Hydroxypropyl methyl cellulose hpmc manufacturer
Hydroxypropyl methylcellulose (HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer materials as raw materials.
It contains almost all the properties of methyl cellulose (MC) and is your first choice for the production of quality building materials. In order to meet the needs of environmental protection, our factory specializes in the development and production of HD series products for the building materials industry. It has the characteristics of high water retention performance, good dispersibility, good fineness, good workability and convenient dissolution. It is suitable for dry mortar building materials, interior and exterior walls. Water-resistant putty powder (paste), binder, caulking agent, interface agent, water-based paint, self-leveling agent and other new building materials.
Product Features:
1.Appearance: HPMC is a white to light yellow powder or granular product
2.Solubility: HPMC is nearly insoluble in anhydrous ethanol, ethyl ether and acetone. It is swelled in cold water to form a transparent or a slight cloudy solution. HPMC can be dissolved into some organic solvents and also in water-organic solvent mixed solvents.
3.Graininess:The product particle size is greater than or equal to 80mesh.
4.With reduction of methoxyl groups content, HPMC is increased in gelling temperature and decreased in water solubility and surface activity.
Product properties:
1.Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2.Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3.Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4.Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
