Hydroxypropyl Methylcellulose data data
Heino tafura inotsanangura imwe yakajairika tekinoroji data yehydroxypropyl methylcellulose (HPMC):
Property | Value |
---|---|
Chimiro chemakemikari | Cellulose derivative |
Molecular formula | (C6H7O2(OH)xm(OCH3)yn(OCH2CH3)z)n |
Molecular weight range | 10,000 - 1,500,000 g / mol |
Chitarisiko | Hupfu hwakachena kusvika kuchena |
Solubility | Soluble mumvura, insoluble mu organic solvents |
Viscosity range | 5 - 100,000 mPa · s (zvichienderana negiredhi reviscosity uye kutarisisa) |
Gelation tembiricha range | 50 - 90 ° C (zvichienderana negiredhi reviscosity uye kuisa pfungwa) |
