

2. Cov khoom siv tshuaj zoo: polyurethane muaj qhov ua haujlwm zoo rau cov roj, cov kuab tshuaj, cov kua qaub thiab alkalis thiab huab cua aging, thiab tsis yooj yim corroded.

3. Kev ua haujlwm zoo: polyurethane tuaj yeem ua tiav ntau txoj hauv kev, xws li kev txhaj tshuaj molding, extrusion, compression molding, txheej, thiab lwm yam.

4. Recyclability: Polyurethane tuaj yeem rov ua dua thiab rov siv dua, uas yuav pab txo cov khoom siv pov tseg thiab kev ua qias tuaj ib puag ncig.

Yog li ntawd, polyurethane yog siv dav hauv kev tsim kho, tsheb, hluav taws xob, khoom siv ua kis las, khau, rooj tog thiab lwm yam.
