By dealing with the source, you can ensure consistent quality, negotiate better pricing, and get technical support if needed. However, minimum order quantities may apply. 3.HPMC VS HEC : Solubility
- HPMC is a cellulose ether derived from natural cellulose. It is produced by treating cellulose with propylene oxide and methyl chloride to form a hydroxypropyl group and a methyl group, respectively. This modification of the cellulose structure imparts water solubility to HPMC, making it a valuable material for use in pharmaceuticals, construction, food, and cosmetics.
- Redispersible polymer powders, derived from the spray-drying process, are primarily used as binders in the production of dry-mix mortars. Their ability to enhance the properties like adhesion, flexibility, and water resistance of these mortars makes them indispensable in construction materials such as tile adhesives, plasters, and repair compounds. As the construction industry continues to boom globally, the demand for redispersible polymer powders is expected to rise proportionally.
- Hydroxypropyl methyl cellulose (HPMC) is a versatile polymer that is widely used in various industries due to its unique properties. HPMC is available in different grades, each tailored to specific applications. In this article, we will explore the different grades of HPMC and their uses.
- Hydroxypropyl methylcellulose (HPMC) is a versatile polymer that is used in a wide range of industries, including pharmaceuticals, food, and construction. HPMC comes in different grades, with varying degrees of viscosity, that are tailored to specific applications.

- The price of HPMC (Hydroxypropyl Methylcellulose) has been a subject of much debate and interest in the construction and pharmaceutical industries. This versatile polymer is used in a wide range of applications, including as a thickening agent, a binder, and a film-forming agent. As such, understanding the factors that influence its price is crucial for businesses that rely on this material.
- Dispersible polymer powders are essentially water-soluble polymers that have been processed into a dry, free-flowing form. They are derived from vinyl acetate-ethylene (VAE) copolymers, polyvinyl alcohol (PVA), or other similar polymers, which undergo a special spray-drying technique to achieve their powdered state. This transformation not only aids in easy storage and transportation but also enhances their usability in various applications where liquid forms may not be practical.
PH: both HPMC and HEC are stable to common acids and alkalis. Alkali can speed up its dissolution and slightly increase its viscosity. HPMC solution is stable in the range of ph = 2-12. caustic soda and lime water can not affect HPMC properties. Hydroxypropyl methylcellulose is stable to common salts. But when the concentration of salt solution is high, the viscosity of HPMC solution tends to increase.

What else can hydroxypropyl methylcellulose be called?
- Furthermore, the temperature also influences the thickening effect of HEC. At lower temperatures, HEC chains tend to be more rigid, enhancing the inter-chain interactions and viscosity. As the temperature increases, these interactions weaken, and the viscosity decreases – a phenomenon known as shear thinning. This temperature-dependent behavior makes HEC particularly useful in applications where viscosity control is crucial This temperature-dependent behavior makes HEC particularly useful in applications where viscosity control is crucial

Cellulose wird in heißer Natronlauge gequollen und bei 50 bis 80 °C mit Propylenoxid und hohem Methylchlorid-Druck umgesetzt; Letzteres reagiert erst bei hoher Temperatur. Typische Nebenprodukte von Polykondensationen und Hydrolyse des Propylenoxids sind Propylenglycol, Di- und Tripropylenglykol sowie neben Methanol auch deren Methylether (z. B. Methoxypropanol, Dipropylenglycolmonomethylether usw.). Zur Isolierung werden zuerst alle bis 110 °C flüchtigen Stoffe abdestilliert und anschließend mit heißem Wasser alle Glycole und Salze ausgewaschen, der Feststoff getrocknet und zum Pulver vermahlen. Für den Lebensmittel- und Pharmabereich ist die Herstellung unter GMP-Bedingungen vorgeschrieben.
