PVC

Product Features: Dispersion: Excellent suspension dispersion performance, by adjusting the surface tension and concentration, the monomer will be dispersed into fine particles. Suspension: improve resin thermal stability and control particle size distribution, improve particle shape and viscosity distribution, reduce the incidence of fisheye. Adsorbability: improve the quality of resin and processed products, so that PVC resin to produce a certain void, enhance the absorption of plasticizer.

PVC polymerization system prepared by high quality HPMC, in addition to ensure that the performance meets international standards, but also has good apparent physical properties, excellent particle properties and excellent melt rheological behavior. In the compound dispersant system, polyvinyl alcohol (PVA) with different degrees of alcoholysis and polymerization and hydroxypropyl methylcellulose (HPMC) compound collocation is better, which is conducive to the porosity of the resin, and the absorption of plasticizer is also beneficial.
