General properties PVC resin yog xim dawb los sis lub teeb daj nrog ib tus txheeb ze ntawm 1.35 - 1.45. Lub softness thiab hardness ntawm cov khoom yuav tau tom los ntawm kev ntxiv ib lub hnab yas.
Txhua yam khoom siv hluav taws xob pwm PVC muaj kev kub ntxhov thiab cov khoom siv hluav taws xob. Thiab nws nce nrog nce ntawm molecular qhov ceeb thawj, tab sis txo nrog nce ntawm kub. Cov khoom kim heev ntawm PVC tsis ruaj zoo, thiab nws lub cev modules ncav cuag 1500-3000MPa. Cov mos mos muaj ib qho elasticity ntawm 1.5-15 MPa. Txawm li cas los, lub elongation ntawm so yog siab li 200% -450%. Cov kev sib txhuam ntawm PVC yog feem ntau, qhov kev sib txawv ntawm kev sib txhuam hauv kev sib pauv yog 0.4-0.5, thiab qhov kev sib txawv dynamic kev sib tsoo yog 0.23.
Thermal cov khoom Thermal stability ntawm PVC yog cov neeg pluag, pib decompose ntawm 140 ° C, melting kub yog 160 ° C. PVC muaj ib co coefficient ntawm linear expansion, yog nplaim retardant, thiab muaj oxidation Performance index txog li 45 los sis ntau dua. Yog li ntawd, nws yog ib qho tsim nyog ntxiv rau lub cua sov stabilizer thaum lub sij hawm ua los xyuas kom meej ntawm kev ua tiav ntawm qhov khoom.
Hluav taws xob cov pa hluav taws PVC yog ib lub tshuab hluav taws xob zoo, tiam sis vim nws lub ris tsho loj, hluav taws xob rwb tsis zoo li PP thiab PE. Dielectric tas li, dielectric poob tangent thiab ntim resistivity loj, thiab corona kuj tsis zoo, feem ntau haum rau nruab nrab thiab tsis tshua muaj hluav taws xob thiab cov ntaub ntawv tsawg zaus rwb thaiv tsev.
Environmental cov khoom PVC yog resistant to ntau cov inorganic acids, cov hauv paus, ntsev, thiab feem ntau cov organic solvents. Haum rau cov tshuaj, cov khoom siv tshuaj los tiv thaiv corrosion.
