Frequently Asked Questions
Q: What is HPMC and how is it prepared?
HPMC (Hydroxypropyl Methylcellulose) is a semi-synthetic nonionic cellulose mixed ether. It is prepared through chemical modification of natural cellulose, typically using cotton or wood as raw materials, which undergo alkalization followed by etherification with propylene oxide and chloromethane.
Q: What are the key performance characteristics of HPMC?
Key characteristics include excellent thickening properties, good film formation (tough, water-resistant, flexible), excellent biocompatibility (non-toxic and non-irritating), high water solubility, and environmental degradability.
Q: In which industries is HPMC primarily used?
HPMC is widely used in the construction industry (cement mortar, adhesives), coating industry (thickeners, stabilizers), pharmaceutical field (film coatings, capsule shells, sustained release), and the food industry (stabilizers, emulsifiers). It also serves industries like daily chemicals, ceramics, textiles, and synthetic resins.
Q: How should HPMC be stored and handled?
It should be stored in a dry, clean, and cool place to maintain its quality and performance. During usage, it is important to select the appropriate dissolution method based on the specific model being used.
Q: How do the gel temperatures vary among HPMC models?
According to technical indicators, gel temperatures vary by model: Model E (58.0-64.0℃), Model F (62.0-68.0℃), Model J (68.0-75.0℃), and Model K (70.0-90.0℃).
