The main characteristics of pharmaceutical grade PVA include film properties, gas barrier properties, adhesion, and hygroscopicity. Goshenol has good gas resistance to many gases, such as oxygen, nitrogen, carbon dioxide, and the tablets and pills made of it can maintain the efficacy for a long time. At the same time, as a polyvinyl alcohol for removing impurities, it also has the following characteristics:

Since there is little odor, the fragrance of the spice can be maintained. Most domestic masks contain acetic acid, so a lot of spices need to be added to the mask. Spices are also a little harmful to the human body. Therefore, adding EG series can remove the acetic acid smell and reduce the use of spices. Due to the low content of sodium, the increase in crystallite size during sintering of the ceramic is small. And when the ceramic is sintered, the thermal decomposition of polyvinyl alcohol is slow, making it difficult for the ceramic to crack. Therefore, it has excellent properties when used as a ceramic tackifier. Improve electrical properties such as insulation, good film strength, good gas barrier properties, and gloss.

Since there are few impurities, it is excellent in heat resistance in drying, heat treatment, molding process, and the like.
