據石化新聞2020年7月20日休斯敦報道，美國4家聚氯乙烯（PVC）生產商日前先后宣布，除了7月份尋求和6月份同意的相同數目提價，他們尋求8月份PVC價格每磅再提高3美分。

熟悉包括臺塑美國公司、西湖化學公司、美國新科公司和美國西方石油公司化學份公司運作的消息人士證實了7月16日至17日的最新提價公告。

上述4家PVC 生產商都沒有回復記者的置評請求。

今年4月和5月，由于美國因疫情大流行而大面積停產PVC，購買陷于停頓，這種建筑原料的國內價格因此每磅下跌了8美分。到5月底，需求開始強勁反彈，生產商宣布6月份PVC價格每磅上調3美分，此次提價隨后被接受。生產商隨后宣布7月份PVC價格每磅再次上調3美分。

德克薩斯州、佛羅里達州和亞利桑那州等6月和7月的COVID-19確證病例數暴增抑制了需求反彈，導致一些市場消息人士表示，他們可能不會完全接受7月份的PVC提價。

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.
