Physicochemical Properties：
1.Exterior: White or off-white powder
2. Particle size: the passing rate of 80 mesh is 100%;the passing rate of 100 mesh is more than 99.5%.
3.Charring temperature:280-300°C.
4.Apparent density:0.25-0.70g/cm³(usually around 0.5g/cm³ ),the proportion is 1.26-1.31.
5.Thermochromic temperature:190-200°C.
6.Surface tension:2% of aqueous solution is 42-56dyn/cn.
7.Solubility:soluble in water and some organic solvents,such as ethanol &water in appropriate proportion,dioxo-ethane etc.Aqueous solution is surface-active,transparent with stable property.Products with different specifications gel at different tempera-tures and their solubility changes with viscosity:the lower the viscosity,the greater the solubility is.HPMCs with different specifica-tions have different properties.The solution of HPMC in water is not affected by PH.
8.When methoxy content decreases,HPMC's gel point increases,its solubility in water and surface activity decrease.
9.HPMC also has the following characteristics:thickening,salt exclusion,low ash content,stability in pH and dimension,water retention,excellent film-forming property,as well as broad enzyme resistance,dispersity and cohesiveness.
Storage considerations
The product is recommended to follow the principle of first in, first out. It is recommended to store in the original packaging in a dry and clean environment and away from heat sources. This product is easy to absorb water, and its packaging bag uses specific materials to prevent water from entering, but if it is not stored in a dry environment, its own water content may increase.
Safety precautions
The product is not a dangerous chemical normal use is not toxic.The powder is environmentally friendly products inedible.Avoid contacting with eyes skin and clothing otherwise wash with plenty of water.
