HPMC YB 5100MS
EipponCell HPMC MP100MS is a hydroxypropyl methylcellulose used in daily chemical products. It is a white or slightly yellowish powder that has no odor, taste, or toxicity. It can easily dissolve in cold water and organic solvents, forming a clear and thick solution. When dissolved in water, it exhibits surface activity, high transparency, and strong stability, remaining unaffected by pH levels. In shampoos and shower gels, it acts as a thickening agent and provides antifreeze properties. It also possesses water retention capabilities and forms a good film on hair and skin. By utilizing cellulose (an antifreeze thickener) in shampoo and shower gel formulations, it significantly reduces costs while achieving the desired effects, especially in light of the recent increase in raw material prices.

HPMC YB 5150MS
EipponCellHPMC YB 5150MS is a type of Hydroxypropyl methylcellulose that demonstrates limited solubility in absolute ethanol, ether, and acetone. However, when exposed to hot water at temperatures ranging from 80 to 90°C, it disperses rapidly and undergoes swelling, ultimately dissolving quickly upon cooling. The aqueous solution of this compound exhibits remarkable stability at room temperature and is capable of forming gels when subjected to elevated temperatures. These gels exhibit temperature-dependent changes in consistency.
EipponCellHPMC YB 5150MS possesses a range of exceptional properties, including excellent wettability, dispersibility, adhesiveness, thickening, emulsification, water retention, and film-forming capabilities. Additionally, it exhibits impermeability to oil. Films formed from this compound demonstrate outstanding toughness, flexibility, and transparency. Being non-ionic in nature, it can easily coexist with other emulsifiers. However, it is susceptible to salt precipitation and maintains solution stability within the pH range of 2 to 12.

HPMC YB 5200MS
EipponCell HPMC YB 5200MS is a hydroxypropyl methylcellulose ether with the highest viscosity available for home care and personal care applications. With a viscosity of 200,000, it is specifically designed for use in daily chemical products. This HPMC variant can be easily dissolved in both hot and cold water, but it is generally insoluble in organic solvents. It exhibits excellent solubility and viscosity characteristics, remaining stable even at high temperatures or boiling. Additionally, it undergoes non-thermal gelation and has minimal post-thickening effects. The stability of HPMC in various conditions is remarkable.
When employing hydroxypropyl methylcellulose ether in the realm of daily chemicals, its exceptional properties make it a popular choice as a thickener, emulsifier, and binder in various everyday products. To utilize it effectively, HPMC is typically dissolved in a specific amount of water during the stirring process to create a clear and smooth mother liquor. It is important to avoid shoveling or dumping HC and maintain continuous stirring until the desired consistency is achieved. It is advisable not to introduce other substances during this process to prevent any impact on the system’s pH value. To enhance the product’s quality, increasing the temperature and pH value of the system is recommended.

HPMC E 50
EipponCellHPMC E 50 Hydroxypropyl methylcellulose is a prominent type of dispersant used in the polyvinyl chloride (PVC) industry. It is utilized during the suspension polymerization of vinyl chloride to effectively reduce the interfacial tension between vinyl chloride monomer (VCM) and water. This reduction in tension helps to uniformly and stably disperse the VCM within the water medium. Additionally, it aids in preventing the merging of VCM droplets at the onset of the polymerization process and inhibits coalescence between polymer particles in the intermediate and later stages. In the suspension polymerization system, EipponCellHPMC E 50 Hydroxypropyl methylcellulose serves a dual purpose of dispersion and stability protection.

HPMC F 50
EipponCellHPMC F 50, a hydroxypropyl methyl cellulose, functions as a dispersant in the PVC industry. In the suspension polymerization process of vinyl chloride, commonly used dispersants include polymer compounds such as polyvinyl alcohol and cellulose ether. When subjected to stirring, they facilitate the formation of droplets with suitable sizes. This capability is referred to as the dispersing ability of the dispersant. Additionally, the dispersant is adsorbed onto the surface of the vinyl chloride monomer droplets, forming a protective layer that prevents droplet aggregation and stabilizes them. This effect is known as the colloid retention ability of the dispersant.

HPMC YB 4000
EipponCellHPMC E4000 is a hydroxypropyl methyl cellulose ether specifically designed for use in ceramics. Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether derived from natural polymer material cellulose through a series of etherification processes. It is a white powder that is odorless, tasteless, and non-toxic. When added to cold water, it forms a clear or slightly cloudy colloidal solution. HPMC possesses several properties such as thickening, dispersing, emulsifying, film-forming, suspending, adsorbing, surface activity, moisture retention, and colloid protection. It finds extensive applications in various industries, including building materials, coating industry, synthetic resin, ceramic industry, textiles, agriculture, daily chemicals, and more.

HPMC YB 810M
EipponCell HPMC 810M is a ceramic-grade Hydroxypropyl Methylcellulose (HPMC), also known as Hypromellose and Cellulose Hydroxypropyl Methyl Ether. It is derived from highly pure cotton cellulose and undergoes a specific etherification process under alkaline conditions. HPMC exhibits thermal gelation properties. When its aqueous solution is heated, it forms a gel and precipitates, which can then be redissolved upon cooling. The gelation temperature varies depending on the specific product specifications. Solubility is influenced by viscosity, with lower viscosity resulting in greater solubility. The dissolution of HPMC in water is not affected by the pH value.
HPMC possesses several notable properties, including thickening ability, salt discharge, pH stability, water retention, dimensional stability, excellent film-forming capability, wide range of enzyme resistance, dispersibility, and cohesiveness. Each HPMC specification may exhibit slight variations in these properties.

HPMC YB 6000
EipponCellHPMC 6000 is a hydroxypropyl methyl cellulose ether specifically designed for ceramics applications. In a study, various proportions of powdered hydroxypropyl methyl cellulose (HPMC) and starch were utilized as binders in the extrusion process of silicon nitride green bodies. The investigation focused on evaluating the three-point bending strength of the samples and analyzing the microstructure of the fracture surface.
The results revealed that HPMC had a significant impact on enhancing the green strength compared to the use of starch. Incorporating 10% HPMC as a binder resulted in a flexural strength of 29.3±3.1 MPa, which was approximately 7.5 times higher than similar materials utilizing starch. The substantial increase in strength was attributed to the presence of coarse, fibrous HPMC particles that aligned themselves along the extrusion direction and exhibited pull-out behavior during the bending test.
