One of the primary drivers for the increase in demand for RDP is the growth of the construction industry, especially in emerging economies. Rapid urbanization and infrastructure development, particularly in Asia-Pacific and Latin America, are fueling the need for advanced building materials. Countries like China and India are experiencing a construction boom, with investments in residential, commercial, and infrastructure projects. This surge in construction activity directly correlates with the expanding market for redispersible polymer powders, as these materials play a crucial role in enhancing the performance of construction applications.
China has witnessed remarkable growth in its pharmaceutical industry over the past few decades. As the country has increasingly focused on innovation and modernization in pharmaceuticals, the demand for high-quality excipients has surged. This is where HPMC comes into play. The polymer is particularly valued in the production of controlled-release drug formulations. Its ability to form a gel in the presence of water allows for the gradual release of active ingredients, thereby improving therapeutic efficacy and patient compliance.
2. Concentration The concentration of HPMC in solution directly affects viscosity. As the concentration increases, the viscosity of the solution rises exponentially. This phenomenon is attributed to the increased number of polymer chains in the solution, leading to higher friction and resistance to flow.
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.
1. Construction In the construction industry, dispersible polymer powders are commonly used as additives in cement-based materials. They enhance properties such as workability, adhesion, and water retention, contributing to the overall performance of concrete and mortars.
In the food industry, hydroxyethyl cellulose serves as a food additive that acts as a thickener and stabilizer, ensuring the desired consistency and texture of various food products. It is commonly used in sauces, dressings, and dairy products, where it helps improve mouthfeel and stability. Furthermore, HEC is recognized for its ability to form gels, making it a popular choice in low-fat and reduced-calorie food formulations.
