Hydroxy Ethyl Methyl Cellulose

Hydroxy Ethyl Methyl Cellulose

Description:

Because HPMC contains hydroxyethyl, the gel temperature of the product reaches 60-90 ° C. In addition, hydroxyethyl has high hydrophilicity, which also makes the product have a good water retention rate. Especially in the hot and hot summer construction, the water retention of HEMC is higher than that of methylcellulose of the same viscosity, and the water retention is not less than 85%.

Application:

HPMC is widely used in water-based latex coatings, building extrusion profiles, biologics, printing inks, oil drilling, etc. to play a role of thickening and retaining water. It is used as a cementing agent, water retaining agent for cement, gypsum, lime, and is a powder building material Excellent admixture. Used in construction dry powder mortar flexural strength ≥3.0Mpa; compressive strength ≥8.0Mpa
