What are the different grades of HPMC?

Hydroxypropyl Methylcellulose (HPMC) is popular in different sectors. At WOTAIchem, our HPMC products are mainly applied in construction and daily chemicals. For example, wall putty, tile adhesive, self leveling, gypsum plaster, tile grout, and EIFS/ETICS.


You may find the right grade for your project needs by referring to the viscosity and corresponding applications.

What’s the difference between HPMC and MHEC/HEMC?

HPMC at around 60°C~75°C and HEMC >80°C normally. It depends on different production technologies as well. In summer, HEMC water retention capacity remains the same viscosity and dosage, especially in India. HPMC with lower gel temperature will lose thickening and water retention effect in a hot environment. Therefore accelerating the hardening of mortar.


HPMC uses fine cotton as raw material to go through the alkalization process. Plus etherification agents propylene oxide and methyl chloride. Then formulated into a non-ionic cellulose ether HPMC.


The production process of MHEC/HEMC is similar to that of HPMC. The only difference is etherification agents. Instead of propylene oxide and methyl chloride, HEMC uses ethylene oxide and methyl chloride. Ethylene oxide requires more advanced production technology. Due to its storage condition, risk control, and fewer manufacturers, the price of HEMC is higher.
