style="text-indent:25px">分類情況PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場的2/3，軟PVC占1/3。軟PVC一般用于地板、天花板以及皮革的表層，但由于軟PVC中含有增塑劑(這也是軟PVC與硬PVC的區(qū)別)，物理性能較差(如上水管需要承受一定水壓，軟質(zhì)PVC就不適合使用)，所以其使用范圍受到了局限。硬PVC不含增塑劑，因此易成型，物理性能佳，因此具有很大的開發(fā)應(yīng)用價值。聚氯乙烯材料生產(chǎn)過程中，勢必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑，那PVC管材亦是***無味環(huán)保的制品。</p><p> 發(fā)展歷史PVC型材產(chǎn)品經(jīng)歷了導(dǎo)入期和高速發(fā)展期，從時間上看，可以分別定義為二十世紀(jì)80年代-90年代中期和1995年-2002年左右。2003年以后，PVC型材行業(yè)進(jìn)入了轉(zhuǎn)型期。在產(chǎn)品的導(dǎo)入期:生產(chǎn)商普遍追求低造價，簡化了門窗型材斷面，配方中大量填充碳酸鈣，導(dǎo)致產(chǎn)品性能很低，很多質(zhì)量問題的出現(xiàn)影響了產(chǎn)品的推廣。 </p> <p> 1995年開始，一批有實(shí)力的企業(yè)，開始消化吸收國外歐式型材的技術(shù)精華，研制出自己的門窗系列，成為國內(nèi)塑料門窗的主導(dǎo)，推動門窗的技術(shù)更新和發(fā)展，也使整個行業(yè)得到了空前的發(fā)展和高速增長。進(jìn)入產(chǎn)品成熟期后，也即從2003年起，許多弊端開始反應(yīng)出來，過高的利潤率導(dǎo)致盲目投資過多，使行業(yè)綜合產(chǎn)能近300萬噸，遠(yuǎn)高于市場需求;很多新進(jìn)入的投資者沒有從產(chǎn)品創(chuàng)新、技術(shù)創(chuàng)新入手，而是簡單模仿，甚至偷工減料，假冒偽劣，行業(yè)市場競爭處于非健康狀態(tài)。原料市場價格不斷上揚(yáng)，加劇這種非健康的競爭，使部分企業(yè)經(jīng)營處于困境，出現(xiàn)停產(chǎn)或半停產(chǎn)狀態(tài)。
