HPMC Polymer Uses

Hydroxypropyl methylcellulose (HPMC), also known as hydroxypropyl methylcellulose ether, is a nonionic cellulose derivative. It appears as a white or off-white powder and is soluble in water and some organic solvents. Its aqueous solution exhibits high transparency and surface activity, with its gelation temperature varying depending on the methoxy group content. HPMC is a core dispersant in the suspension polymerization production of polyvinyl chloride (PVC). It reduces the interfacial tension between the monomer and water and modulates the resin particle morphology to improve processing performance. It can replace traditional dispersants and form composite systems with polyvinyl alcohol. HPMC is also used in the building materials industry as a water-retaining agent for cement mortars and tile adhesives, as a thickener and stabilizer in the coatings industry, and in the pharmaceutical industry for tablet coatings and sustained-release formulations. Its technical specifications include a methoxy group content of 28-30%, a hydroxypropoxy group content of 7-10%, and a solution viscosity range of 3-50 mPa·s, meeting the needs of various industries, including building materials, chemicals, and daily chemicals.

Description

Products Description

In recent years, Hydroxypropyl Methylcellulose (HPMC) has gained significant attention in various industries due to its versatile properties and wide range of applications.
HPMC is a non-ionic cellulose ether that is commonly used as a thickening agent, stabilizer, and emulsifier in the food industry. It is also utilized in pharmaceuticals as a binder, film-former, and controlled release agent in tablets and capsules. Moreover, HPMC is found in personal care products such as lotions, creams, and shampoos, where it acts as a viscosity modifier and film-forming agent.
One of the key reasons for the growing popularity of HPMC is its ability to improve the texture, stability, and shelf life of products. In the food industry, HPMC is often used to enhance the mouthfeel and appearance of various products, such as sauces, dressings, and baked goods. In the pharmaceutical industry, HPMC is valued for its role in ensuring the uniform distribution of active ingredients in tablets and capsules, as well as its ability to control the release of these ingredients in the body.

Products usage

In the food and pharmaceutical industries, it is used as an additive. Due to its adhesive and film-forming properties, its ability to thicken and disperse liquids, prevent oil penetration, and retain moisture, it is used as an adhesive, thickener, dispersant, reliever, stabilizer, and emulsifier. It is non-toxic, has no nutritional value, and does not undergo metabolic changes.

In addition, HPMC is used in synthetic resin polymerization, petrochemical industry, ceramics, papermaking, leather, cosmetics, coatings, building materials and photosensitive printing plates.
