Cov kua roj hmab-hydroxyl terminated butadiene-styrene random copolymer (HTBS)
Khoom thiab Kev Siv
HTBS yog cov kua copolymer ntawm butadiene thiab styrene nrog hydroxyl ua haujlwm pab pawg ntawm qhov kawg ntawm cov saw hlau molecular, nws muaj cov cua sov zoo heev, ua kom tsis muaj zog, tiv thaiv kev laus, kev ua haujlwm zoo, tsis tshua muaj cua sov thiab zoo kub hloov tau yooj yim.
Nws tuaj yeem siv ua ke nrog cov roj hmab ntuj thiab cov roj hmab hluavtaws, thiab tseem tuaj yeem siv ib leeg rau casting polyurethane log tsheb, potting adhesive, nplaum, thiab lwm yam.
