The product information of hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose (HPMC) CAS:9004-65-3

Hydroxypropyl methylcellulose (HPMC) is a derivative of methylcellulose. HPMC is a non-ionic cellulose ether made from natural renewable polymers, such as cotton or wood pulp. It is an odorless, tasteless, non-toxic white powder, which can form a transparent viscous solution when dissolved in cold water.


Hebei yicheng produces and provides different types of HPMC for different application fields.

HPMC's improvement effect on cement-based materials

Hydroxypropyl methylcellulose (HPMC for short) has excellent thickening properties and can be used as a good anti-dispersant for concrete. In recent years, with the development of exterior insulation technology, the improvement of the cellulose production process and its own excellent performance, hydroxypropyl methylcellulose has been widely used in the construction industry.

Dispersion resistance is an important technical index to measure the quality of dispersant resistance. Hydroxypropyl methylcellulose is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer, is a hydrophilic polymer material that increases the consistency of its mixture by increasing the viscosity of mixing with water, and can be dissolved in water to form a solution or dispersion. As the amount of hydroxypropyl methylcellulose increases, the dispersion resistance of fresh cement mortar will become better and better.


Advantages of HPMC used as cement

(1). The addition of hydroxypropyl methylcellulose has a significant retarding effect on the mortar mixture. As the amount of hydroxypropyl methylcellulose increases, the setting time of the mortar will be gradually extended. In the case of the same amount of hydroxypropyl methylcellulose, the setting time of underwater-formed mortar is longer than that of air-formed mortar. This characteristic is beneficial to underwater concrete pumping.

(2). The fresh concrete mortar with the addition of hydroxypropyl methylcellulose has very good bonding properties and almost no water secretion.

(3). The amount of hydroxypropyl methylcellulose and the water requirement of mortar showed a trend of first decreasing and then significantly increasing.

(4). Adding water reducing agent helps to improve the problem of increasing the water demand of mortar, but remember to reasonably control the amount of its addition; otherwise, sometimes the water resistance dispersibility of fresh cement mortar will be reduced.

(5). The structural differences between cement mortar specimens with hydroxypropyl methylcellulose and blank specimens were not significant; moreover, the cement mortar specimens cast in water and air did not differ much in structure and density. The main reason is that although the addition of hydroxypropyl methylcellulose greatly reduces the loss and dispersion of cement cast in water, it also makes the density of cement lower. In construction, the amount of hydroxypropyl methylcellulose should be reduced as much as possible under the condition of ensuring the effect of underwater non-dispersion.
