HEMC is a cellulose ether different from HPMC. The substituents of HEMC are hydroxypropyl and methoxy. Compared with HPMC, HEMC has more hydrophilic groups, which means that it has a relatively high gel temperature, better water retention in a hot environment, and better thermal stability.
Construction Industry
Used as a thickener and water retainer for products, improving product processing and strength, reducing cracking and shrinkage.
Personal Care
Used as a thickener and stabilizer for various personal care products, improving product ductility and foaming properties.
Paints and Coatings
Used as a thickener, stabilizer and film former to improve product viscosity and fluidity, and enhance coating adhesion and durability.
Adhesives and Sealants
Used as a thickener and water retainer to provide products with better processing and adhesion.

How do I choose the right HEMC viscosity for my application?
When selecting HEMC viscosity, consider the specific requirements of the application, such as desired consistency, water retention, and overall performance.
How are HEMC grades differentiated?
HEMC grades are differentiated based on their viscosity, which is usually measured in mPa·s (milliPascal seconds) or cP (centipoise). Different grades offer different performance characteristics, such as water retention, solubility, and thickening ability.
How do I choose the right HEMC variety?
When selecting HEMC, consider the specific application areas and performance requirements, including viscosity, solubility, and water retention.
Can I combine HEMC with other cellulose ethers in one application?
Yes, HEMC can be combined with other cellulose ethers, such as HPMC or HEC, to achieve the desired performance in a specific application. The compatibility and performance of the combined products should be tested before use to ensure the best results.
Can I use HEMC with different types of cement?
Yes, HEMC is compatible with various types of cement, including Portland cement, slag cement, and fly ash cement. Its benefits and performance may vary slightly depending on the cement type and formulation.
Is HEMC environmentally friendly?
HEMC is biodegradable and has minimal impact on the environment during use and disposal, making it an environmentally friendly material.
