It is widely used in the fields of thermal insulation mortar building materials, putty powder for interior and exterior walls, ceramics, cosmetics and latex paint coatings, pharmaceutical coating agents and slow release agents.
Industrial applications of HPMC
1. Construction
Hydroxypropyl Methyl Cellulose for Self-Leveling is used with putty powder, plaster or other building materials which can be used as good bonding materials to increase suitability and extend operating times.They are also used to adhere tiles, plastic decorations, marble, paste reinforcements and also to reduce the amount of cement used.
As a water retainer and retarder for cement mortars, HPMC makes the mortar pumpable.HPMC's ability to retain water helps to prevent cracks in the mortar and the mortar dries quickly once stains have been applied. This also improves the durability of the cured surface.
2. Coatings industry
It is used as a thickener, stabiliser and dispersant in various coating industries. Due to its ability to dissolve quickly in water or other organic solvents. It can also be used as a paint remover.
3. Polyvinyl chloride
It acts as a dispersant in the production of polyvinyl chloride, making it the main additive in the preparation of PVC for suspension polymerisation.
4. Ink printing
Due to its high solubility in water and organic solvents, HPMC is used as a dispersant, stabiliser and thickener in the ink industry.
5. Ceramic manufacturing
Used as a binder in the manufacture of ceramic products.
6. Plastics industry
Acts as an agent for the removal of moulds. It is also used as a lubricant and softening agent, etc.
7. Pharmaceutical industry
HPMC is used in the pharmaceutical industry as
Stabilizers, film materials, flat glues
Suspension aids, coating materials
Speed control polymeric materials for retardants.
8. Other
HPMC also has a wide range of applications in the following areas
- Fruit and vegetable preservation
- leather
- paper products
- textile industry.
Hebei Yibang Building Materials Co., Ltd is a large-scale professional fine chemical cellulose ether manufacturer. At present, the company's products have formed four major series of hydroxypropyl methylcellulose (HPMC), redispersible polymer powder (VAE), polypropylene PP fiber, and hydroxypropyl starch ether (HPS), with more than a dozen specifications.
The product quality rate is 100% praised and trusted by customers. It is an ISO9001: 2000 international certification enterprise. Coatings, real stone paints and other fields make the company's products more and more diverse, and continue to meet customer needs.It has introduced advanced production technology and equipment from abroad. After more than a year of preparation, in August 2010, the company introduced advanced equipment and production technology from abroad, and used domestic raw materials and regional advantages to build two non-ionic cellulose ether production lines with an annual output of 3,000 tons, which were produced by large-scale vertical reactors.
