Hydroxypropyl Methylcellulose (HPMC) is a versatile additive used in gypsum-based products to improve workability, water retention, and adhesion. Shijiazhuang Xinhong Chemical Co., Ltd. specializes in producing high-quality HPMC, tailored to meet the needs of the construction industry, particularly in gypsum applications.
Improved Workability: HPMC enhances the spreadability and ease of application of gypsum mixtures, resulting in smoother finishes.
Water Retention: The water retention properties of HPMC ensure a longer open time for gypsum mixtures, preventing premature drying and improving curing efficiency.
Adhesion Improvement: HPMC increases the bond strength between gypsum and various substrates, resulting in durable applications.
Sag Resistance: Helps prevent sagging during application on vertical surfaces, leading to more even finishes.
Improved Open Time: Extended working time gives users the flexibility to adjust or perfect their application without the material setting too quickly.
Our HPMC is available in 25 kg multi-layer paper bags with inner polyethylene liners to ensure product integrity during storage and transportation.

The dosage of HPMC typically ranges from 0.1% to 0.5% of the total gypsum mix, depending on the specific application and desired performance. It is essential to test different concentrations to find the optimal dosage that balances workability, water retention, and drying time for the specific gypsum product.
The viscosity of HPMC plays a crucial role in determining the flow and workability of gypsum products. Higher viscosity HPMC provides better water retention and thickening properties, making it suitable for applications like plasters and joint fillers. Lower viscosity grades are ideal for self-leveling compounds, where smooth flow and spreading are essential.
HPMC typically has a shelf life of 2 years when stored in a cool, dry place. It should be kept away from moisture and extreme heat to maintain its effectiveness. Proper storage ensures that the product retains its performance characteristics, such as water retention and viscosity, throughout its shelf life.
Yes, HPMC formulations can be customized based on specific requirements of gypsum-based products, such as plasters, joint fillers, or self-leveling compounds. Viscosity, water retention, and setting time can be adjusted to fit the exact needs of the application, ensuring optimal performance.
HPMC controls water retention, which can delay the drying time, giving users more time to work with the gypsum product before it sets. This extended "open time" is beneficial for achieving precise finishes and adjustments during application. However, it ensures that drying occurs evenly, reducing the likelihood of surface cracks or deformities.
