Uses of HPMC
Industrial grade HPMC, the main use is polyvinyl chloride production as a dispersant, is the main additive for the preparation of PVC by suspension polymerization. In addition, in the production of other petrochemical, coatings, building materials, paint remover, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products as thickeners, stabilizers, emulsifiers, excipients, water retention agents, film forming agents, etc. In the application of synthetic resin, the obtained products can have the characteristics of regular particles, looseness, suitable specific gravity, and excellent processing performance, thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used in mechanized construction such as wall masonry, stucco stucco, etc.; Especially in decorative construction, it is used as pasting tiles, marble, plastic decoration, with high pasting strength and reducing the amount of cement. Used as a thickener in the coating industry, it can make the layer bright and delicate, not depowdered, and improve leveling performance.
Main uses
1. Construction industry: as a water retaining agent and retarder for cement mortar, the mortar has pumpability. In plaster, gypsum, putty powder or other building materials as an adhesive, improve spreadability and prolong operable time. Used as pasting tiles, marble, plastic decoration, paste enhancer, but also can reduce the amount of cement. The water retention properties of HPMC prevent the slurry from cracking due to drying too quickly after application, enhancing the strength after hardening.
2. Ceramic manufacturing industry: widely used as adhesive in the manufacture of ceramic products.
3. Coating industry: as a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. As a paint stripper.
4. Ink printing: as a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
5. Plastic: as forming release agent, softener, lubricant, etc.
6. Polyvinyl chloride: a dispersant in the production of polyvinyl chloride, which is the main additive for the preparation of PVC by suspension polymerization.
7. Others: This product is also widely used in leather, paper products industry, fruit and vegetable preservation and textile industry.
8. Pharmaceutical industry: coating materials; membranes; Rate-controlled polymer materials for sustained-release formulations; stabilizers; suspension; tablet adhesives; Tackifier
