Why choose YIDA Hydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methylcellulose can increase the viscosity of the mixed water and increase the consistency of the mixture. It is a hydrophilic polymer material that can be dissolved in water to form a solution or dispersion. High water retention can fully hydrate the cement, significantly increase the bonding strength, and at the same time, it can appropriately increase the tensile strength and shear strength, improve the construction effect, and improve the work efficiency. Therefore, it is widely used in dry mix mortar.

There are many HPMC suppliers all over the world, and most of them are distributors rather than manufacturers.
A truly professional HPMC manufacturer has a strict production process in addition to special equipment.
Hebei Yida's HPMC production process is as follows:
Hydroxypropyl methyl cellulose (HPMC) is made of refined cotton after being pulverized, alkalized with sodium hydroxide (liquid caustic soda) solution, and then added with chloromethane + propylene oxide for etherification reaction to form HPMC crude product , After neutralization (pH value adjustment), filter press, drying, crushing and sieving, pure HPMC with a certain fineness can be obtained. The finished product has a slight smell, the smell of methane.
