Many mortar and putty powder companies use hydroxypropyl methyl cellulose as a chemical raw material. Some customers are not very clear about which viscosity HPMC white powder to choose. There are some hydroxypropyl methyl cellulose on the market. 4W-5W low viscosity HPMC white powder, there are also 10W, 15W, 20W high viscosity HPMC white powder. Let's take a look at how various industries should choose hydroxypropyl methyl cellulose.

How to choose the right hydroxypropyl methyl cellulose (HPMC) for different purposes?

Let me first introduce the requirements for the viscosity of HPMC white powder in cement mortar.

Cement mortar: If hydroxypropyl methyl cellulose is used in cement mortar, the requirements for viscosity will be higher. Generally, hydroxypropyl methyl cellulose with a viscosity of 10W-20W should be selected because of this viscosity. Base methyl cellulose can be used as a water-retaining agent and retarder to make the mortar pumpable, so that the cement mortar will not crack due to drying too fast after being applied, and increase the strength after hardening.

Therefore, when purchasing, you must confirm with the supplier what the viscosity of HPMC white powder is, what price corresponds to what quality, and don’t just look at low prices, because all the prices of products are consistent with Its cost , the price of hydroxypropyl methyl cellulose is too low, and the viscosity will definitely decrease. If the viscosity decreases, the use will increase accordingly
