Properties--H-HPC
 

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 acetone, chloroform and 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.

 

Properties--L-HPC

1. L-HPC is mainly for application of chemicals as adhesive agent and crack agent forming agent to improve hardness crack ability increasing freedom of release as well as improve inner quality and curative effect. Especially for some big fragile tablets with high elasticity, L-HPC can improve the hardness and finishes as well as make the tablets swiftly crack. Even if the hardness is 13kg, crack only need about 10 minutes.
2. Add 5-20% percent when make tablets adhesives using wet method. Direct usage can be 5-20%   when directly form tablets, when used as tablet crack agent, it shall be 2-10% dosage. Normally, use 5% both inside and outside according to certain prescription.
3. L-HPC is also used as additives for foodstuff as emulsification, stabilizing agent, suspending agent, thicker agent, coating agent for drinks, cakes ,jams, etc.
   4.L-HPC is also used in daily chemicals when making frost agent, shampoo, emulsion, etc.
