PVC cable compounds yog tsim los ntawm polyvinyl chloride resin, stabilizers, plasticizers, fillers, lubricants, antioxidants, colorants, thiab lwm yam additives. Polyvinyl chloride yog ib lub polymer tsim los ntawm polymerization ntawm vinyl chloride monomers ntawm ib tug dawb-radical polymerization mechanism, pib los ntawm cov neeg ua hauj xws li peroxides los yog azo tebchaw, los yog induced los ntawm lub teeb thiab kub. Industrially tsim PVC feem ntau muaj qhov hnyav molecular li ntawm 50,000 txog 110,000; Nws tsis muaj qhov chaw melting ruaj khov, pib soften ntawm 80℃thiab 85 degree, hloov mus rau hauv lub xeev viscoelastic ntawm 130 degree, thiab pib nkag mus rau lub xeev khov ntawm 160℃thiab 180 degree.
Polyvinyl chloride nthuav tawm cov khoom siv hluav taws xob zoo- suav nrog lub zog tensile ntawm kwv yees li 60 MPa thiab qhov cuam tshuam lub zog ntawm 5 txog 10 kJ / m²- nrog rau cov khoom zoo heev dielectric. PVC cov ntaub ntawv yog cov yam ntxwv ntawm lub cev muaj zog, zoo heev nplaim retardancy, thiab tiv thaiv kev laus, tshuaj corrosion, cuam tshuam, dej, thiab roj.
