Hydroxypropyl methylcellulose (HPMC): 

* The most widely used cellulose ether in the construction industry

* Balanced water retention and thickening properties

* Excellent cost-performance ratio and wide applicability

Carboxymethyl cellulose (CMC):

* The most competitively priced cellulose product

* High transparency of aqueous solutions

* Irreplaceable in specific applications

Hydroxyethyl cellulose (HEC):

* A cellulose ether with excellent water retention properties

* Good biocompatibility

Primarily used in high-end applications

Methylhydroxyethyl cellulose (MHEC):

* An upgraded version of HPMC

* Even better overall performance

* Higher gel temperature and wider applicability

Comparison of Solubility

HEC: Fastest dissolving speed, dissolves quickly even in cold water.

CMC: Dissolves relatively quickly, but requires thorough stirring.

MHEC: Excellent solubility, does not easily clump.

HPMC: Moderate dissolving speed, requires a certain amount of stirring time.

Water Retention Capacity Ranking

HEC: Highest water retention rate, reaching over 98%.

MHEC: Excellent water retention, stable at high temperatures.

HPMC: Good water retention, meets most needs.

CMC: Moderate water retention, greatly affected by pH value.

Thickening Effect Comparison

HPMC: Significant thickening effect, high cost-effectiveness.

MHEC: Higher thickening efficiency, more economical dosage.

CMC: Moderate thickening ability, significant price advantage.

HEC: Relatively mild thickening effect.

Differences in Temperature Resistance

MHEC: Highest gel temperature (75-85℃).

HEC: Gel temperature approximately 70-80℃.

HPMC: Gel temperature approximately 60-70℃.

CMC: Relatively poor temperature resistance.
