Chinese HPMC manufacturers cater to various industries, producing different grades of HPMC based on viscosity, polymerization degree, and solubility. The growth of end-user industries in China, such as construction and pharmaceuticals, has significantly contributed to the demand for HPMC.

At low concentrations, HEC solutions exhibit Newtonian behavior, where the viscosity remains constant regardless of the shear rate applied. However, as the concentration increases, the behavior of the solution transitions to non-Newtonian, displaying shear-thinning properties. This means that as shear is applied (for example, during mixing or pumping), the viscosity decreases, facilitating easy processing. This characteristic is particularly advantageous in industries like construction, where HEC-based slurries can be easily applied and spread before setting.

Furthermore, technological advancements in production processes may provide opportunities for cost reductions, potentially stabilizing prices in the long run. Manufacturers who invest in sustainable practices and efficient production methods may gain a competitive edge by reducing their overall costs and passing savings onto consumers.
