Function:
Hydroxypropyl methyl cellulose (HPMC) is one of the non-ionic cellulose mixed ethers. It is a semi synthetic, inactive, viscoelastic polymer, mainly used as thickener, dispersant, binder, excipient, oil resistant coating, filler, emulsifier and stabilizer in the textile industry. It is also widely used in synthetic resin, petrochemical industry, ceramics, paper making, leather, medicine, food, cosmetics and other industries.
Application:
- Construction industry: as the water retaining agent and retarder of cement mortar, the mortar has pumping property. Plaster mortar, gypsum material, putty powder or other building materials as the adhesive to improve the smearability and prolong the operation time. It can be used to paste ceramic tile, marble, plastic decoration, paste reinforcing agent, and reduce cement consumption. The water retention property of HPMC makes the slurry not crack due to too fast drying after application, and enhances the strength after hardening.
- Ceramic manufacturing industry: widely used as adhesive in ceramic product manufacturing.
- Paint industry: As a thickener, dispersant and stabilizer in the paint industry, it has good compatibility in water or organic solvents. As a paint remover.
- Ink printing: As a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
- Plastics: used as forming release agent, softener, lubricant, etc.
- PVC: used as dispersant in PVC production, it is the main auxiliary for suspension polymerization to prepare PVC.
- Others: This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.
- Pharmaceutical industry: coating materials; Membrane material; Controlled speed polymer material of sustained release preparation; Stabilizer; Suspension aids; Tablet adhesive; Tackifier.
Storage:
Pay attention to sun protection, rain protection and moisture protection, avoid direct sunlight, and store in a dry place.
