Dual phab ntsa cua sov shrink tubing yog ua los ntawm cov zoo polymer ( txheej txheej) nrog kub yaj nplaum ( puab txheej ).Lub tshav kub shrink tubing tiv thaiv cov dej noo thiab corrosive ib puag ncig, thaum muab hluav taws xob rwb thaiv tsev thiab kev tiv thaiv txhua yam. Thaum lub sij hawm installation, cov ntaub nplaum muaj nyob rau hauv lub tshav kub shrink tubing melts thiab faib thoob plaws hauv lub lined cheeb tsam tsim ib tug tiv thaiv, dej-resistant barrier. Thaum nws txias, txheej sab hauv tsim ib txheej adhesion ntawm cov tubing thiab cov khoom siv los yog hlau. Muab cov dej-nruj kaw ntom nti thiab tiv thaiv rau cov khoom sib txuas lossis cov xov hlau.Qhov kub ua haujlwm tas mus li yog haum rau Minus 55° C rau 125 ° C. Kuj tseem muaj qib tub rog-tus qauv nrog qhov siab tshaj plaws ua haujlwm kub ntawm 135 ° C. Ob qho tib si 3: 1 thiab 4: 1 shrink ratio yog zoo.
