Whiteness of HPMC: Although whiteness can not determine whether HPMC is easy to use, and if whitening agent is added in the production process, its quality will be affected. However, most good products have good whiteness.

HPMC is an important additive in mortar because of its excellent performance, which can improve the construction performance, pumping and spraying performance of mortar. The main performance is as follows.

The instant hydroxypropyl methylcellulose ether is designed for water agent products. The surface of hydroxypropyl methylcellulose ether is treated with Glyoxal at a certain temperature and pH value.

The HPMC Industrial Grades produced by Milestone Industrial Co. LTD. has thickening, adhesion, dispersion, emulsification, film-forming, suspension, adsorption, gel, surface activity, moisture retention and protective colloid properties.

Hydroxyl methyl cell chemical produced by milestone Industrial Co. Ltd. has been widely used in the construction industry：

The main indexes of industrial construction grade HPMC powder are hydroxypropyl content and viscosity. Hydroxypropyl content is high, water retention is generally better. Viscosity, water retention, relative (rather than absolute) is also better, and viscosity, in cement mortar better.
