Taiwan Changchun Petrochemical Co., Ltd. was founded in 1964 and invested in the research and development of Pva in 1971. Now its total production capacity ranks second in the world. The plant has been using the low alkali process of petroleum ethylene for production. The product quality is stable. The purity of the same model is about 1-3% higher than that of domestic products, and the alcoholysis degree is about 1-3% lower than that of domestic products. When used under the same conditions, the feeding amount is greatly reduced and the cost is reduced, which is generally recognized by the industry.
