Product Description:
DEHA High performance aqueous PVC shortstopper is a kind of new high performance aqueous shortstopper we produce.It not only contains the components of improving the thermal stability of PVC resin, but also contains the components of fast-chain termination. When the conversion is about 80% in the synthesis reaction of PVC, or when abnormity occurs, adding the shortstopper ,the polymerization process will be terminated immediately. So it can reduce the proportion of unstable structure in PVC, improve the thermal stability and the plasticizing properties of PVC resin,avoid and reduce the attack on PVC molecules from free radicals. So it improves the whiteness and anti-aging ability of PVC resin greatly.
