Polyvinyl chloride (PVC) is one of the five major synthetic resins. Its physical appearance is white powder, non-toxic and tasteless. Mainly used for processing building doors and windows, drainage pipes, wires and cables, film packaging and other fields. With the rapid development of national economy, the production and consumption of PVC in China have increased rapidly, and it has become the largest producer and consumer of PVC in the world. In recent years, affected by the sharp fluctuation of coal and crude oil prices, the price of PVC market has changed dramatically and frequently, and the operating risks of domestic spot enterprises have increased. The listing of PVC futures is an urgent task to avoid operational risks and achieve steady development. Therefore, Dalian Commodity Exchange (hereinafter referred to as Dashang Exchange) completed the design of PVC futures contract after in-depth investigation and argumentation and extensive solicitation of opinions from all parties.
