Kev ua haujlwm dav dav PVC cob yog cov hmoov dawb lossis lub teeb daj nrog cov txheeb ze ntawm 1.35-1.45. Lub hardness thiab softness ntawm cov khoom tuaj yeem hloov kho los ntawm kev ntxiv plasticizer.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, PVC board muaj siab hardness thiab mechanical zog. Thiab nws tau nce nrog qhov nce ntawm qhov hnyav molecular, tab sis txo qis nrog qhov nce ntawm qhov kub thiab txias. Rigid PVC muaj cov khoom siv zoo, thiab nws cov qauv elastic tuaj yeem ncav cuag {{0}}mpa. Lub elasticity ntawm mos PVC yog 1.5-15 MPa. Tab sis qhov elongation ntawm so yog siab li 200 feem pua -450 feem pua . Kev sib txhuam ntawm PVC yog qhov dav, qhov sib txhuam zoo li qub yog 0.
Nyob rau hauv cov nqe lus ntawm thermal zog, thermal stability ntawm PVC board yog heev tsis zoo. Nws pib decompose ntawm 140 degree thiab melting kub yog 160 degree. PVC muaj ib tug me me coefficient ntawm linear expansion, yog nplaim retardant, thiab nws oxidation Performance index yog ntau tshaj 45. Yog li ntawd, nws yog tsim nyog los ntxiv kub stabilizer nyob rau hauv cov txheej txheem los xyuas kom meej cov kev ua tau zoo ntawm cov khoom.
Hais txog cov khoom siv hluav taws xob, PVC board yog cov khoom siv hluav taws xob zoo, tab sis nws cov hluav taws xob rwb thaiv tsev tsis zoo li PP thiab PE vim nws cov polarity loj. Lub dielectric tas li, dielectric poob tangent thiab ntim resistivity yog loj, thiab corona kuj tsis zoo. Nws yog feem ntau haum rau nruab nrab thiab tsawg voltage thiab tsawg zaus insulating cov ntaub ntawv.
Nyob rau hauv cov nqe lus ntawm ib puag ncig kev ua tau zoo, PVC board muaj peev xwm tiv taus feem ntau inorganic acids, alkalis, ntsev thiab feem ntau cov organic solvents. Haum rau cov khoom siv tshuaj thiab tshuaj tiv thaiv corrosion.
