Lub hnab yas rau cov roj hmab hluav taws xob thiab roj hmab hluavtaws. Tshwj xeeb tsim rau cov khoom ntawm cov roj hmab log tsheb thiab khau roj hmab, cov khoom qub thiab lwm yam khoom siv. Cov khoom no yog non-polluting, soluble hauv benzene, ethanol, acetone thiab lwm cov organic solvents. Nws yog lub cev tsis muaj dej, tab sis nws yuav ua rau me ntsis xim nyob rau hauv cov xim kob dawb lossis kob xim. Nws yuav tsum tau siv nyob rau ntawm qhov kub siab tshaj 120 ° C, tshwj xeeb tshaj yog haum rau kev kub siab sib xyaws, thiab yuav tsum muab ntxiv thaum pib ntawm mastication. Tsis cuam tshuam rau cov laus cov khoom ntawm roj hmab cov khoom, tsis tsuag tshuaj yej. Tus nqi yog 0.05-0.5 ntawm cov roj hmab thiab 0.5-3 hauv styrene-butadiene roj hmab.
