我国PP-R无规共聚聚丙烯管材市场近年来呈现饱和状态,与此相应的投资应该审慎行事。近年来,国内塑料机械设备已经形成供大于求的局面,塑料机械制造厂家竞争异常激烈;PP-R管材生产线价格也由每条生产线200万元左右下降到目前的50多万元,下降幅度大,速度也快。据中国塑料加工协会 China PP-R random copolymerization polypropylene pipe market saturation in recent years, with which the corresponding investment should be cautious. In recent years, the domestic plastic machinery and equipment have formed a situation of oversupply, plastic machinery manufacturers extremely competitive; PP-R pipe production line price from about 200,000 yuan per production line down to the current more than 500,000 yuan, a significant decline , Fast speed.
