With the continuous development of science and technology, Pva polyvinyl alcohol, as an important polymer compound, is widely used in various fields. Pva can achieve products with different functions by controlling key parameters such as polymerization degree, alcoholysis degree, and impurity content. In the market, Pva has many different models with certain differences and characteristics among them. Next, we will provide a detailed introduction to the differences and application scenarios of Pva models

Let's discuss one of the common Pva models - Pva1788. Pva1788 has high degree of polymerization and alcoholysis, and its solubility is good, which can be used to prepare high transparency hydrogel products. Due to its unique physical properties, Pva1788 is widely used in the medical and health field, such as creating waveforms to simulate human tissue. In addition, Pva1788 can also be used as a film-forming agent for electrolyte and nutrient slow-release systems, for soil improvement in the agricultural field

Another common model is Pva117. Compared to Pva1788, Pva117 has a lower degree of polymerization and slightly higher degree of alcoholysis. This makes Pva117 more easily soluble in water and has good adhesion and fluidity, making it widely used in the preparation of adhesives. Not only that, Pva117 can also be used as a stabilizer for preparing iron oxide nanoparticles, as well as an emulsifier in coatings

In addition, there is a special model of Pva, namely Pva217. The characteristics of Pva217 are low gelation temperature, good thermal stability, and wide application in the fiber field. In the textile industry, Pva217 can be used for needle spinning, giving the yarn higher tensile strength and lower fracture strength. In addition, Pva217 can also serve as a crosslinking agent for cellulose fibers and play an important role in textile processing

To sum up, as an important polymer compound, Pva has different models of products to choose from in different application fields. Pva1788 is suitable for the fields of healthcare and agriculture, while Pva117 is widely used in adhesives and coatings, while Pva217 is mainly used in the textile industry. By fully understanding the characteristics and application scenarios of various models of Pva, we can better choose Pva products that meet our needs and achieve better usage effects.
