Good Price C14H16N4 Hydroxypropyl Methylcellulose Phthalate
Basic information:
Hydroxypropylmethylcellulose phthalate (HPMC-P) is a synthetic polymer commonly used in pharmaceuticals, building materials, personal care products, and more. The following are its general physical and chemical properties:
Physical properties:
Appearance: Usually white or white-like powdery substance.
Solubility: It has good solubility in water and forms a colloidal solution.
Thermal stability: Under appropriate conditions, it has certain thermal stability and can be used in processes such as thermoforming.
Chemical properties:
Chemical structure: HPMC-P is polymerized from methacrylate monomers and phthalate monomers, and has functional groups such as hydroxyl and acryloyl groups.
pH stability: Stable under neutral or weakly alkaline conditions. For different grades of HPMC-P, the pH stability range may be different.
Compatibility with other substances: usually has good compatibility with many organic solvents and other polymers.
It should be noted that the properties of specific HPMC-P may vary depending on the manufacturer, product grade and use, so it needs to be evaluated based on actual conditions in specific applications.
