Physical Properties
1, Appearance: HEMC is white or off-white fibrous or granular powder; odorless.
2, Solubility: HEMC in the H model can be dissolved in both cold water and hot water, L model can only be dissolved in cold water, HEMC insoluble in most organic solvents. HEMC by surface treatment in cold water dispersion is not cohesive, dissolution is slow, but its pH modulation 8 ~ 10 can be quickly dissolved.
3, Ph stability: pH value in the range of 2 ~ 12 viscosity changes are small, more than this range of viscosity decreases.
4, Particle size: 40 mesh pass rate 99%, 80 mesh pass rate 100%.
5、Sight density: 0.30-0.60g/m3.
6, HEMC has the characteristics of thickening, suspension, dispersion, adhesion, emulsification, film-forming, water retention, etc., and its water retention is stronger than that of methyl cellulose, viscosity stability, anti-mold, dispersion is stronger than that of hydroxyethyl cellulose.
Product Applications
1.Tile Adhesive
（1） It saves working time by making dry mixing ingredients easy to mix without agglomeration, and improves workability and reduces cost due to faster and more effective application.
（2） Improves tiling efficiency by extending cool-down time. Provides excellent adhesion.
（3）A specially developed model with high anti-slip properties is available.
2.Self-leveling flooring material
（1）Provides viscosity and can be used as an anti-settling Additive.
（2）Enhances flowability and pumpability, thereby improving the efficiency of flooring.
（3）Controls water retention, thereby greatly reducing cracking and shrinkage.
3.Water-based coatings and paint removers
（1） Prolongs storage period by preventing solids from settling. Excellent compatibility with other components and high biostability.
（2）Dissolves quickly and without agglomerates, helping to simplify the mixing process. Cold water dispersible models allow for faster and easier mixing without agglomerates.
（3） Produces favorable flow characteristics, including low spattering and good leveling, which ensures excellent surface finish and stops paint droop.
（4）Enhances the viscosity of water-based paint removers and organic solvent removers so that the paint remover does not run off the surface of the workpiece.
3.Extruded Concrete Sheets
（1） Enhance the processability of extruded products with high bonding strength and lubricity.
（2）Improve the wet strength and adhesion of the sheet after extrusion.
Company information
The company's main import and export products include
（1）Petrochemicals：Refers to the use of oil or natural gas as raw materials, the manufacture of chemicals in the petrochemical industry of manufactured products, the same called petrochemical products.
（2）Flavors and Fragrances：Fragrance: some from the natural world of plants and animals or by artificial single separate, synthetic and get the fragrance material called fragrance. Flavour: Flavour is a mixture of a variety of fragrances (sometimes also containing a certain amount of solvent) blended out of a certain aroma, can be used directly for product fragrance, can be widely used in perfumes, cosmetics, shower gels and other daily necessities. Simply put, flavours are made from a mixture of various fragrances.
（3）Polymers：The advantage of Polymers is that they can be easily formed into the desired shape using a variety of techniques such as solution casting, melt moulding, or machining. As a result, polymer-based implants are relatively inexpensive to manufacture. Polymers can also react so that different chemical molecules can attach to the surface of the implant, making it more compatible with the body's surroundings.
