They can also provide customized solutions, adjusting viscosity, particle size, or other properties to meet unique requirements.?

2. Timely Delivery and Logistics: With established supply chains and efficient logistics networks, suppliers ensure on - time delivery, minimizing production delays for customers. They also offer flexible packaging options to suit different transportation and storage needs.?

3. After - Sales Service and Problem - Solving: Post - sales support includes troubleshooting formulation issues, providing application guidance, and offering continuous technical updates. Suppliers often collaborate with customers to optimize processes and improve product performance.?

4. Regulatory Compliance Support: In industries like pharmaceuticals and food, HPMC suppliers assist customers in meeting regulatory standards by providing relevant certifications (e.g., FDA, EU standards) and documentation, ensuring compliance with safety and quality regulations.

HPMC Hydroxypropyl methyl cellulose CAS 9004-65-3 is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products. As a food additive, hypromellose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin.

Properties

1) Appearance: HPMC is a nonionic cellulose ether, white grayish-white powder or granule,odorless and flavorless, soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending on the degree of substitutions, practically insoluble in hot water, ethylene glycol and toluene. HPMC is dissolved in a mixture of 10% methanol and 90% methylene chloride to form colloidal solutions.
2) The solution of HPMC has surface activity, high transparency, and stable performance. When heated at certain temperature, the solution becomes cloudy or forms flocculent gel. However, the solution becomes clear again after cooling. Different types of HPMC have different gelation temperatures. The solubility varies with the viscosity. The lower the viscosity, the higher solubility it has. The different types of HPMC are different in some properties and their solubility in water is not affected by pH.
3) Particle sizes: 100% pass rate in 80 mesh.
4) Apparent density: 0.25-0.70 g/mL (usually about 0.5 g/mL),specific density 1.26-1.31mL.
5) Color change temperature:190-200°C; Carbonization temperature:280-300°C.
6) Surface tension:42-56 dyn/cm (2% aqueous solution).
7) The higher methoxy content in HPMC, the lower gelation temperature, and the higher solubility in water and surface activity.

8) HPMC has some other characteristics, for example, thickening property, pH stability, retention of water, excellent film-forming property, good disperse and adhesion ability
