November 22nd 2024
Hydroxypropyl methylcellulose (HPMC) is a non-ionic water-soluble cellulose ether that is used as a thickener, water retention agent, and suspending agent in a variety of applications, including gypsum plaster. HPMC is a white or off-white, odorless, and tasteless powder that is soluble in water and most organic solvents. It is available in a variety of grades, each with its own unique properties. HPMC is a versatile material that can be used in a wide range of applications, and it is an important ingredient in many industrial and consumer products.
HPMC is used in gypsum plaster to improve its workability and performance. It helps to thicken the plaster, which makes it easier to apply and prevents it from sagging. HPMC also helps to retain water in the plaster, which prevents it from drying out too quickly and cracking. This makes for a smoother, harder, and more durable finish.
The price of HPMC varies depending on the grade, quantity, and supplier. However, as a general rule, HPMC is a relatively inexpensive material. For example, a 25 kg bag of HPMC can be purchased for around $25-$35 USD.
