- One of the primary uses of HPMC is as a binder in tablet formulations.
- The global redispersible polymer powder market is highly competitive, with major players including Wacker Chemie AG, Basf SE, Dow Chemical Company, and AkzoNobel N
- In the pharmaceutical industry, HPMC is used as a binder, disintegrant, and film-forming agent in tablets and capsules. It helps to hold the tablet together and ensure that it disintegrates properly in the body. HPMC is also used in the production of controlled-release formulations, where it helps to regulate the release of medication over a period of time.
- Chemically, HPMC is produced by treating cellulose with an alkaline solution followed by reacting it with methyl chloride and propylene oxide. The resulting compound is a white or off-white granular solid, which is odorless and tasteless. It's this substance that acts as a powerful tool in the hands of manufacturers across various sectors.

3)Temperature variations significantly affect the water retention of Methyl Cellulose. Generally, higher temperatures result in poorer water retention. If the temperature of the mortar exceeds 40℃, the water retention of Methyl Cellulose deteriorates, adversely affecting the workability of the mortar.
- Vinyl acetate ethylene redispersible powder is a versatile and essential material used in a wide variety of applications in industries such as construction, textiles, adhesives, and coatings. This unique powder consists of a mixture of vinyl acetate and ethylene copolymers, along with various additives such as protective colloids, stabilizers, and redispersible polymer powders.
Wofür wird HPMC außerdem verwendet?
Hydroxypropyl Methylcellulose (HPMC) plays a crucial role in pharmaceutical formulations due to its diverse range of benefits. One of its primary uses is as a key component in controlled-release drug delivery systems. HPMC’s ability to modify drug release rates enables pharmaceutical companies to develop medications that provide sustained therapeutic effects, leading to improved patient compliance and reduced dosing frequency. Moreover, HPMC is utilized as a binder in tablet formulations, contributing to the mechanical strength and disintegration properties of tablets, thereby ensuring consistent drug release and bioavailability. Its biocompatibility and inert nature make it suitable for a wide range of drug formulations, including oral, topical, and ophthalmic products, underscoring its versatility in pharmaceutical applications.

Cellulose is a linear homopolymer consisting of repeating β-d-glucopyranosyl units linked via (1,4) glycosidic bonds. In its pure form, the straight chains are bound closely together by multiple intermolecular hydrogen bonds and van der Waals forces, producing a water-insoluble fibrous or crystalline substance which is relatively inert. The EFSA ANS Panel assessed recently the absorption, distribution, metabolism and excretion (ADME) of celluloses (EFSA, 2018) and draw the following conclusions concerning non-herbivore mammals: cellulose is not absorbed intact in the gastrointestinal tract of animals and humans but is fermented during its passage through the large intestine by the microbiota, with the limited production (9% of the administered dose in the rat) of short-chain fatty acids (mainly acetic acid and succinic acid), hydrogen, carbon dioxide and methane.
