HPMC viscosity refers to the thickness or flow resistance of its aqueous solution. It is commonly measured in millipascal-seconds (mPa.s) using a 2% solution with a Brookfield viscometer. HPMC is available in a wide viscosity range:
Low viscosity: 3 – 100 mPa.s
Medium viscosity: 100 – 40,000 mPa.s
High viscosity: 40,000 – 200,000+ mPa.s
The viscosity grade of HPMC affects several core functions:
Water retention
Adhesion
Thickening power
Film-forming ability
Workability and rheology
Selecting the right viscosity ensures optimal performance in your application.

Application
The most important property of hydroxyethyl cellulose powder is that it acts as a thickener, in creasing the viscosity of the liquid,and its thickening depends on its concentration. If you're searching for a versatile solution that enhances the performance of your products, look no further than Hydroxyethyl Cellulose (HEC) powder.
The gypsum special grade hydroxypropyl methyl cellulose HPMC has the characteristics of high water retention, dispersibility, good fineness, good workability and easy dissolution. widely used in gypsum products like gypsum plaster, adhesive plaster, embedded gypsum, tile adhesives etc.
Daily Chemical Products Additive
Daily Chemical HPMC has a variety of properties such as thickening, foam stabllization,emulifiation, and easy dispersion. Shampoo Additive HPMC has good compatibility with various additives of other daily chemical products. It is widely used in detergents, shower gels, shampoos, hand sanitizers, and laundry liquid and other products.
Tile Adhesive Additive HPMC can ensure the smooth construction on difterent base surtaces, even when the ambient temperalure is relalively harsh, the tile adhesive can be given a long enough open time and adjustable time.
In gypsum products, the focus is on water retention, retardation and lubrication. Different gypsum has different effects on product performance, so thickening, water retention, and retardation determine the quality of gypsum building materials.
Adding hydroxypropyl metylellulose can improve anti-sip performance, improve wetting performance, thicken, improve batch scraping and slipping, easy to level, improve surface performance and strength, and have very good compatibility with other additives.
Hydroxypropyl metylcellulose is a commonly used raw material in powdered building materials, which greatly improves the slip performance and anti-sag performance of the construction, improves the wettability, improves the anti-slip performance of the putty, improves the leveling effect of the putty, and improves the construction eficlency.
Technical Guidelines for Hydroxypropyl Methylcellulose (HPMC)
As a professional manufacturer of architectural-grade HPMC, we provide you with comprehensive technical guidance and problem-solving support throughout the production and application processes.
How much do you know about Hydroxypropyl methyl cellulose(HPMC)?
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained by cellulose alkalization, etherification, neutralization and washing. HPMC has good thickening, dispersing, emulsifying, film-forming properties, etc.It is the first choice for production of high quality building materials additives.
We have both Chemical Lab and Application Lab to ensure each order's best satisfaction
How to improve the adhesion of putty
When encountering the projects that have been constructed, it is found that the adhesion of putty on the exterior wall is poor, the following methods can be adopted to improve the adhesion of putty:
Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Goon stirring until it cools down and becomes clear
