S-700 pvc resin
PVC S-700 Manufacturer: Sinopec Qilu Branch
S-700 is a high-purity PVC resin with ethylene as raw material and suspension method. It is a white
amorphous powder with particle size of 60-250 um, apparent density of 0.40-0.60 g/ml, viscosity
of dilute solution containing 0.5 g resin in 100 ml cyclohexanone of 80-160 ml/g, and plasticized
dosage absorbed by 100 g resin at room temperature of 20-30 g.
