Domestic large-scale calcium carbide PVC production enterprises vigorously promote the development strategy of circular economy, enlarge and strengthen the industrial chain with calcium carbide PVC as the core, and strive to build a large-scale industrial cluster integrating "coal-electricity-salt".At present, the sources of vinyl vinyl products in China are developing in a diversified direction, which has also opened up a new path for the procurement of raw materials for the PVC industry. Domestic coal-to-olefins, methanol-to-olefins, ethane-to-ethylene and other modern processes have made the supply of ethylene more abundant.
