HPMC Polymer

HPMC stands for hydroxypropyl methylcellulose, also known as hydroxypropyl methylcellulose. It is a semi-synthetic, neutral, viscoelastic polymer.HPMC is a water-soluble, biodegradable, biocompatible polymer with a wide range of applications such as pharmacology, coloring, cosmetics, adhesives, coatings, agriculture and textiles.

Physical and Chemical Properties

HPMC is a solid substance with the appearance of a white to cream-colored powder that can also be granular. The compound forms a colloid when dissolved in water. It is non-toxic, flammable and can react strongly with oxidizing agents. Hydroxypropylmethylcellulose in aqueous solutions, such as methylcellulose, exhibits thermal gelling. This means that when the solution is heated to a critical temperature, it turns into an immobile but elastic substance. These properties are very similar to those of methoxy concentrations;

Hydroxypropyl Methyl Cellulose Production Process

It is a semi-synthetic compound. Semi-synthetic means that the resulting compound is extracted and purified from a natural source. Culturing and extracting material from plants in a laboratory setting can produce semi-synthetic compounds, such as cellulose derivatives, which can be used as raw materials for the preparation of other similar compounds. These compounds, like the HPMC polymer compounds, are large molecules with an almost complex molecular structure. The compounds are produced by purifying fibrous plant material with sodium hydroxide, methyl chloride and propylene oxide.

Hydroxypropyl Methyl Cellulose Uses

In tile adhesive industry: the material is used in construction materials such as tile adhesive, as a rheology modifier and water retention material.
In paint and coating industry: It is used as thickener, dispersant and stabilizer in coating industry, with good solubility in water or organic solvents, also known as paint cleaner.
Production of gypsum products.
Use as a creator of geological properties and as a water retention material in construction materials.
Used in the plastics industry as a reducing, softening and lubricating agent.
Used as a dispersant in the production of PVC.
