HAOTAIXING ROLLER---PVC FOAMING ROLLER
A roller with excellent chemical resistance and water preserving
capabilities that is ideal for use after chemical processes. It
stays soft and pliable without the need for pre-soaking, has good
abrasion resistance, and will not chip or shed.
特性：FEATURE：
1． 发泡密度高且采用连续发泡式发泡，具有优良的耐酸碱性，耐久性。
1.Continuous foaming process with high foaming intensity; It has
excellent chemical resistance and abrasion resistance.
2. 在干燥状态下能保持弹性及柔软度，且不干硬，无需加水保湿。
2. Keeping flexibility and softness in dry state without
becoming dry and hard; no wetting process is needed.
3.耐摩擦性强，不易掉屑，抗张强度大，不易变形。
3.Excellent antifriction capability against chips; good tensile
strength against deformation.
4.耐花性佳，对于一般有机溶剂均有抗化性，长期置于于酸、碱溶液中，也不容易产生变化。
4.Agent resistance capability is good enough to resist general
organic solvents; it will not change in nature after being put into
acid or basic solution for a long time.
