In 2007, the national PVC production was 9.72 million tons, of which 719.2 million tons were produced by the calcium carbide method, accounting for 74.0% of the total output. PVC production using the ethylene method raw material route was 1.350 million tons, accounting for a total of 13.4% of the total output. The production of PVC using the raw materials of imported ethylene chloride and ethylene dichloride was 1.22 million tons, accounting for 12.6% of the total output. By the end of 2008, the domestic PVC production capacity of 16.5 million t / a, calcium carbide PVC production capacity super
