E for excellent elephant
The viscosity of HPMC (Hydroxypropyl Methylcellulose) E5 typically ranges between 5,000 to 15,000 cP (centipoise) when measured at a 2% concentration in water at 20°C. This variation depends on factors like concentration and temperature. HPMC E5 is often used in pharmaceutical and food applications for its thickening and stabilizing properties. For specific applications, it’s best to refer to the manufacturer's data sheet for precise viscosity values.

In the context of HPMC K4M, the "K" typically refers to the viscosity grade of the hydroxypropyl methylcellulose (HPMC) polymer. HPMC K4M is a specific type of HPMC with a medium to high viscosity, commonly used in pharmaceutical formulations as a thickening agent, stabilizer, or controlled-release agent. The "4M" indicates a particular molecular weight and viscosity profile, which influences its properties and applications.
The Chords are: A flat 5, B 5, C sharp 5, E5, D sharp 5, E5, D sharp 5, E5, B5, C5 Hope this comes in useful
K means 1000 as a multiplier of 1000

In HPMC K4M, "K" refers to the viscosity grade of hydroxypropyl methylcellulose (HPMC). Specifically, HPMC K4M indicates a specific molecular weight and viscosity range that is suitable for various applications, particularly in pharmaceuticals and food products. The "4" and "M" denote the grade and the type of substitution of the cellulose ether, reflecting its properties and suitability for different formulations.
viscosity of hpmc k4m was 4000cps.
cps stands for centipoise.They have different viscosities.
HPMC K100M has a higher viscosity compared to HPMC K15M. The difference in viscosity is due to the molecular weight of the polymer, with higher molecular weight leading to higher viscosity. This will impact the flow and performance of the two polymers in various applications.
METHOCEL is a well known trademark of The Dow Chemical Company manufacturing cellulose ethers for various industries. Methocel is a trademark for methycellulose whereas HPMC E5 is Hydroxypropyl Methyl Cellulose with very low viscosity of 5 CPS (centipoise) used as rheology modifier as well as water retaining agent for film formation, synthetics adhesives as well as tablet coating. It has excellent water retaining properties. Samsung fine Chemicals, SE Tylose are one of the competitors of The Dow Chemical Company in the global market along with many Chinese companies.
