This article discusses the two primary PVC production methods: the calcium carbide acetylene process and the ethylene oxychlorination process. The acetylene process is straightforward but faces environmental restrictions due to high energy consumption and toxic catalysts. In contrast, the ethylene method, while more complex and costly, effectively utilizes chlorine and manages waste. Recommended products include Zhongtai and XINFA PVC resin SG-5.
