Cov roj hmab ua kua-hydroxyl xaus butadiene-styrene random copolymer (HTBS)
Cov Khoom thiab Kev Siv
HTBS yog cov kua copolymer ntawm butadiene thiab styrene nrog hydroxyl functional pawg nyob rau thaum kawg ntawm cov saw molecular, nws muaj kev tiv thaiv cua sov zoo heev, tiv thaiv kev sib txhuam, tiv thaiv kev laus, kev ua haujlwm zoo, tsim cua sov tsawg thiab qhov kub qis zoo.
Nws siv tau ua ke nrog roj hmab ntuj thiab roj hmab hluavtaws, thiab kuj siv tau ib leeg rau kev ua cov log tsheb polyurethane, cov nplaum rau hauv lauj kaub, cov nplaum, thiab lwm yam. Nws muaj kev ua tau zoo heev thiab tiv taus kev puas tsuaj thaum siv rau hauv roj hmab tread.
