HEMC/MHEC, also known as Methyl Hydroxyethyl Cellulose, is a non-ionic cellulose ether, made from natural cellulose by chemical modification. HEMC is an odorless, tasteless, non-toxic white powder that swells to a clear or slightly turbid colloidal solution in cold water.
HEMC excels inwater retention, gel temperature, thickening, and film formation.
Michem HEMC is widely used in building materials,cosmetic, coating, ceramic and textile industries.
Michem is a professional manufacturer and supplier of hydroxyethyl methyl cellulose in China. We are committed to researching and developing high-performance hydroxyethyl methylcellulose powder.
We are committed to delivering superior-quality hydroxyethyl methyl cellulose that is sustainable and cost-effective.

Methyl Hydroxyethyl Cellulose improves the anti-slip properties of tile adhesives and prevents tiles from sliding during the adhesion process.
Michem HEMC ensures the skim coat’s workability and offers smooth wall surfaces.
Adding the proper amount of HEMC improves the workability of gypsum-based materials, making them easier to work with and apply.
HEMC can improve the bond strength of insulation mortar and bonding mortar and reduce the phenomenon of shedding of EIFS (Exterior Insulation Finishing System).
The water retention capacity of HEMC helps in reducing the shrinkage and cracking of tile grout.
Our production base is located in Jinan, Shandong Province. The factory uses advanced production equipment and environmental protection technologies to ensure the quality of cellulose ether and the green and sustainable production process.
The whole process of cellulose ether production adopts an automated control system, which reduces manual intervention and improves the precision and stability of production.
The closed production system reduces the leakage of dust and harmful gases, protecting the health of workers and the environmen
We have 6 fully equipped laboratories for cellulose ether product development, quality control, and performance optimization.
The labs will simulate actual application scenarios to test the performance of cellulose ethers in construction, detergents, and oil drilling.
In addition, our laboratories are constantly developing new products and applications, improving existing products, and providing customized formulations according to customer needs.
Michem cellulose ether products are packaged in moisture-proof and dust-proof packaging to ensure product safety.
Shipping Services: Fast global sea freight, real-time tracking, and support for designated logistics.
HEMC is an environmentally friendly material. It is made of natural cellulose, non-toxic, harmless, biodegradable, and environmentally friendly.
It is recommended that MHEC be stored in a dry, cool environment, sealed, and protected from moisture and high temperatures.
HEMC can be compatible with other additives (e.g. PCE powder, powder defoamers, redispersible polymer powder), but compatibility tests need to be carried out according to the specific formulation to ensure stable performance.
Avoid adding directly to hot water or mixing with other powders to avoid caking.
Add a small amount of dispersant (e.g. ethanol) immediately after stopping mixing, or change to pre-dispersion with cold water and mix gradually. The lumps can be sieved and re-dissolved.
