Hluav taws xob hla kev sib txuas yog kev siv hluav taws xob muaj hluav taws xob ntau ntawm cov khoom siv hluav taws xob tsim hluav taws xob tsim hluav taws xob los tsim hluav taws xob dawb hauv cov kab hluav taws xob polyethylene polymer. Cov dawb radicals muaj kev sib txuam nrog sib luag thiab sib txuas ua ke los tsim lub ntsej muag sib npaug ntawm cov network molecular qauv los ua qhov sib txuas. Cov qauv kev sib txuas tsis tas yuav kub thiab dej, tuaj yeem sib txuas ntawm cov polyethylene tsis cuam tshuam cov nplaim taws thiab cov khoom hluav taws xob.
Hluav taws xob hla sib txuas siv feem ntau yog siv rau cov khoom sib txuas xov hluav taws xob xws li kub tsis kam, cov hluav taws kub halogen tsis muaj nplaim taws, thiab lwm yam, feem ntau, cov tshuaj tiv thaiv lossis cov neeg sawv cev yuav tsum tau siv ua ke. Kev ntsuas hluav taws xob hla kev sib txuas yuav ua tau nyob hauv qhov kub thiab txias, thiab qhov ntsuas ntawm qhov sib txuas thiab cov duab txuas sib txuas tau yooj yim tswj tau los ntawm kev tswj hwm qhov koob tshuaj, thiab tsis muaj khib nyiab tom qab kev sib txuas, uas yog mus rau ntsuab hla kev txuas cov txheej txheem. Tib lub sijhawm, hla-txuas Lub efficiency tseem yog qhov ntau. Txawm li cas los xij, hluav taws xob hla sib txuas yuav tsum tau yuav khoom siv hluav taws xob ntxiv, uas yuav ua rau cov nqi nce ntxiv.
