Polyvinyl alcohol, otherwise known as PVA, seems appropriate for use in various industries because of the unique characteristics it has. “This paper then aims to analyze specific performance parameters in PVA applications, concentrating on the differences between Polyvinyl Alcohol Series 88 and Series 99 in terms of the industries such as textiles, pharmaceuticals and packaging.”
PVA is well recognized for its ability to form films, emulsions and adhesives with ease. There is a tendency for the 88 series to hold lower degrees of hydrolysis and molecular weight compared to the 99 series. These variations are important since they affect their chemical and physical properties. This makes them best suited for different uses. For example, when it comes to applying the 88 series, water solubility and flexibility are the two most critical factors to critically take into account while the 99 series is used for areas requiring much stronger and highly resistant to solvents due to the higher molecular weight.
PVA performance parameters can be broadly classified in multiple domains such as solubility, viscosity, tensile strength, thermal stability among others. The 88 Series, with a lower degree of hydrolysis, has higher solubility in cold water. This is ideal for applications where there is a need for quick dissolution of the polymer. The 99 Series however has greater thermal stability and greater tensile strength which are critical in applications where the polymer has to withstand greater heat and durability.
The 88 Series is generally used in the textile industry as a sizing agent for fibrous materials, and provides a coating onto the fibers to facilitate the weaving process. This not only increases the effectiveness of the weaving process, but also improves the surface finish of the fabric. The 99 Series on the other hand is used for production of high-end performance textiles which demand its strength and stability for their applications. Its strength against extreme chemical treatments also make it an optimal choice for construction of technical textiles in industry usage.
In the pharmaceutical industry, the 88 series and 99 series are usually offered depending on how the drug is to be formulated. This is largely because of its solubility characteristics that the 88 series is often used for when developing controlled-release drug delivery systems. On the other hand, the 99 Series has been used in applications that require durable film-forming in producing biodegradable materials. With the focus of the global economy on sustainability, there is a lot of innovation on the use of PVA products because of the need to find biodegradable solutions.
Niche PVA products are in higher demand as more sectors of the economy advance. The ever increasing research on how to make PVA better by making it more biodegradable or weather resistant certainly dictates how this polymer would be in the future. Moreover, PVA usage in the textile industry and packaging, in particular, is growing due to the global trend of using eco-friendly materials. Such companies that are strong on innovativeness as well as sustainability in their PVA offerings are most likely to have a competitive advantage in the market.
