Mellutel YT-50 Applied to PVC Features

1, During suspension polymerization, limit the interfacial tension between vinyl chloride monomer (VCM) and water, and assist VCM to be evenly and stably dispersed in the aqueous medium.

2, Prevent the coalescence of VCM droplets at the preliminary stage of polymerization.

3, Prevent coalescence between polymer particles in the later stage of the polymerization process.

4, In the suspension polymerization system, it performs a twin function of dispersion and balance protection.

5, With the extend of HPMC viscosity and the reduce of hydroxypropyl content, the interfacial anxiety increases, the dispersion potential decreases, the glue retention capability increases, the common particle measurement of PVC resin increases, the resin porosity decreases, and the obvious density increases.

6, Increasing the attention of HPMC can enhance its glue retention ability and minimize the common particle measurement of the resin.
