Polybutadiene Rubber (PBR) yog hydrophobic. Lub ntsiab saw hlau ntawm polybutadiene ua rau nws hydrophobic, uas yog manifested nyob rau hauv lub fact tias cov tsis-polar ib feem nyob rau hauv nws cov qauv molecular ua rau polybutadiene tsis yooj yim wetted los ntawm dej. Tsis tas li ntawd, hydroxy-terminated polybutadiene (HTPB) kuj muaj hydrophobicity zoo heev, thiab nws cov khoom kho tau zoo hydrolysis tsis kam thiab qis-kub yooj.
Lub hydrophobicity ntawm polybutadiene ua rau nws ua tau zoo nyob rau hauv ntau yam kev siv. Piv txwv li, nws yog feem ntau siv los tsim cov khoom siv roj hmab xws li cov log tsheb, hoses, tapes, seals, soles thiab cables, tag nrho cov uas xav tau cov khoom kom muaj dej tsis zoo.
