HPMC powder building grade

The HPMC powder building grade produced by Milestone is produced with high-quality cotton fiber, which guarantees the high quality of the product from the beginning of the raw material. A unique process is used in the subsequent processing, and samples will be retained for testing after each batch of production is completed to ensure that the product quality is qualified.

Below we will introduce a few simple and direct methods, so that everyone can easily distinguish when buying.

v Whiteness: Although the whiteness cannot determine whether HPMC powder building grade is easy to use, and if some factories add whitener during the production process, it will also affect its quality. However, most good products have good whiteness.

v Fineness: The fineness of HPMC is generally 80 mesh and 100 mesh, and 120 mesh is less. Most of the HPMC powder building grade produced by Milestones is 80-100 mesh. The finer the fineness, the better the quality in general.

v Transmittance: After putting HPMC powder building grade in water to form a transparent colloid, look at its transmittance. The greater the transmittance, the better, indicating that there are less insolubles. The permeability of the vertical reactor is generally good, and the horizontal reactor is worse, but it does not mean that the quality of the vertical reactor is better than that of the horizontal reactor. The product quality is still determined by many factors.

v Proportion: The larger the proportion of HPMC powder building grade, the heavier the better. The high specificity is generally due to the high hydroxypropyl content in it, and the higher the hydroxypropyl content, the better the water retention.
