Used as thickener, dispersant, water retention agent and air-entraining agent etc. Mainly used in cement and gypsum based dry mix mortar to increase bond strength, workability, and water retention. Reduce water loss on concrete surface, preventing cracks and increase scrape area. It is widely used in wall plaster and tile adhesive products

In paints, as a protective colloid, HPMC and MHEC can be used in the polymerization of vinyl acetate emulsion to improve the stability of the polymerization system in a wide pH range. Use pigments, fillers and other additives in finished product manufacturing to evenly disperse, stabilize and provide thickening effect.

2.The difference between HPMC and MHEC: Thermal Stability

Thermal stability of HPMC and MHEC is affected by their gel temperature.

In general, the gel temperature of HPMC is around 60&#;-75&#; depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80&#;. Therefore its stability under high temperature is better that HPMC. In practical construction, in the hot construction environment in summer, the water holding capacity of MHEC with the same viscosity and dosage is better than that of HPMC. Especially in the Southeast Asian countries and India, mortar will sometimes be constructed at high temperature. Cellulose ether with low gel temperature will lose its thickening and water retention at high temperature, thereby accelerating the hardening of mortar, and affects the construction.

On the other hand, because there are more hydrophilic groups in the structure of MHEC, it has better hydrophilicity. The water retention rate of MHEC in mortar is a little higher than HPMC at the same dosage of products with the same viscosity.

What is the difference between MHEC and HPMC chemicals? How to distinguish them? This video focus on etherizing agent, uses, price, and thermal stability (gel temperature). You can get very clear insight. In part 6 of this 7 things you need to know to buy HPMC for tile adhesive, we also covered this in detail, such as manufacture process, physical and chemical properties, cellulose ether group content ...

NO.1 Difference between MHEC and HPMC etherizing agent

This is the biggest difference between MHEC and HPMC.

So what is the etherizing agent of HEMC? It is monochlomethane and ethylene oxide. Its full name is Hydroxyethyl methyl cellulose,

And what is the authorizing agent of HPMC? That is monochloromethane and propylene oxide.  Its full name is hydroxypropyl methylcellulose. it's synonyms is hypromellose.

NO.2 Difference between MHEC and HPMC gel temperature

So the gel temperature of HEMC is higher than HPMC.  The gel temperature of HEMC of MIKEM Chemical mainly is around 75° to 100°. And that of HPMC is around 55° to 75°. So if you're living in somewhere some countries that is of higher temperature like India, Indonesia or Africa. These countries of a higher temperature performance environment. You should choose HEMC for your worksite, all right?

NO.3 Difference between MHEC and HPMC uses

HEMC is mostly using liquid production like water-based coatings, wall putty...

But HPMC is mainly using construction like dry mortar, putty powder...

NO.4 Difference between MHEC and HPMC price

Generally speaking, HEMC price is a little more expensive than HPMC. The main difference is what you care about.

Okay, so that's all about today. Mainly we're talking about MHEC and HPMC and their difference. I hope you have some knowledge. About HPMC and HEC, they also have differences.
