Application of HPMC K 100
KimaCell® HPMC K 100 is commonly used as the main dispersant in the production of polyvinyl chloride. With the increase of viscosity and the decrease of hydroxypropyl content, the dispersion ability is weakened and the glue retention ability is enhanced, which leads to the increase of the average particle size and apparent density of PVC resin; The use concentration of HPMC can improve its adhesive retention ability and reduce the average particle size of the resin. The combined use of HPMC and polyvinyl alcohol can effectively improve the particle characteristics of the resin. The produced PVC resin has the characteristics of good particle shape, particle size distribution, concentrated porosity and so on.
