What are the benefits of using hydroxypropyl methylcellulose?
Hydroxypropyl methylcellulose is also known as HPMC and it has many applications in our life. At the same time, there are many, many uses for it. Let’s look at the advantages of using hydroxypropyl methylcellulose today.
HPMC is the raw material substrate to produce oil and fat, which can realize the utilization of all sugars, improve the utilization rate of raw materials, reduce the amount of substrate residues in the fermentation broth, and reduce the cost of wastewater treatment. The characteristics of this hydroxypropyl methylcellulose are beneficial for batch, fed-batch and continuous fermentation processes are optimized to avoid a series of problems, such as controlling the composition and dilution rate of the medium; it also facilitates the regulation of the fermentation process .
Since the properties of hydroxypropyl methylcellulose (HPMC) are similar to other water-soluble ethers, it can be used as a film-forming agent, thickener, emulsifier, stabilizer, etc. in latex paint and water-soluble resin paint components. The film has good abrasion resistance, uniform coating and adhesion, and has improved surface tension, stability to acids and bases, and compatibility with metallic pigments.
HPMC has good effect as a thickener for white water-based polyvinyl acetate coatings. The degree of substitution of the cellulose ether is increased, and the resistance to bacterial attack is also enhanced.
