3.Main Functions and Applications (Nws yog dab tsi siv?)
- Polyurethane (cov ntaub ntawv tseem ceeb):Mos- ntu polyol rau polyurethane elastomers, TPU, coatings, adhesives, hluavtaws tawv thiab khau, imparting zoo yooj yooj yim, tsis tshua muaj - kub softness, hydrolysis tsis kam (zoo tshaj rau polyester polyols) thiab resilience.
- Adhesives thiab sealants:Polyol tivthaiv ntawm kub- yaj thiab ya raws- kho cov nplaum.
- Txheej:High -kev ua tau zoo PU txheej rau tsheb, ntoo thiab yas.
- Elastomers:Castable PU elastomers (kev lag luam rollers, ntsaws ruaj ruaj, gaskets).
- Biodegradable cov ntaub ntawv:Biodegradable polyester polyol rau eco- cov ntaub ntawv tus phooj ywg.
- Cov qib muaj:Ntau qib molecular- hnyav qib (Mn 530–3000) sib haum rau qhov sib txawv hydroxyl qhov tseem ceeb thiab mos- ntu ntev, ua kom hloov tau yooj yim ntawm PU kev ua tau zoo.
4.A Benchmark-Level Industrial Masterpiece - A Meticulously Crafted "PU-Grade" Cornerstone Macrodiol!
Precisely tswj hydroxyl tus nqi thiab molecular hnyav. Ultra- qis acidity thiab noo noo.
Nqaim molecular hnyav faib. Zoo heev yooj thiab hydrolysis kuj.
"Qhov koj pom yog qhov koj tau txais" - txhua lub nkoj nrog daim ntawv pov thawj tiav ntawm kev tshuaj xyuas.
