3. Physical Properties:
(1) Out looking:HEMC is a white or light gray pellet or fibril power with odorless and tasteless.
(2) Solubility:type of ¡°H ¡° can d issolve in other coll or hot water,¡±L¡± can only dissolove in cold water,hardly dissolve in all arganic solvents.
(3) PH stable:viscosity change is small when PH is within 2-12 but decrease when PH low than the range.
(4) Pellet:40 screen pass rate: ¡Ý 99%
(5) Density:0.30~0.60g/cm3
(6) Thicker agent, suspending agent, adhesive agent, emulsification agent, coating agent, water keeping agent and protective agent,etc. Whater keeping ability is better MC. It is stable in viscosity and anti-mildew and dispersant is stronger HEC.
4. Application:
HEMC is mainly used as adhesive protective gelatin, thicker agent and stabilizing agent as well as additives to make emulsion, frozen gelatin, lotion, eye clear agent, suppository and tablets.
5. Packing, transport and storage:
In 25kg net kraft paper bag, 12MTs/20¡¯FCL, 10MTs /20¡¯FCL if palletized.
Keep dry where good ventilated. Do not wet, and keep from sunshine when transport. |
