what is hpmc ?
Chemical Name: Hydroxy Propyl Methyl Cellulose
CAS NO.: 9004-65-3 Abbreviation: HPMC MHPC
Industries: Construction, Coating, Paints, Detergent
HPMC is one of cellulose ethers, is short for hydroxypropyl methyl cellulose. It is also called hypromellose,or 2-hydroxypropyl methyl cellulose.
Material: High purlty Refined cotton
HPMC is a type of non-ionic cellulose ether, white powder appearance, odorless and tasteless, soluble in water and most polar organic solvents. Its water solution has a surface activity, high transparency, stable performance. HPMC has a thermal gel properties, after heating, the product solution formed the gel precipitation, dissolving after cooling. Different specifications products have different gel temperature. Solubility changes with viscosity's difference. The lower viscosity, the higher solubility, different specifications HPMC have difference in properties, dissolving HPMC in water won't be affected by PH value.
Granularity: 100mesh, over 99% passing rate, Bulk Density: 0.25-0.70g(usu. 0.5g or so), Proportion: 1.26-1.31, Color Temperature: 190-200℃
Carbonization Temperature: 280-300℃,Surface Tension: 42-56dyn/cm
With the increase of Methoxyl, HPMC's gel point decreases, the rise of water solubility and surface activity. HPMC has the features of thickening, salt removing, low ash content, fine film-forming properties. and wide range of anti-ether, dispersion, and adhesion properties.
Properties:
1.Enhances water retention--improved water retenion can protectcement and plaster against poor solidification and cracking due to speedy drying and inefficient mixing with water.
2.Workablilty--mortar plasticizing quality can be improved, which in turn will improved the workability of painting and working efficiency.
3.Binding--Due to increased plasticizing quality, mortar can be a better binde.
4.Slipping resistance--Due to the thickening action of Cellulose Ether,the slipping phenomena of mortar from substance to be bound can be prevented more efficiently.
