Nqus blister tshuab blister khoom PVC muaj ntau lawm

Qhov hnyav molecular ntawm industrially tsim PVC yog feem ntau nyob rau hauv thaj tsam ntawm 50, 000 mus rau 110, 000, nrog ib tug loj polydispersity, thiab molecular hnyav nce nrog rau qhov txo ntawm lub polymerization kub; tsis muaj qhov chaw melting ruaj khov, nws pib muag ntawm 80-85 degree , thiab dhau los ua viscoelastic ntawm 130 degree , 160 ~ 180 degree pib hloov mus rau hauv lub xeev dej khov; zoo txhua yam khoom, tensile lub zog ntawm txog 60MPa, cuam tshuam lub zog ntawm 5 ~ 10kJ / m2; zoo heev dielectric zog.
