Celopro® Cellulose ether in Polymerization

Celopro® Cellulose ether is used as a dispersing stabilizer and protective colloid in the polymerization of vinyl chloride, making the particles of the polymerization product uniform; It can also be used as an emulsifier and suspension agent for the polymerization of vinyl chloride, styrene and vinyl acetate, as well as their copolymerization.

  • HPMC for Suspension Polymerization

    HPMC for Suspension Polymerization

    Celopro® VXF is a premium Hydroxypropyl Methylcellulose (HPMC) specifically engineered as a protective colloid for the suspension polymerization of vinyl chloride monomer (VCM). With enhanced viscosity stability and superior colloidal properties, Celopro® VXF ensures the production of PVC resin with excellent particle morphology, high bulk density, and narrow particle size distribution, all essential for high-quality PVC applications.

    Applications

    Celopro® VXF is ideal for:

    • Suspension polymerization of PVC

    • Production of high-quality rigid and flexible PVC resins

    • PVC used in pipes, profiles, sheets, cables, and films

    • Formulations demanding precise particle control and bulk density

    Backed by Celotech’s advanced cellulose ether technology, Celopro® VXF offers the reliability, performance, and consistency that modern PVC suspension polymerization demands.

Commonality of Cellulose Ether

Cellulose ether is easily affected by cellulase and microorganisms. Enzymes preferentially attack the unreplaced dehydrated glucose units, which will lead to the hydrolysis of macromolecular chains and the reduction of product viscosity. Ether substituents can protect the cellulose backbone, so the stability of cellulose ether increases with the increase of DS or the uniformity of substitution, and only a few unsubstituted dehydrated glucose units are attacked by hydrolases.
