Hydroxypropyl Methyl Cellulose, commonly known as HPMC, stands as a cornerstone additive in the modern construction industry. As a leading cellulose ether, it is a non-ionic polymer derived from natural cellulose, processed to achieve unique properties essential for various building materials. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted provider of high-quality HPMC powder, offering this versatile material to enhance the performance and workability of construction applications worldwide.

Our HPMC is a white, odorless, and tasteless powder known for its excellent water solubility. Beyond simple dissolution, it imparts crucial functional benefits to mixtures, including thickening, adhesion, dispersing, emulsifying, film-forming, and water retention. These properties are vital for improving the efficiency and durability of construction products.

One of the most significant roles of HPMC in construction is its ability to control water migration. This water retention capability is paramount in cementitious and gypsum-based materials. By keeping water within the mix for longer periods, HPMC ensures that the hydration process of cement or gypsum is more complete, leading to improved strength development and reduced cracking. This is particularly important in dry-mix mortars, where rapid drying can compromise the final structure's integrity. The ability to maintain optimal moisture content also extends the open time of mortars and adhesives, giving workers more time to position materials correctly before the mix sets.

HPMC also acts as a highly effective thickener, modifying the rheology of wet mixes. This thickening action prevents sagging in vertical applications like wall plasters and tile adhesives, ensuring a consistent and even layer can be applied. It enhances the plasticity and workability of the mortar, making it easier to spread, trowel, and finish. Different viscosity grades of HPMC are available, allowing formulators to fine-tune the flow properties of their specific products, from self-leveling compounds requiring low viscosity to thick tile adhesives demanding high viscosity.

Furthermore, HPMC serves as an excellent binder and adhesive promoter. It helps to improve the cohesion within the mortar mix and significantly enhances the bond strength between the mortar and the substrate or tiles. This is achieved partly through its film-forming capability, creating a thin, flexible layer that aids in adhesion. The improved bonding is particularly beneficial in tile adhesives, especially for heavier tiles or challenging substrates, and in external insulation and finish systems (EIFS), where strong adhesion of insulation boards is critical for system longevity and performance.

Our high-quality HPMC finds extensive application across a wide spectrum of construction materials. It is indispensable in tile adhesives, tile grouts, skim coats, wall putty, coating and adhesive mortars for EIFS, crack fillers, decoration mortars, and various types of dry mixed mortars and cement plasters. For instance, in self-leveling applications, low-viscosity HPMC prevents material sedimentation and water exudation while its water retention ensures a smooth, high-quality surface finish. In cement plasters, it increases water demand, which can expand the application area and offer a more economical formulation while improving consistency and sag resistance.
