Basic Knowledge of Polyvinyl Chloride (PVC)

聚氯乙烯(Polyvinyl Chloride),简称PVC,是重要的有机合成材料。是一种无毒、无臭的白色粉末。化学稳定性很高，具有良好的可塑性。电绝缘性优良，一般不会燃烧。因其良好的物理性能和化学性能，被广泛应用于工业、建筑、农业、日用生活、包 装、电力、公用事业等领域。

Polyvinyl chloride, abbreviated as PVC, is an important organic synthetic material. It is a non-toxic and odorless white powder. High chemical stability and good plasticity. Excellent electrical insulation and generally does not burn. Due to its excellent physical and chemical properties, it is widely used in industries, construction, agriculture, daily life, packaging, electricity, public utilities, and other fields.

聚氯乙烯是合成树脂中重要的品种，从世界及中国范围内的消费量看，PVC消费量排在五大通用树脂中的第三位，低于聚乙烯、聚丙烯。从生产工艺路线看，除中国和极少几个国家以电石法工艺路线生产，绝大部分国家都是采用石油天然气路线，因此成本和市场价格不尽一致。

PVC is an important variety in synthetic resins. From the perspective of global and Chinese consumption, PVC consumption ranks third among the five general resins, lower than polyethylene and polypropylene. From the perspective of production process route, most countries use oil and gas route except China and a few countries that use carbide process route, so the cost and market price are not consistent.

国民经济的快速发展，带动中国PVC生产和消费的急剧膨胀。目前中国是世界上最大的PVC生产国和消费国。

The rapid development of the national economy has driven the rapid expansion of PVC production and consumption in China. Currently, China is the world's largest producer and consumer of PVC.

在我国，电石法和乙烯法两种生产工艺并存，影响产业链各环节的因素众多，加上煤炭、原油和电石等原材料价格的频繁波动，导致PVC价格短期内波动频繁且幅度剧烈，加剧了国内PVC生产企业、贸易商以及下游制品行业的经营风险，企业对套期保值存在较大的需求。

In China, there are two production processes, calcium carbide method and ethylene method, coexisting. There are many factors that affect various links in the industrial chain. In addition, the frequent fluctuations in raw material prices such as coal, crude oil, and calcium carbide have led to frequent and severe fluctuations in PVC prices in the short term, exacerbating the operational risks of domestic PVC production enterprises, traders, and downstream product industries. Enterprises have a great demand for hedging.
