HPMC for Gypsum

Product Description

In gypsum products, cellulose ethers are mainly used to retain water and increase smoothness. Together they provide some relief. It can solve the doubts of drum cracking and initial strength during construction and prolong working time.

We have specially developed gypsum grade HPMC to improve processability, water retention, consistency, stability and sag resistance and adhesion to different substrates.

Products Description:

HPMC It's a kind of chemical materials, white or slight off-white granular powder, ororless. HPMC is a natural polymer materials as a raw materials, through a series of chemical processing and prepared non-ionic cellulose. 

What is HPMC for gypsum?

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained from cellulose after alkalinization, etherification, neutralization and washing.

HPMC for gypsum has good thickening, dispersing, emulsifying and film-forming properties, and is the first choice for producing high quality building material additives.

Properties of HPMC for gypsum

To meet the needs of environmental protection, our product has the characteristics of high water retention, good dispersibility, good fineness, good processability and easy dissolution. It is widely used in building substrates, with good water retention and improved workability. It can also prolong the opening time and improve the anti-sagging property.

Role of HPMC in gypsum products

Anti-shrinkage, anti-hollowing and anti-cracking properties

Good anti-sagging property

Good workability

Good water retention

Environmental protection

Water retention

HPMC is an efficient insurance agent, has a wide range of applications in ceramics, building materials and many other aspects.


HPMC as a high-performance adhesive, applied paint, paper, tobacco products and ceramic products.


Because of its thickening effect, they are able to prevent the construction materials to be bonded mortar and slip ang broken phenomenon appears.

HPMC Features

Recommended reading: HPMC's effect on gypsum products 

With the rapid development of construction industry, people's demand for new construction materials is increasing. Due to the increase of people's awareness of environmental protection and the continuous improvement of construction efficiency, gelling materials and gypsum products have been developed rapidly. Nowadays, the most common gypsum products are gypsum plaster, self-adhesive plaster, pre-built gypsum and tile adhesive. 

Gypsum plaster is a high-quality plastering material for interior walls and ceilings. After use, the wiped wall surface is smooth and delicate, without powder, firmly bonded with the substrate, without cracking and falling off. And it has fireproof function. 

Mastic is a new type of building light board adhesive, which is a sticky material made of gypsum as the substrate and adding many kinds of additives. It is suitable for bonding between all kinds of inorganic building wall materials. It is non-toxic, tasteless and has the characteristics of early, strong, fast curing and firm bonding, which can be used as a support material for building panels and buildings.

These gypsum products have a range of different functions. Gypsum and associated fillers play a role. In addition, the key issue is that the addition of cellulose ether additives plays a dominant role. Since gypsum can be divided into hard gypsum and hemihydrate gypsum, different types of gypsum have different effects on the performance of the products, so the properties such as thickening, water retention and retarding determine the quality of gypsum building materials.

The common problem of these materials is hollow cracks and failure to reach the initial strength. To solve this problem, there is an option to use a compound of cellulose model and retarder. For this, hydroxypropyl methyl cellulose 30,000-60,000 cps is generally used, with an addition of 1.5%-2%. Among them, cellulose plays the main role of water retention, retardation and lubrication. However, in this process, cellulose ether alone as a retarder does not achieve the effect, mixed with citric acid retarder will not affect the initial strength.
