Hydroxypropyl Methyl Cellulose (HPMC)-Shijiazhuang Gaocheng District Yongfeng Cellulose Co., Ltd.|Tile Adhesive Enhancer&Plaster Additive Solution

Hydroxypropyl Methyl Cellulose (HPMC) is a versatile chemical additive widely used in the construction industry. As a derivative of cellulose, it offers exceptional performance in applications such as tile adhesives, cement mortars, and gypsum-based products. This article provides an in-depth analysis of its technical specifications, functional advantages, application scenarios, and the company background behind this innovative material.

Product Overview

HPMC is a white or milky white powder with a carbonization temperature ranging from 280–300°C and a color temperature of 190–200°C. Its particle size is highly refined, with 98.8% passing through 100 mesh and 99.9% through 80 mesh. Special specifications may include 40–60 mesh particles. The apparent density is 0.25–0.70 g/cm³, while its specific gravity falls between 1.26–1.31. HPMC is soluble in water and certain solvents, such as ethanol/water or propanol/water mixtures, forming transparent, stable aqueous solutions with surface activity. These properties make it a critical component in construction materials.

Key Functional Advantages

HPMC is prized for its thickening ability, salt resistance, low ash content, pH stability, water retention, dimensional stability, film-forming properties, and mildew resistance. These characteristics enhance the workability, adhesion, and durability of construction materials. For instance, in cement mortars, HPMC improves fluidity and water retention, ensuring even application and reducing cracking. In ceramic tile cement, it acts as a suspension agent and adhesion enhancer, preventing slippage during installation.

According to NIST (National Institute of Standards and Technology), cellulose ethers like HPMC are critical for optimizing the rheological properties of cementitious systems. Their high water retention ensures consistent hydration of cement, while their film-forming ability creates a protective barrier against moisture loss (NIST, 2023).
