What is K in HPMC k4m?
K means gelling temperature is between 70-90℃. The viscosity is 4000cps.
What is the difference between HPMC and HPC?
Nisso HPC (hydroxypropyl cellulose) is available in high-molecular weight, fine powder grades designed for direct compression sustained release tablets. Compared to HPMC, tablets made with HPC are: easier to manufacture with lower compression force. more robust and less variable in-vitro and in-vivo.
What is HPMC K15M?
METHOCEL™ K15M is an HPMC polymer with moderate hydroxypropyl substitution. It is typically used as a thickener, binder, or suspension aid in coatings, adhesives, or cleaners where a thixotropic rheology is desired. METHOCEL™ K15M is also used to control the viscosity of latex architectural paints and coatings.
What is HPMC E5?
Hydroxypropyl methylcellulose(HPMC) E5 is a semisynthetic, viscoelastic polymer, it is a cellulose ether. HPMC can be also used as a suspending agent in the suspension, a matrix material for an ophthalmic agent, a skeleton material for hydrophilic gel skeleton sustained-release, and gastric floating tablets.
What is Methocel K4M?
METHOCEL™ K4M is a medium molecular weight hydroxypropyl methylcellulose (HPMC) thickener. It will yield a viscosity of 4,000 cP at 2% in water and is typically used in coatings, adhesives, and ceramics.
What is Methocel K100?
Methocel™ K100 by Dow is cellulose ether. Acts as dispersing agents for polyvinylchloride (PVC). Used for applications where high purity is important. Provides particle size control, uniform particle size distribution, and porosity that can be optimized for many PVC end-uses. Methocel™ K100 is used for rigid PVC.
What is hydroxypropyl methylcellulose uses?
It is extensively used in the food industry as a stabilizer, as an emulsifier, as a protective colloid, and as a thickener. HPMC is used as a raw material for coatings with moderate strength, moderate moisture and oxygen barrier properties, elasticity, transparency, and resistance to oil and fat.
Is hydroxypropyl methylcellulose a drug?
Hydroxypropyl methylcellulose belongs to the group of medicines known as artificial tears. It is used to relieve dryness and irritation caused by reduced tear flow.
What is Methocel used for?
METHOCEL™ 228 is a modified HPMC that is used as a thickener in tape joint compounds, crack fillers, and other flexible construction materials. METHOCEL™ 240 is a high molecular weight hydroxypropyl methylcellulose polymer that is used as a thickener in water based coatings, inks & adhesives.
What is Methocel E4M?
METHOCEL™ E4M Premium is a water soluble HPMC polymer with moderate hydroxypropyl substitution and high methoxy content. METHOCEL™ E4M Premium carries approvals for use in pharmaceutical applications and has been used in many cleaning applications due to its pH stability and solvent compatibility.
What is Methocel K100M?
Methocel® K100M is “K” Grade Hydroxypropyl Methylcellulose. It forms a soft fluid gel at 158-194°F (70-90°C). It has a very high viscosity of 100,000 cP.
Is hydroxypropyl methylcellulose the same as methylcellulose?
Hydroxypropyl Methyl Cellulose has better enzyme resistance than Methyl Cellulose, and the possibility of enzymatic degradation of Hydroxypropyl Methyl Cellulose is less than that of MC. 6. Hydroxypropyl Methyl Cellulose has higher adhesion on mortar construction than Methyl Cellulose.
