Cov thev naus laus zis loj tau ua tiav hauv cov txuj ci tseem ceeb thev naus laus zis ntawm lub hnub qub branched butyl / brominated butyl rubber synthesis thiab ob chav B-qib cov log tsheb npaj thev naus laus zis. Kev pab cuam lub neej ntawm butyl vulcanization capsules tau nce ntau dua li 17% ntawm lub hauv paus, thiab cov ntws tsis kam thiab ntub dej tsis kam ua haujlwm ntawm cov log tsheb hauv tsev tau nce mus rau ob kauj ruam mus rau B-qib txuj, uas yuav ua cov khoom siv roj hmab hluavtaws. hauv log. Kev nce ntxiv ntawm ntau dua 15% hauv kev npaj log yuav txhawb nqa Tuam Tshoj cov roj hmab hluavtaws thiab cov log tsheb kom muaj kev sib tw ntawm lub ntiaj teb thawj qib, thiab muab "pob" ntawm cov kev daws teebmeem rau cov khoom siv sab kev hloov kho thiab kev ua haujlwm zoo ntawm cov roj hmab hluavtaws. thiab cov log tsheb lag luam.
