PVC resin nrog kev ua haujlwm dav dav yog cov hmoov dawb lossis daj nrog cov txheeb ze ntawm 1.35 ~ 1.45. Lub softness thiab hardness ntawm PVC board tuaj yeem hloov kho los ntawm kev ntxiv PVC pob tshab board plasticizer. Pure PVC muaj qhov nqus dej tsawg heev thiab permeability.
PVC muaj zog hardness thiab mechanical zog, uas nce nrog qhov nce ntawm molecular hnyav thiab txo nrog qhov nce ntawm qhov kub thiab txias. Rigid PVC muaj cov khoom siv zoo, nrog rau elastic modulus ntawm 1500~3000 MPa, mos PVC nrog elasticity ntawm 1.5 ~ 15 MPa, thiab elongation ntawm tawg ntawm 200 feem pua Tsawg dua lossis sib npaug li 450 feem pua. Nws qhov kev sib txhuam kev ua tau zoo yog qhov dav, nrog kev sib txhuam zoo li qub ntawm 0.4 ~ 0.5 thiab qhov sib txhuam dynamic ntawm 0.23.
Thermal kev ua tau zoo ntawm PVC board: PVC tsis zoo thermal stability, pib decompose ntawm 140 degree, lub melting kub yog 160 degree, linear expansion coefficient yog me me thiab hluav taws-resistant, thiab oxidation index yog siab li 45.
Cov khoom siv hluav taws xob ntawm PVC board: PVC yog cov khoom siv hluav taws xob zoo, tab sis nws cov khoom ntug tsis zoo li PP thiab PE vim nws cov khoom loj. Lub dielectric tas li, dielectric poob tangent thiab ntim tsis kam yog loj, thiab corona kuj tsis zoo. Nws yog feem ntau haum rau nruab nrab, tsis tshua muaj voltage thiab tsawg zaus ntug cov ntaub ntawv.
Qhov ntawd yog txhua yam rau PVC board. Kev tiv thaiv ib puag ncig ntawm PVC tuaj yeem tiv taus feem ntau inorganic acids, alkalis, ntsev thiab feem ntau cov kuab tshuaj organic. Nws yog tsim rau cov khoom siv tshuaj thiab tshuaj tiv thaiv corrosion.
