Product Description
High Substitution Hydroxypropyl cellulose(H-HPC)
Product Characteristics
1. Out looking: H-HPC is a white or lightly white powder, odorless and tasteless.
2. Pellet: 20 screen passable rate is over 99%, 30 screen passable rate is 95%.
3. Fault sepcific gravity:0.50-0.60g/cm3 ,gravity: 1.2224g/cm3
4. Thermo stability:
Temperature at which color change: 195~210C.
Carbonization temperature:260~275C.
Intenerate point:130C.
At temperature low than 38C, becomes clear and transparent solution in water. Gelatin temperature: over 40C.
Properties
1. At normal temperature, it can dissolve it in many kinds of liquids such as absolute ethyl carbinol, alcohol, isopropyl, dichloride-methane, as well as in acid solution agent. All solution are clear and transparent.
2. H-HPC is good thermoplastic material with excellent film forming ability. Film formed using H-HPC is very rigid with good polish and high elasticity.
3. Low content of ash presents result excellent adhesive. It can be used as adhesive agent for latex, stable with good dispersing ability.
4. H-HPC is not a drug itself, poison less and has no physiological effect.
5. H-HPC possesses good chemical inertia, hardly to react with other chemicals.
6. The substitute base is distributed uniformly and sufficiently thus H-HPC is powerful in antibacterial.
7. Low content of balance moisture.
8. H-HPC does not become gelatin in acid solution due to its non-ionic composition and in large range of PH solution, its presents excellent stability.
9. Solution of H-HPC can form regular liquid crystal of tropism.
10. Solution of H-HPC possesses surface activity.
11. With temperature rising and down, solution of H-HPC can change from gelatin to solution which is.
