Hidroxipropil Metil Zelulosa HPMCren zehaztapenak

Hidroxipropil metil zelulosa (HPMC) Baldintzak

Itxura eta mota fisikoa

HPMC appears as a white or somewhat off-white, hauts askea. It has no noticeable odor and feels smooth to the touch. The powder does not clump under normal storage space problems.

Disolbagarritasuna

HPMC liquifies easily in chilly water to create a clear, soluzio lodia. Ez da ur beroan disolbatzen, alkohola, or most organic solvents. When mixed with cool water, it swells initially and afterwards gradually liquifies without developing swellings if effectively spread.

Biskositatea

Thickness varies based on grade. Usual viscosity arrays include 5 mPa · s to 100,000 mPa · s at a 2% focus and 20 °C. Each set is tested to guarantee it meets the stated thickness variety. Higher viscosity qualities give thicker remedies and far better film-forming capability.

Alternative Levels

HPMC contains 2 crucial substituents: methoxy and hydroxypropoxy groups. Common methoxy web content ranges from 19% to 30%. Hydroxypropoxy content generally falls in between 4% eta 12%. These worths figure out how the item behaves in various applications.

pH merezi du

A 2% liquid solution of HPMC has a pH in between 5.0 eta 8.0. This neutral-to-slightly-alkaline variety makes it suitable with many other active ingredients made use of in building, farmazia, eta janaria.

Hezetasun edukia

The dampness degree in HPMC is maintained below 5% pisuaren arabera. Low dampness makes sure good flowability and long service life when stored in a completely dry area.

Errauts Edukia

After incineration, the residue (lizarra) stays listed below 5%. This suggests high pureness and marginal not natural impurities.

Zatiaren Dimentsioa

Most HPMC powders travel through a 40-mesh filter. Great grades might go through an 80-mesh or 100-mesh screen for smoother dispersion in sensitive applications.

Gogoan izan: All specs undergo variant based on production standards and customer requirements. Constantly describe the certification of analysis for the specific batch being used.
