HPMC E 50
EipponCellHPMC E 50 Hydroxypropyl methylcellulose is a prominent type of dispersant used in the polyvinyl chloride (PVC) industry. It is utilized during the suspension polymerization of vinyl chloride to effectively reduce the interfacial tension between vinyl chloride monomer (VCM) and water. This reduction in tension helps to uniformly and stably disperse the VCM within the water medium. Additionally, it aids in preventing the merging of VCM droplets at the onset of the polymerization process and inhibits coalescence between polymer particles in the intermediate and later stages. In the suspension polymerization system, EipponCellHPMC E 50 Hydroxypropyl methylcellulose serves a dual purpose of dispersion and stability protection.

HPMC F 50
EipponCellHPMC F 50, a hydroxypropyl methyl cellulose, functions as a dispersant in the PVC industry. In the suspension polymerization process of vinyl chloride, commonly used dispersants include polymer compounds such as polyvinyl alcohol and cellulose ether. When subjected to stirring, they facilitate the formation of droplets with suitable sizes. This capability is referred to as the dispersing ability of the dispersant. Additionally, the dispersant is adsorbed onto the surface of the vinyl chloride monomer droplets, forming a protective layer that prevents droplet aggregation and stabilizes them. This effect is known as the colloid retention ability of the dispersant.
