【Introduction】
SPJ-HZ Oil soluble terminator The terminator used in polymerization of PVC resin production can rapidly and uniformly enter the polymerization system, terminate unreacted free radical, stabilize PVC, and improve whiteness and thermal stability of PVC resin.
SPJ-HZ Oil soluble terminator It will copolymerize with PVC after use, to improve plasticizing property of resin as well as surface cleanliness, impract resistance, surface properties of products, and reduce plasticizing temperature and fish eyes.

Generally when polymerization pressure is the pressure drop of 0.05 ~ 0.05 MPa can join SPJ - HZ (depending on the GeChang process conditions).
Join the amount of monomer into the kettle 0.035 ~ 0.055% should be according to the process in the resin type, Initiator varieties, different amounts of monomer inputs make proper adjustment, choose to best quantity.
