Product Specification/Models
1.appearance: white or off-white powder
2.granularity:passing rate of 100 meshes: >= 98.5%; passing rate of 80 meshes:100%. Particle size of special model: 40-60 meshes
3.carbonization temperature:280-300 centigrade
4.apparent density:0.25-0.70g/cm(0.5g/cm around as usual), specific gravity:1.26-1.31
5.thermochromic temperature:190-200 centigrade
6.surface tension:2%, aqueous solution:42-56dyn/cm
7.solubility: it is dissolved in water or some solvent, such as well-proportioned alcohol/water, propanol/water etc. The aqueous solution is surface activity, high transparent and stable. Different models have different gelation temperature. And the solubility is changing according to viscosity. Different specifications of HPMC have different property. HPMC which dissolves in the water is not influenced by PH.
8.HPMC rises the gel point, lowers the water solubility and surface activity when the methoxy decreases.
9.HMMC also has thickening, salt resistance, low ash, stable size, forming ability, enzymes resistance, dispersity and caking property.
