HPMC is non-ionic cellulose ether, appearance is white powder, odorless and tasteless, soluble in water and most polar organic solvent and suitable proportion of ethanol / water, propanol / water, two trichloroethane, insoluble in ether, acetone, ethanol, in cold water swelling into colloidal solution clear or slightly turbidity. Aqueous solution with surface activity, high transparency, […]

HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural hIgh molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.

CMC and HPMC can be added to mortar to maintain moisture and thickening.As the dosage increases, the level of mortar will be reduced.CMC is an ionic cellulose ether that can react with the Ca (OH) 2 when added to the mortar.There is no obvious improvement in the water retention performance of CMC,

HPMC  advantages and application

External thermal insulation system-choosing an appropriate amount of HPMC can maximize the bonding strength and smooth construction of the bonding mortar, and improve work efficiency.

Tile adhesive-HPMC’s good water retention, enhanced adhesion,

The viscosity of HPMC is inversely proportional to temperature, that is, the viscosity increases as the temperature decreases. We usually say that the viscosity of a product refers to the result of testing its 2% aqueous solution at a temperature of 20 degrees Celsius.

Instant HPMC disperses quickly in cold water and disappears in the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water without real dissolution. In about 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid.

1. The pure HPMC is in a fluffy visual state, with a small bulk density, ranging from 0.3-0.4g/ml; adulterated HPMC has better fluidity and feels heavier, which is obviously different from the original appearance.

2. The aqueous solution is clear and has high light transmittance, and the water retention rate is ≥97%; the adulterated HPMC water solution is turbid, and the water retention rate is difficult to reach 80%.

Cellulose ether HPMC will prolong the setting time of cement paste or mortar and delay the hydration kinetics of cement, which is beneficial to increase the operation time of cement-based materials, improve the consistency of mortar and the loss of concrete slump over time, but it is also possible It will delay the construction progress, especially the mortar and concrete used in low temperature environment.
