回顧PC原料市場(chǎng)，自9月始一直到現(xiàn)在，停工令！漲價(jià)函！裝置停產(chǎn)！事故頻發(fā)……聚碳酸酯價(jià)格聽到**多一句話還是"又漲價(jià)了！"。從一開始只是以為是階段性的躁動(dòng)，沒想到后來已漲成趨勢(shì)。這一連串的操作讓整個(gè)市場(chǎng)，就像一匹脫韁的野馬，拉都拉不住！而似乎就在***，PC市場(chǎng)迎來大轉(zhuǎn)變：原料貿(mào)易商拋貨，原料跌800-1000元/噸，市場(chǎng)無價(jià)格？影響因素上游動(dòng)態(tài)：昨日國(guó)內(nèi)雙酚A市場(chǎng)高位震蕩，供貨方報(bào)價(jià)窄幅震蕩，下游廠家抵觸高價(jià)，跟進(jìn)有限，場(chǎng)內(nèi)交投清淡。庫(kù)存供應(yīng)：PC行業(yè)廠家裝置逐漸恢復(fù)正常運(yùn)行，開工高位。下游需求：目前市場(chǎng)價(jià)格創(chuàng)近兩年**高水平，下***業(yè)成本壓力巨大，下游廠商剛需跟進(jìn)滯緩，場(chǎng)內(nèi)交投小單為主，或場(chǎng)外觀望等待為主。后市預(yù)測(cè)當(dāng)前國(guó)內(nèi)PC市場(chǎng)寬幅下跌，原料雙酚A上漲受限，場(chǎng)內(nèi)供貨方讓利出貨意向增強(qiáng)，商談重心下行。場(chǎng)內(nèi)交投節(jié)奏較快，現(xiàn)貨供不應(yīng)求。下游及終端廠家詢盤積極性較高，部分有囤貨意向！恰逢·感恩之日·，上海綠澳：感恩與您相遇，讓我們前進(jìn)的道路更有意義！感恩您的信賴，筆筆訂單皆是我們用心之作！未來的時(shí)間里，盼與您"攜手共進(jìn)。</p><p>
