Hydroxypropyl methylcellulose HPMC for PVC pipe manufacturing as a dispersant

HPMC for PVC

1. When acting on suspension polymerization, it can reduce the interfacial tension between vinyl chloride monomer (VCM) and
water. It is conducive to the uniform and stable dispersion of VCM in the aqueous medium.
2. Prevent the coalescence of VCM droplets in the early stage of polymerization.
3. Prevent the coalescence of polymer particles in the later stage of polymerization.
4. In the suspension polymerization system, it plays the dual role of dispersion and stability protection.
5. With the increase of HPMC viscosity and the decrease of hydroxypropyl content. The interfacial tension increases and the dispersing ability decreases. Glue holding capacity is increased. The average particle size of PVC resin increases, the resin porosity decreases, and the apparent density increases.
6. Increasing the concentration of HPMC can improve its adhesive retention ability and reduce the average particle size of the resin.
