MHEC (ไฮดรอกซีเอทิล เมทิล เซลลูโลส)

As a leading manufacturer of cellulose ethers, Peze Technology (Shijiazhuang) Co., Ltd specializes in producing premium-quality Hydroxyethyl Methyl Cellulose (HEMC) for construction and industrial applications. Hydroxyethyl methyl cellulose (HEMC) is a versatile cellulose ether widely used in construction materials due to its excellent water retention, thickening, and workability-enhancing properties. In tile adhesives, HEMC improves adhesion strength and open time, preventing tiles from slipping while allowing for adjustment during installation. Its stable viscosity ensures smooth application, even in thin-bed systems.

What is hydroxyethyl methyl cellulose used for?

Hydroxyethyl methyl cellulose (HEMC) is a cellulose ether widely used in construction materials as a multifunctional additive. It primarily improves water retention, workability, and adhesion in cement-based products like tile adhesives, renders, and self-leveling compounds. HEMC enhances mortar performance by preventing premature drying, increasing open time, and reducing cracking. Compared to HPMC, it offers better solubility in cold water and improved stability in alkaline conditions. The polymer is also used in paints, cosmetics, and pharmaceuticals as a thickener and stabilizer, valued for its non-toxic and biodegradable properties.

Applications of Hydroxyethyl Methyl Cellulose (HEMC)

In gypsum and cement-based plasters, HEMC enhances workability and reduces cracking by maintaining optimal hydration conditions. It also improves sag resistance in thick-layer applications, making it ideal for exterior renders and insulation systems.

For self-leveling underlayments, HEMC provides superior flow properties while preventing segregation of aggregates. Its water retention capability ensures uniform curing, resulting in a smooth, crack-free surface.

Beyond construction, HEMC is used in paints and coatings as a thickener and stabilizer, improving brushability and reducing splatter. In personal care products, it acts as a non-irritating viscosity modifier in shampoos, lotions, and creams.

With its excellent solubility, thermal stability, and compatibility with other additives, HEMC is a key ingredient in high-performance building materials and specialty formulations.
