FAQS on viscosity of hpmc

Q: What does viscosity mean for HPMC?

A: Viscosity refers to the thickness or flow resistance of Hydroxypropyl Methylcellulose (HPMC) solutions. It is measured in mPa·s (millipascal-seconds) and determines applications like thickening or film-forming. Higher viscosity grades create more gel-like solutions.

Q: How do HPMC grades vary in viscosity?

A: HPMC grades are categorized by viscosity ranges (e.g., low: 5-50 mPa·s, high: 50,000+ mPa·s at 2% concentration). Grades like K4M (medium) and E15 (high) indicate specific viscosity bands for targeted uses. Selection depends on the desired thickness in pharmaceuticals or construction materials.

Q: What is the typical viscosity of HPMC K4M?

A: HPMC K4M typically has a viscosity of ~4,000 mPa·s in a 2% aqueous solution at 20°C. This medium-viscosity grade is widely used in controlled-release tablets. It balances gel strength and solubility for drug delivery.

Q: Why use HPMC E15 for high-viscosity needs?

A: HPMC E15 offers high viscosity (~15,000 mPa·s in 1-2% solutions), ideal for thick coatings or adhesives. Its consistency ensures water retention in cement renders and plasters. E15 exceeds lower grades like K4M in thickening efficiency.

Q: How is HPMC viscosity measured accurately?

A: HPMC viscosity is tested via rotational viscometers using standardized solutions (e.g., 2% concentration per USP methods). Temperature control is critical as viscosity drops with heating. Results are benchmarked against grade specifications like K4M (3,500-5,600 mPa·s) or E15 (12,000-18,000 mPa·s).
