Hydroxypropyl Methyl Cellulose (HPMC)-Shijiazhuang Gaocheng District Yongfeng Cellulose|Tile Adhesive,Plaster Additives

Hydroxypropyl Methyl Cellulose (HPMC) is a chemically modified cellulose ether that has become a critical component in modern construction materials. As a key ingredient in tile adhesives and plaster additives, HPMC enhances the performance of cement-based products through its unique physical and chemical properties. This article provides an in-depth exploration of HPMC's technical specifications, applications, and the company behind its production, Shijiazhuang Gaocheng District Yongfeng Cellulose Co., Ltd..

Technical Specifications of HPMC

HPMC is a fine, white to off-white powder with exceptional solubility in water and certain organic solvents. Its technical parameters are meticulously designed to meet the demands of construction applications. Below is a detailed specification table:

Parameter	Specification
Appearance	Milky white or white powder
Carbonization Temperature	280-300°C
Color Temperature	190-200°C
Particle Size	100 mesh pass rate >98.8%; 80 mesh pass rate 99.9%
Apparent Density	0.25-0.70 g/cm³
Specific Gravity	1.26-1.31
Solubility	Soluble in water and solvents like ethanol/water or propanol/water mixtures

The high water retention and film-forming properties of HPMC make it an ideal additive for cement-based products. Its NIST-aligned specifications ensure consistency and reliability in construction applications.

Key Functional Advantages of HPMC

HPMC offers a range of benefits that enhance the performance of tile adhesives and plaster systems:

• Thickening Ability: Improves the viscosity of cement mortars, ensuring better workability.
• Salt Resistance: Maintains stability in environments with high salinity.
• PH Stability: Retains performance across a wide pH range.
• Water Retention: Prevents premature drying of cement pastes, enhancing adhesion.
• Dimensional Stability: Reduces shrinkage and cracking in dried products.
• Mildew Resistance: Inhibits microbial growth in moist conditions.

Applications in the Construction Industry

HPMC is widely used in various construction scenarios, including:

• Cement Mortar: Enhances cohesion and reduces water loss during curing.
• Ceramic Tile Cement: Improves adhesion and prevents tile slippage.
• Refractory Coatings: Acts as a suspension agent and improves substrate adhesion.
• Gypsum Coagulant Slurry: Boosts water retention and workability.
• Joint Cement: Enhances fluidity and adhesion in gypsum board joints.

The versatility of HPMC is evident in its ability to adapt to diverse construction needs. For example, in tile adhesive formulations, it ensures strong bonding between tiles and substrates while maintaining flexibility.
