据石化新闻2020年7月20日休斯敦报道，美国4家聚氯乙烯（PVC）生产商日前先后宣布，除了7月份寻求和6月份同意的相同数目提价，他们寻求8月份PVC价格每磅再提高3美分。
熟悉包括台塑美国公司、西湖化学公司、美国新科公司和美国西方石油公司化学份公司运作的消息人士证实了7月16日至17日的最新提价公告。
上述4家PVC 生产商都没有回复记者的置评请求。
今年4月和5月，由于美国因疫情大流行而大面积停产PVC，购买陷于停顿，这种建筑原料的国内价格因此每磅下跌了8美分。到5月底，需求开始强劲反弹，生产商宣布6月份PVC价格每磅上调3美分，此次提价随后被接受。生产商随后宣布7月份PVC价格每磅再次上调3美分。
德克萨斯州、佛罗里达州和亚利桑那州等6月和7月的COVID-19确证病例数暴增抑制了需求反弹，导致一些市场消息人士表示，他们可能不会完全接受7月份的PVC提价。

US PVC producers seek third 2020 domestic price increase in August
All four US polyvinyl chloride producers have announced 3 cents/lb price increases for August, in addition to the same amount sought for July and accepted for June.
Sources familiar with company operations at Formosa Plastics USA, Westlake Chemical, Shintech, and OxyChem, the chemical division of Occidental Petroleum, confirmed the latest price increase announcements issued July 16-17.
The companies did not respond to requests for comment.
Domestic prices for the construction staple used to make pipes, window frames, vinyl siding, and other products fell 8 cents/lb in April and May as buying stalled amid widespread coronavirus pandemic-related shutdowns in the US. By late May, demand began rebounding strongly and producers announced 3 cents/lb price increases for June that were later accepted. Announcements of a second 3 cents/lb price increase for July followed.
COVID-19 spikes in some regions in June and July, such as Texas, Florida, and Arizona, has cooled the demand rebound, leading some market sources to say that the July increase may not be accepted in full.
