Properties and Applications of HPMC Methyl Cellulose in Various Industries
Viscosity
Daily chemical grade instant hydroxypropyl methyl cellulose is usually used in daily chemical washing products, such as hand sanitizer, laundry detergent, car wash liquid, etc.
The properties of daily chemical grade hydroxypropyl cellulose A mainly include:
1. Water solubility and thickening property: it can be rapidly dissolved in cold water, without agglomeration, and can be dissolved in some organic solvents and the mixture of water and organic solvent. It can be dissolved in alcohol water solution and used to make disinfectant hand sanitizer.
2. Thickening and viscosity increasing performance: a small amount of solution will form a transparent viscous solution with high transparency. The transparency of 1% aqueous solution is more than 90%. The performance is relatively stable. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility. It can effectively improve the flow stability of the system.
3. High thickening effect: the viscosity of 1% aqueous solution is 200000mps, which can achieve the same thickening effect with less addition.
4. It can be operated for a long time: Hydroxypropyl cellulose A is rapidly dissolved in aqueous solution, and thickens after about three minutes. The operation time is sufficient, and at the same time, problems such as agglomeration and uneven mixing are avoided.
MHEC also finds use in cement-based mortars and renders. When added to these mixtures, it improves the adhesion properties, allowing for better bonding to various substrates. This is particularly important in applications such as plastering and rendering, where a strong bond between the substrate and the cement is essential for long-term durability.
