Tshwj xeeb Polyether-Low Molecular Nyhav PET Polyether
Khoom thiab Kev Siv
Nws yog kua ntawm chav tsev kub, uas yog yooj yim rau siv thiab txheej txheem. Cov iav hloov pauv kub ntawm -80 ℃, nrog kev ua tau zoo ntawm qhov kub thiab txias, cov khoom siv kho tshuab ntawm nws cov khoom siv elastomer thiab PTMG nyob ze rau PTMG, tuaj yeem hloov PTMG hauv qhov kub thiab txias ib puag ncig.
Nrog zoo molecular yooj, nws muaj peev xwm hloov PTMG nyob rau hauv saj zawg zog dag tawv thiab luam ntawv number case; Nws tuaj yeem siv rau hauv cov nplaum uas tsis tshua muaj kub-resistant, coatings, polyurethane elastomers thiab lwm yam.
