Synthetic roj hmab polymers yog hluavtaws, heev elastic polymers, tseem hu ua hluavtaws elastomers, thiab yog ib qho ntawm peb cov khoom siv hluavtaws loj. Nws cov khoom siv tsuas yog qis dua li cov khoom siv hluavtaws (los yog cov yas) thiab cov hluavtaws fibers. Cov roj hmab hluavtaws yog chemically synthesized thiab yog qhov txawv ntawm cov roj hmab ntuj tsim los ntawm cov ntoo roj hmab.
Cov roj hmab hluavtaws feem ntau yog muab los ntawm cov polymers ntxiv ntawm polyene monomers thiab, tshwj tsis yog cov roj hmab hluavtaws tau nthuav tawm raws li cov roj hmab polysulfide, laminates uas muaj xws li txheej yuav raug cais nrog cov polymers ntxiv.
PBR, luv luv rau Polybutadiene Roj Hmab, yog ntau yam hluavtaws roj hmab ua los ntawm polymerizing 1, 3-butadiene. Raws li nws cov qauv molecular, nws tuaj yeem muab faib ua cov roj hmab trans-polybutadiene thiab cis-polybutadiene roj hmab. Cis-polybutadiene roj hmab yog ntxiv categorized rau hauv high-cis, nruab nrab-cis, thiab low-cis polybutadiene nyob ntawm seb cov ntsiab lus cis.
Polybutadiene roj hmabmuaj ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv lub log tsheb kev lag luam, qhov twg nws yog siv nyob rau hauv lub sidewalls thiab treads ntawm log tsheb vim nws zoo heev roj kuj, abrasion tsis kam, thiab aging kuj, ua rau nws zoo tagnrho rau radial log tsheb sidewalls. Tshaj li cov log tsheb, PBR kuj tau siv dav hauv kev tsim cov roj hmab hoses, cov roj hmab khau, cov hlua conveyor, thiab ntau yam khoom siv roj hmab.
