Hydroxypropyl methylcellulose HPMC is widely used in building materials, coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco, and other industries. HPMC can be divided into building level, food level, and medical level according to its use.
At present, most of the domestic products are of construction grade. In the construction grade, the amount of putty powder is very large, about 90% of which is used as putty powder, and the rest is used as cement mortar and glue.
Let me check the main hydroxypropyl methylcellulose uses below:
- Construction industry: HPMC used as the water-retaining agent and retarder in cement mortar, makes it can be pumped. Used in plastering mortar, gypsum, putty powder or other building materials as adhesive, which can improve the daubing performance and extend the operation time. HPMC cellulose ether can be used to paste ceramic tile, marble, and plastic decoration, paste reinforcing agent, and reduce cement consumption. The HPMC property of water retention makes the paste not crack after coating because of drying too fast and enhances the strength after hardening.
- Ceramic manufacturing industry: hydroxypropylmethylcellulose is widely used as adhesive in ceramic product manufacturing.
- Coating industry: HPMC used as thickener, dispersant, and stabilizer in the coating industry, HPMC solubility is good in water or organic solvent.
- Ink printing: as thickener, dispersant, and stabilizer in the ink industry, it has good solubility in water or organic solvent.
Plastic: used as a mold release agent, softener, lubricant, etc.
- PVC: as a dispersant in PVC production, HPMC cellulose is the main auxiliary for PVC preparation by suspension polymerization.
- Others: This product is also widely used in leather, paper products, fruits and vegetable preservation, and textile industry.
- Pharmaceutical industry: coating materials; membrane materials; speed control polymer materials for sustained-release preparations; stabilizers; suspension AIDS; tablet adhesives; tackifiers.
Our products are mainly used for the construction industry
- Cement mortar: improve the dispersion of cement sand, greatly improve the plasticity and water retention of mortar, have an effect on preventing cracks, and enhance the strength of cement.
- Ceramic tile cement: improve the plasticity and water retention of pressed ceramic tile mortar, improve the adhesive force of ceramic tile, and prevent pulverization.
- Coating of refractory materials such as asbestos: as suspension safety agent, liquidity improver, and also improve the adhesive force to the base.
- Gypsum concrete: improve water retention and processability, and improve the adhesion to the substrate.
- Joint cement: Hydroxypropyl methylcellulose HPMC is added to the joint cement for the gypsum board to improve the fluidity and water retention.
- Emulsion putty: HPMC products can improve the fluidity and water retention of putty based on resin latex.
- Stucco: as a paste instead of natural substances, it can improve water retention and improve the adhesive force with the substrate.
- Coating: as the plasticizer of latex coating, it can improve the operation performance and fluidity of coating and putty powder.
- Spray coating: it has a good effect on preventing the cement system or latex system from sinking, improving the fluidity and spray pattern.
- Secondary products of cement and gypsum: HPMC used with gypsum retarder as the press out molding binder of cement asbestos series and other hydraulic substances, to improve the fluidity and obtain uniform molding products.
- Fiber wall: due to the anti enzyme and anti-bacteria effect, it is effective as the adhesive of the sand wall.
- Others: it can be used as a bubble retention agent (PC version) for thin mortar and mud hydraulic operators.
HPMC is widely used in many industries. In China, there are man cellulose ether manufacturers and the HPMC quality is different. Michem is one of the leading factories that have produced cellulose ether for many years and you can send us an inquiry for the lasted cellulose ether price.
What is HPMC? HPMC is a kind of chemical of construction.
