Hydroxypropyl Methylcellulose (HPMC) is a versatile polymer derived from cellulose, which is a natural polymer present in the cell walls of plants. This modified cellulose has gained significant attention in various industries due to its unique properties and functionality. HPMC is primarily used as a thickening agent, emulsifier, and stabilizer, making it an essential ingredient in pharmaceuticals, food products, cosmetics, and construction materials.

China is one of the leading producers of HPMC, leveraging its extensive agricultural sector for the raw materials necessary for cellulose extraction. Major producers employ advanced manufacturing processes and technologies to ensure high purity and quality of the final product. The manufacturing hubs are primarily located in provinces such as Jiangsu and Shandong, where infrastructure and access to raw materials are optimal.

The backbone of hydroxyethyl cellulose consists of β-(1→4)-linked D-glucose units, akin to that of natural cellulose. The introduction of hydroxyethyl groups at the hydroxyl positions of glucose residues transforms its properties, making HEC soluble in water while maintaining its gel-forming abilities. This solubility is temperature-dependent, and the polymer’s behavior can vary significantly with changes in pH and ionic strength.

In conclusione, la polvere ridispersibile cinese sta diventando un elemento chiave nel panorama dell'edilizia moderna. Le sue proprietà uniche la rendono un alleato prezioso per migliorare la performance delle malte e garantire risultati duraturi. Con l'evoluzione del settore, è probabile che continuerà a guadagnare popolarità e ad aprire nuove opportunità per innovazioni nel campo delle costruzioni.

In order to improve the redispersibility of redispersible polymer powder and prevent caking during drying and storage, protective colloids or surfactants (emulsifiers) should be added before drying, making the redispersible polymer powder with strong hydrophilicity and alkali sensitivity. The most commonly used protective colloid is partially hydrolyzed polyvinyl alcohol (PVA). PVA contains a lot of hydroxyl groups, with quite poor water resistance. And the vinyl acetate polymer itself is poor in the water resistance, especially hot water resistance, due to its polar ester and carboxyl groups. In the redispersible polymer powder containing PVA and carboxyl groups, polyvalent metal salts can be added to improve its water resistance, especially hot water resistance, since PVA and carboxyl groups can react with metal salts to become insoluble in water. In the emulsion containing PVA, aldehydes can also be added for PVA acetalization and then to reduce its water absorption. In addition to PVA, some other protective colloids with good water resistance can also be selected to ensure the water resistance of product, such as polyacrylic acids and modified polyacrylic acids.

Chinese manufacturers have progressively adhered to international quality standards, such as ISO certification, to ensure that their products meet the requirements of global markets. The implementation of rigorous quality control measures throughout the manufacturing process ensures that HPMC products are of high purity and performance.
