橡胶止水带是采用天然橡胶与各种合成橡胶为主要原料，掺加各种助剂及填充料，经塑炼，混炼，压制成型，其品种规格较多，有桥型、山型、P型、R型、U型、Z型、乙型、T型、H型、E型、Q型等。该止水材料具有良好的弹性，耐磨性、耐老化性和抗撕裂性能，适应变形能力强、防水性能好，温度使用范围-45℃-+60℃。当温度超过+70℃，以及强烈的氧化作用或受油类等有机溶剂侵蚀时，均不得使用该产品。

The rubber sealing strip is made of natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through mixing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, R type, U type, Z type, T type, H type, type, E type and Q type etc.. The sealing material has good elasticity, wear resistance, aging resistance and tear resistance. It has good deformation ability and good waterproof performance. Its temperature range is -45 degrees centigrade and -+60 degrees centigrade. This product should not be used when the temperature is higher than +70 degrees, and it is strongly oxidized or eroded by organic solvents such as oil.
