As a leading provider of chemical solutions, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying high-quality raw materials that drive innovation in various industries. Among our key offerings, Hydroxypropyl Methyl Cellulose (HPMC) stands out as a versatile and indispensable additive, particularly within the booming construction sector. This white or whitish powder, also known by its chemical auxiliary classification, is derived from highly purified cotton cellulose, undergoing specialized etherification under alkaline conditions to yield a product with exceptional performance characteristics.

HPMC acts as a critical component in numerous building material formulations. Its primary functions include acting as a thickener, stabilizer, and, most importantly, a water-retaining agent. These properties are vital for improving the workability, adhesion, and overall quality of construction mixes such as mortars, putties, plasters, and tile adhesives. By enhancing water retention, HPMC helps to prevent premature drying, especially in cement- or gypsum-based systems. This extended open time allows for more efficient application and ensures proper hydration of the binder, leading to stronger, more durable final products.

The application of HPMC brings significant advantages to construction projects. In wall putty, for instance, HPMC maximizes water content in the slurry, improves workability, and provides anti-sagging properties, allowing for thicker coats without deformation. For tile adhesives, it prolongs the open time, improves adhesion to various substrates, and enhances sliding resistance, which is particularly beneficial for heavier tiles. In cement plasters and dry mix mortars, HPMC facilitates easy dry mix formulations due prevents lump formation when mixed with cold water. It ensures appropriate water content is maintained, guaranteeing longer concreting time and easier spreading with improved sagging resistance.

Beyond these specific examples, HPMC finds extensive use in exterior insulation and finish systems (EIFS), where it improves adhesion and wetting ability for EPS board and substrates, while also reducing air entrapment and water uptake. In self-leveling mortars, low viscosity grades help protect against water exudation and material sedimentation, improving surface finish performance. For crack fillers, HPMC provides proper thickness and plasticity for better workability and ensures prolonged working time through its water retention capabilities.

The properties of HPMC, such as its thickening ability, salt resistance, low ash content, pH stability, excellent film-forming capacity, and wide range of enzyme resistance, contribute to its widespread adoption. Different applications may require different viscosities, ranging from 200 to 200000 mPa.s, and NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of tailoring product specifications to meet specific customer needs. Our HPMC undergoes rigorous quality control, adhering to standards for methoxy content, hydroxypropyl content, viscosity, ash content, and water content.

HPMC is packaged in moisture-proof bags and should be stored in a cool, dry, and well-ventilated place to maintain its quality. Proper storage ensures the product remains ready for use, and any remaining material should be carefully sealed to prevent moisture absorption.
