Cov khoom siv roj hmab yog cov ntaub ntawv elastic ua los ntawm cov roj hmab ntuj, cov roj hmab hluavtaws, thiab cov roj hmab rov qab los ntawm cov txheej txheem xws li calendering, extrusion molding, thiab compression molding.
Lawv feem ntau suav nrog cov log tsheb, hoses, thiab cov ntsaws ruaj ruaj. Cov txheej txheem ntau lawm suav nrog plasticizing, sib tov, molding, thiab vulcanization, nrog vulcanization yog txheej txheem tseem ceeb uas imparts elasticity.
Cov txheej txheem no yuav tsum muaj cov chaw tswj kev ua qias tuaj los kho qhov tsis zoo ntawm cov organic compound (VOC) emissions.
