Introduction of HPMC

Hydroxypropyl methyl cellulose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-toxic. The product can be dissolved in cold water to form a transparent viscous solution. The aqueous solution of this product has surface activity so that it has emulsification, protective colloids and relative stability. PH Stability: the aqueous solution viscosity of this product is relatively stable in the range of PH 3.0—11.0. As the product is non-ionic, and in the preparation process can be effectively purified by washing with hot water, it has a very low ash content. Hydroxypropyl methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

Physical and Chemical Properties:

1. Carbonization temperature: 280-300C

2. Density: 370-380g/l

3. Surface tension: 2% aqueous solution is 42-56dyn/cm

4. Solubility: soluble in water and some solvents, such as ethanol/water, propanol/water, etc. in appropriate proportions.

5. No ionic charge: It is non-ionic, it does not combine with metallic salts and ionic organics to form insoluble precipitates.

6. Thermal gel property: Gel will be formed when the aqueous solution of cellulose is heated to a certain temperature, and a solution will be after cooling.

7. PH value stability: it has a wide range of pH values.

8. Water retention: It has excellent water retention properties, making the moisture not easy to lose or be absorbed too quickly by the substrate. Some special grades work well in high temperature environments.

9. Thickening: its aqueous solution system has the thickening property, and the consistence is related to the viscosity of the product used and the type of compound.

10. Film formation: It can be made into a transparent, tough, soft film with excellent resistance to grease.

11. Adhesion: It can be used as a binder for tile adhesives, pigments, tobacco products, paper products, coating etc.

12. Suspension: It can prevent the precipitation of solid particles, because the formation of sediment can be inhibited.

13. Protective colloid: It can prevent small granules or particles forming a mass.

14. Emulsification: The emulsion liquid can be stabilized by reducing the surface and interfacial tension and thickening the aqueous phase.

15. Anti-sagging: It can improve the thixotropy of the product, so that the finished product does not slip even at considerate thickness.

16. Wetting ability: Cellulose has the property of wetting the substrate, no curling even if applied to a special substrate.

17. Open time: It can extend the hardening time of the product, make the raw materials fully hydrated, and improve the tensile strength and flexibility of the product.

Type and Application of Industrial Grade HPMC

Application Fields:

1.Binder: Used as a thickener and binder in the adhesive formulation.

2.Ceramic: gives lubricity, water retention and increases the original strength of the ceramic embryo.

3.Building materials: mixing into cement, so that cement mortar, plaster and gypsum ingredients have water retention properties and improve their workability.

4.Cosmetics: Regulate rheology to give
