东方roller---pvc发泡滚轮
描述：description：
　　东方roller---pvc发泡滚轮是采用连续发泡且发泡密度高的技术来制作，易清洗且不容易残留化学药剂。在干燥状态下能始终保持弹性和柔软度。在使用过程中，不需要加水保湿，而且耐摩擦性强，不易掉屑，抗张强度大，不易变形，耐药性佳。对于一般有机溶剂均有抗化性，长期置于酸，碱溶液中，也不容易产生变化。
dong fang roller---pvc foaming roller
a roller with excellent chemical resistance and water preservingcapabilities that is ideal for use after chemical processes. itstays soft and pliable without the need for pre-soaking, has goodabrasion resistance, and will not chip or shed.
