Hydroxypropyl methyl cellulose can be dissolved in cold water to form a transparent viscous solution.
Hydroxypropyl methyl cellulose is a white or slightly yellowish powder, and odorless, tasteless, non-toxic
organic solvents dissolved: As with a certain amount of hydrophobic methoxy-, so the goods can be dissolved in some organic solvents can also be dissolved in a mixture of water and organic solvents.
Salt Tolerance: As the goods of non-ionic and non-polymer electrolyte, therefore, it is metal salts or organic electrolytes are relatively stable in aqueous solution.
Surfactants: In this product, the aqueous solution with surfactant, it has a role in emulsion, protective colloid and relative stability.
The role of thermal gelation: When heated to a certain temperature above the aqueous solution when the goods to become opaque to generate precipitation, so that the loss of viscosity of the solution. But it then gradually cooling the solution into the original state. Condensation and precipitation temperature of the decision appears in the type of product, solution concentration and heating rate.
Low ash content: As a non-ionic materials in the preparation of hot water washing can be effective in refining, so its very low ash content.
PH Stability: This product is the viscosity of aqueous solution in the framework of PH3.0-11.0 are relatively stable.
Role in retention: As this product is hydrophilic and it is a high-viscosity aqueous solution. It added to the mortar, plaster, paint, etc., in the products in the role of maintaining a high level of water.
Shape to maintain: in comparison with other water-soluble polymer, the products of the aqueous solution of the viscoelastic properties of a special. The addition of its ceramic products to improve the extrusion of the ability to shape change.
Lubrication: Add this product to reduce the friction coefficient and improve the extrusion of ceramic products, cement products and lubricity.
Film-forming: This product can generate strong flexible, transparent sheet, and a good performance of oil-resistant ester .
