产品详情
Properties:
Easy to dissolve in water and most organic solvents, it can still form clear and transparent solutions even at high concentrations. The aqueous solution is non-ionic and does not require neutralization. It can be compatible with most inorganic salts, resins, and most excipients.
Specification：
Name | Status | Molecular Weight Mw | K value | Application |
KoVidone® K12 | Powder | 3,000 - 7,000 | 10.2 - 13.8 | pore forming agent and modifier. |
KoVidone® K15 | Powder | 8,000 - 12,000 | 12.75 - 17.25 | |
KoVidone®K17 | Powder | 10,000 - 16,000 | 15.3 - 18.36 | |
KoVidone® K25 | Powder | 30,000 - 40,000 | 22.5 - 27.0 | pore forming agent and modifier. |
KoVidone® K30 | Powder | 45,000 - 58,000 | 27 - 32.4 |
Note: 1) The K value is obtained by converting the kinematic viscosity of a 1% aqueous solution and calculating the viscosity average molecular weight according to the Mark Houwink formula.
Main applications:
1. Nylon material casing modifier, improves film-forming breathability, used for making smoked casings.
2. Can be melted and extruded with various casing resins to improve the properties of casing materials.
