Hydroxypropyl methyl cellulose is a semi synthetic, inactive, and viscoelastic polymer commonly used in ophthalmology as a lubricant, or as an excipient or shaping agent in oral medicine. It is commonly found in various types of commodities.
1. Polyvinyl chloride: Used as a dispersant in the production of polyvinyl chloride, it is the main auxiliary agent for suspension polymerization to prepare PVC.
2. Construction industry: As a water retaining agent and retarder for cement mortar, it makes the mortar pumpable. When using mortar, gypsum, putty powder, or other building materials as adhesives, it can improve the applicability and extend the operational time. Used for pasting ceramic tiles, marble, plastic decorations, pasting reinforcing agents, and can also reduce the amount of cement used. The water retention performance of HPMC prevents the slurry from cracking due to drying too quickly after application, enhancing the strength after hardening.
3. Plastics: used as forming release agents, softeners, lubricants, etc.
4. Ceramic manufacturing industry: Hydroxypropyl methylcellulose is widely used as a binder in ceramic product manufacturing.
5. Coatings industry: As a thickener, dispersant, and stabilizer in the coatings industry, it has good solubility in water or organic solvents. As a paint remover.
6. Ink printing: Hydroxypropyl methylcellulose is used as a thickener, dispersant, and stabilizer in the ink industry, and has good solubility in water or organic solvents.
7. Pharmaceutical industry: coating materials; Membrane material; Control rate polymer materials for sustained-release formulations; Stabilizer; Suspension aids; Tablet adhesive; Thickener.
8. Other: This product is also widely used in leather, paper products, fruit and vegetable preservation, and textile industries.
Hydroxypropyl methyl cellulose is used as a thickener, dispersant, binder, excipient, oil resistant coating, filler, emulsifier, and stabilizer in the textile industry. It is also widely used in industries such as synthetic resins, petrochemicals, ceramics, papermaking, leather, pharmaceuticals, food, and cosmetics.
